Origin theories of Christopher Columbus

Posthumous representation of Christopher Columbus, as depicted in The Virgin of the Navigators by Alejo Fernández, 1531–36

The ethnic or national origin of explorer Christopher Columbus (1450 or 1451 – 1506) has been a source of speculation since the 19th century.^[1] The consensus among historians is that Columbus's family was from the coastal region of Liguria, that he was born and spent his boyhood and early youth in the Republic of Genoa, in Genoa, in Vico Diritto, and that he subsequently lived in Savona, where his father Domenico moved in 1470. Much evidence derives from documents concerning Columbus's immediate family connections in Genoa and opinions voiced by contemporaries on his Genoese origins, which few dispute.

Other hypotheses exist, none of which are broadly accepted. Reviewing them, British historian Felipe Fernández-Armesto writes:^[2]

The Catalan, French, Galician, Greek, Ibizan, Jewish, Majorcan, Scottish, and other Columbuses concocted by historical fantasists are agenda-driven creations, usually inspired by a desire to arrogate a supposed or confected hero to the cause of a particular nation or historic community – or, more often than not, to some immigrant group striving to establish a special place of esteem in the United States. The evidence of Columbus's origins in Genoa is overwhelming: almost no other figure of his class or designation has left so clear a paper trail in the archives.

Genoese origin

Documents

In a 1498 deed of primogeniture, Columbus writes:

Siendo yo nacido en Genova... de ella salí y en ella naci...^{[3][nb 1]}

— As I was born in Genoa... came from it and was born there...

Many historians affirm the document's authenticity; others believe it apocryphal.^{[nb 2]} Some believe that the fact that it was produced in court, during a lawsuit among the heirs of Columbus, in 1578, does not strengthen the case for its authenticity.^[6]

A letter from Columbus, dated 2 April 1502, to the Bank of Saint George, the oldest and most reputable of Genoa's financial institutions, begins with the words:

Bien que el coerpo ande aca el coracon esta ali de continuo...^[7]

— Though my body is here, my heart is constantly there...

Though some people consider this letter unreliable, the majority of scholars believe it genuine. Examination by graphologists testifies in favour of authenticity.^[6] The letter is one of a group of documents entrusted by Columbus to a Genoese friend, after the negative experiences of his third voyage, before setting out on his fourth.

In the spring of 1502, Columbus collected notarized copies of all the writings concerned with his rights to the discovery of new lands. He sent these documents to Nicolò Oderico, ambassador of the Republic of Genoa. To Oderico he also gave "the letter to the Bank of Saint George", in which he announced that he was leaving the bank one-tenth of his income, with a recommendation for his son Diego. Oderico returned to Genoa and delivered the letter to the bank. The bank replied on 8 December 1502, lauding the gesture of their "renowned fellow-citizen" towards his "native land". The reply, unfortunately, never reached its destination; Columbus, back in Castile after his fourth voyage, complained about this in another letter to Ambassador Oderico, dated 27 December 1504, and promptly annulled the bequest.

The first letter was preserved in the archives of the Bank of Saint George until it was taken over by the municipality of Genoa; the other three remained in the Oderico family archives until 1670, when they were donated to the Republic of Genoa. After the fall of the Republic, they passed to the library of one of its last senators, Michele Cambiaso, and were finally acquired by the city of Genoa. There are also public and notarial acts (more than a hundred) — copies of which are conserved in the archives of Genoa and Savona — regarding Columbus's father, Columbus himself, his grandfather, and his relatives.^{[nb 3]}

The life of Admiral Christopher Columbus by his son Ferdinand

A biography written by Columbus's son Ferdinand (in Spanish and translated into Italian), Historie del S. D. Fernando Colombo; nelle quali s'ha particolare, et vera relatione della vita, et de' fatti dell'Ammiraglio D. Christoforo Colombo, suo padre; Et dello scoprimento, ch'egli fece delle Indie Occidentali, dette Nuovo Mondo ("Accounts of His Lordship Ferdinand Columbus; among which there are particulars and a true relation of the life, and of the deeds of the Admiral, Sir Christopher Columbus, his father; and of the discovery, which he made, of the West Indies, called the New World," abbreviated as "The life of the Admiral Christopher Columbus by his son Ferdinand"), exists.^{[8][9][nb 4]} In it, Ferdinand claimed that his father was of Italian aristocracy. He describes Columbus to be a descendant of a Count Columbo of the Castle Cuccaro (Montferrat). Columbo was in turn said to be descended from a legendary Roman General Colonius. It is now widely believed that Christopher Columbus used this persona to ingratiate himself with the aristocracy, an elaborate illusion to mask a humble merchant background.^[11] Ferdinand dismissed the fanciful story that the Admiral descended from the Colonus mentioned by Tacitus. However, he refers to "those two illustrious Coloni, his relatives."^{[nb 5]} According to Note 1, on page 287, these two "were corsairs not related to each other or to Christopher Columbus, one being Guillame de Casenove, nicknamed Colombo, Admiral of France in the reign of Louis XI". At the top of page 4, Ferdinand listed Nervi, Cogoleto, Bogliasco, Savona, Genoa and Piacenza (all inside the former Republic of Genoa)^{[nb 6]} as possible places of origin. He also stated:

Colombo ... was really the name of his ancestors. But he changed it in order to make it conform to the language of the country in which he came to reside and raise a new estate ...

In chapter ii, Ferdinand accuses Agostino Giustiniani of telling lies about the discoverer:

Thus this Giustiniani proves himself to be an inaccurate historian and exposes himself as an inconsiderate or prejudiced and malicious compatriot, because in writing about an exceptional person who brought so much honor to the country ...

In chapter v, he writes:

And because it was not far from Lisbon, where he knew there were many Genoese his countrymen, he went away thither as fast as he could ...

Ferdinand also says (chapter xi) that before he was declared admiral, his father used to sign himself "Columbus de Terra rubra," that is to say, Columbus of Terrarossa, a village or hamlet near Genoa. In another passage, Ferdinand says that his father went to Lisbon and taught his brother Bartholomew to construct sea charts, globes and nautical instruments; and sent this brother to England to make proposals to Henry VII of his desired voyage. Finally, Ferdinand says incidentally (chapter lxxii) that Christopher's brother, Bartholomew Columbus named the new settlement Santo Domingo in memory of their father, Domenico.

The publication of Historie has been used by historians as providing indirect evidence about the Genoese origin of Columbus.

The testimony of the ambassadors

In April 1501, in the feverish atmosphere of the discovery, Nicolò Oderico, ambassador of the Genoese Republic, after praising the Catholic Sovereigns, went on to say that they "discovered with great expenditure hidden and inaccessible places under the command of Columbus, our fellow-citizen, and having tamed wild barbarians and unknown peoples, they educated them in religion, manners and laws". Furthermore, two diplomats from Venice added the appellation "Genoese" to Columbus's name: the first, Angelo Trevisan, in 1501,^{[nb 7]} the second, Gasparo Contarini, in 1525.^{[nb 8]} In 1498, Pedro de Ayala, Spanish ambassador to the English court, mentioned John Cabot, "the discoverer, another Genoese, like Columbus".^[12] All these references were published, along with reproductions of some of the original documents, in the City of Genoa volume of 1931.

Support for the Genoese origin from contemporary European writers

The historian Bartolomé de las Casas, whose father traveled with Columbus on his second journey and who personally knew Columbus's sons,^{[nb 9]} writes in chapter 2 of his Historia de las Indias:^[14]

This distinguished man was from the Genoese nation, from some place in the province of Genoa; who he was, where he was born or what name he had in that place we do not know in truth, except that before he reached the Nation in which he arrived, he used to call himself Cristóbal Colombo de Terrarubia.

The historian Gonzalo Fernández de Oviedo y Valdés, writes that Domenico Colombo was the Admiral's father;^[15] and in chapter 2, book 3 of his Historia general y natural de las Indias:^[16]

Christopher Columbus, according to what I have learned from men of his nation, was originally from the province of Liguria, which is in Italy, where the city and the Seignory of Genoa stands: some say that he was from Savona, others that he was from a small place or village called Nervi, which is on the eastern seashore two leagues from the self same city of Genoa; but it is held to be more certain that he may have been originally from Cugurreo (Cogoleto) near the city of Genoa.

Many contemporary writers agree that the discoverer was Genoese:^[4][6]

• The Portuguese Rui de Pina wrote two works, Chronica d'El Rey, dom Affonso and Chronica d'El Rey, dom João II. It has been ascertained that the manuscripts had been completed before 1504, although they were published in the Eighteenth century. Chapter 66 in the second manuscript, "Descubrimiento das Ilhas de Castella per Collombo," explicitly states, "Christovan Colombo italiano."
• In the 1513 edition of the Map of the New World from Ptolemy,^[17] it says: "This land with the adjacent islands was discovered by the Genoese Columbus, sent by the King of Castile."
• The Turkish geographer Piri Ibn Haji Mehmed, known as Piri Reis, in his map of 1513, writes: "These coasts are called the coasts of the Antilles. They were discovered in the year 896 of the Arabic calendar. It is said that a Genoese infidel, Columbus by name, discovered the place."^{[nb 10]}
• Hernando Alonso de Herrera, in his anti-Aristotelian dissertation, completed in Salamanca in 1516, and published in Latin and Spanish, wrote: "Xristoval Colon ginoves."
• In a Portuguese map of 1520,^{[nb 11]} it is said: "Land of the Antipodes of the King of Castile, discovered by Christopher Columbus Genoese."
• The German Peter von Bennewitz writes, in 1520, in the Typus Orbis Universalis:^[19] "In the year 1497 (sic) this land (America) with the adjacent islands was discovered by Columbus, a Genoese by mandate of the King of Castile."
• The German Johannes Schöner states in the Globus of 1520:^[20] "This (island) produces gold, mastic, aloes, porcelain, etc. and ginger — Latitude of the island 440 miles — Longitude 880 — discovered by Christopher Columbus Genoese, captain of the King of Castile in the year of Our Lord 1492."
• The Spaniard Francisco López de Gómara writes:^[21] "Christopher Columbus was originally from Cogurreo or Nervi, a village of Genoa, a very famous Italian city."
• The Portuguese Garcia de Resende, poet and editor, writes:^[22] "Christouao Colombo, italiano."
• The Swiss Heinrich Glarean (Loriti) writes:^[23] "To the west there is a land they call America. Two islands, Hispaniola and Isabella: which regions were travelled, along the coast, by the Spaniards, by the Genoese Columbus and by Amerigo Vespuzio."
• The Spaniard Hieronymo Girava, who lived in the first half of the 16th century, writes:^[24] "Christoval Colon Genoese, great seaman and mediocre cosmographer."
• The Portuguese João de Barros writes: "As all men declare, Christovão Colom was of Genoese nation, a man expert, eloquent and good Latinist, and very boastful in his affairs";^{[nb 12]} and: "As in this kingdom came Christopher Columbus Genoese, who had just discovered the western islands that now we call Antilles."^[26]
• The German known as Giovanni Boemo Aubano, of the first half of the 16th century, writes:^[27] "Christoforo Palombo, Genoese, the year 1492."
• The Flemish Abraham Ortelius, writes:^[28] "It seems to surpass the bounds of human wonder that all this hemisphere (that today is called America and, because of its immense extent, the New World) remained unknown to the ancients until the Christian year 1492, in which it was first discovered by Christopher Columbus, Genoese."
• The Portuguese Damião de Góis, writes:^[29] "The Genoese Columbus, a man expert in nautical arts" ; and, in the index: "Columbi genuen- sis, alias Coloni commendatio."^{[nb 13]}
• The Spaniard Nicolás Monardes, writes:^[31] "In the year 1492 our Spaniards were led by don Christoval Colon, native of Genoa, to discover the West Indies."
• The German Laurentius Surius, writes:^[32] "There was at the court of the King of Spain a certain Christopher Columbus whose homeland was Genoa."
• In 1579, for the Cristoph Pantin's edition, the yearbooks of the Genoese Senate were published, in Antwerp, edited by Petro Bizaro: Senatus Populique Genuensis rerum domi forisque gestarum historiae atque annales. Among what is written to celebrate many industrious Genoese men, you can read that: "cum Christophoro Columbo navalis scientiae absolutissima peritia apud omnem venturam posteritatem, juro optima aliqua ex parte conferri vel comparari possit."
• The Portuguese Fernão Vaz Dourado in the Atlante of 1580,^[33] notes: "Land of the Antipodes of the King of Castile discovered by Christopher Columbus Genoese."
• The Spaniard Alvaro Gomez, writes:^[34] "Thanks to the eager industry of Christopher Columbus Genoese, word was brought to our Sovereigns of an unknown world."
• The Frenchman Gilbert Génebrard, writes:^[35] "Ferdinand, at the urging of his wife Isabella, Queen of Castile, Leòn and Aragon, sent Christopher Columbus Genoese to seek new land."
• The Swiss Theodor Zwinger, who died in 1588, was the author of the Theatrum Humanae Vitae, Basle 1604. In the index we read: "Cristoforo Colono, or Colombo Genoese."
• On an unspecified date, certainly prior to 1591, the Turk Basmagi Ibrahim published a book, written by a Turkish author who has remained anonymous, entitled Turich-i-Hind-i garbi iachod hadis-i-nev (History of the West Indies, in other words the New Story). The third chapter of this book dedicated to the discoverer of the "New World or New Land," states: "From the village of Nervi, which is among the Genoese possessions, a man who was born who had the name Christopher and the surname Columbus. Since he had completed journeys by land and by sea [...] he stayed on an island by the name of Madeira [...] under the domain of the wretched (sic) Portugal."
• The Flemish Theodor De Bry, writes:^[36] "From everything it can be stated with certainty that it was first discovered by Christopher Columbus Genoese."
• The Portuguese Gaspar Frutuoso, in a sixteenth-century manuscript entitled As Saudades da terra, printed by Alvaro Rodriguez Azevedo in 1873 in Funchal (Madeira), writes in the Anales of Porto Santo: "On this island the great Christovao Colombo, the Genoese, resided for some time."
• The German David Chytraeus writes:^[37] "Primum Novum Orbem in occidente, omnibus antea ignotum et inaccessam... pervestigare et aperire... Christophorus Columbus Genesis, admirand ad omnen posteritatem ausu et industria coeperat."
• In the volume published by the City of Genoa the testimony is cited of the historian Andres Bernaldez, who died in 1513. He was the author of a Historia de los Reyes Catolicos don Fernando y dona Isabel. In this work, belatedly published in Seville in 1869, it is written:^[38] "In the name of Almighty God, a man of the land of Genoa, a merchant of printed books who was called Christopher Columbus." Actually, in the original text of Bernaldez, it says "land of Milan". However, this is merely lack of precision. In the 15th century, the Republic of Genoa was alternately fully and legally dependent on the Duchy of Milan and the latter's satellite. The editor rightly interpreted the Milanese reference in the sense of Genoese origin.

Columbus's Genoese birth is confirmed by the works of the English Hakluyt (1601), of the Spaniard Antonio de Herrera (1612), the great Spanish dramatist Lope de Vega (1614), a paper manuscript dated 1626, conserved in Madrid's National Library, the works of the German Filioop Cluwer (1677), the German Giovanni Enrico Alsted (1649), the French Dionisio Petau (1724), and the Spaniard Luigi de Marmol (1667). This list represents the early writings of non-Italians. In addition, there were sixty-two Italian testimonies between 1502 and 1600. Of these, fourteen are from Ligurian writers.^{[nb 14]}

Conformable to the testament in Seville (3 July 1539) is the evidence of Ferdinand Columbus, who states that his father was conterraneo (of the same country) with Mons. Agostino Giustiniani, who was, beyond all doubt,^[39][40] born at Genoa:

Hijo de don Cristóbal Colón, genovés, primero almirante que descubrió las Indias ...^[41]

— Son of Christopher Columbus, Genoese, admiral who first discovered the Indies ...

Historians

Alleged house of Christopher Columbus in Genoa, Italy.

Most scholars agree that Columbus was Genoese.^{[nb 22]}

Samuel Eliot Morison, in his book Christopher Columbus: Admiral of the Ocean Sea, notes that many existing legal documents demonstrate the Genoese origin of Columbus, his father Domenico, and his brothers Bartolomeo and Giacomo (Diego). These documents, written in Latin by notaries, were legally valid in Genoese courts. The documents, uncovered in the 19th century when Italian historians examined the Genoese archives, form part of the Raccolta Colombiana. On page 14, Morison writes:

Besides these documents from which we may glean facts about Christopher's early life, there are others which identify the Discoverer as the son of Domenico the wool weaver, beyond the possibility of doubt. For instance, Domenico had a brother Antonio, like him a respectable member of the lower middle class in Genoa. Antonio had three sons: Matteo, Amigeto and Giovanni, who was generally known as Giannetto (the Genoese equivalent of "Johnny"). Giannetto, like Christopher, gave up a humdrum occupation to follow the sea. In 1496 the three brothers met in a notary's office at Genoa and agreed that Johnny should go to Spain and seek out his first cousin "Don Cristoforo de Colombo, Admiral of the King of Spain," each contributing one third of the traveling expenses. This quest for a job was highly successful. The Admiral gave Johnny command of a caravel on the Third Voyage to America, and entrusted him with confidential matters as well.

On the topic of Columbus's being born somewhere besides Genoa, Morison states:

Every contemporary Spaniard or Portuguese who wrote about Columbus and his discoveries calls him Genoese. Four contemporary Genoese chroniclers claim him as a compatriot. Every early map on which his nationality is recorded describes him as Genoese or Ligur, a citizen of the Ligurian Republic. Nobody in the Admiral's lifetime, or for three centuries after, had any doubt about his birthplace.

Paolo Emilio Taviani, in his book Cristoforo Colombo: Genius of the Sea discusses "the public and notarial acts – original copies of which are conserved in the archives of Genoa and Savona – regarding Columbus's father, Columbus himself, his grandfather, and his relatives." In Columbus the Great Adventure he further claims that Columbus named the small island of Saona "to honor Michele da Cuneo, his friend from Savona."^[66]

This is fully accepted by Consuelo Varela Bueno, "Spain's leading authority on the texts, documents, and handwriting of Columbus."^[67] She devotes several pages to the question of Columbus native land, and concludes that "all chroniclers of that period wrote that he was from Liguria in northern Italy."^[68] The evidence supporting the Genoese origin of Columbus is also discussed by Miles H. Davidson. In his book Columbus Then and Now: A Life Reexamined, he writes:^[46]

Diego Méndez, one of his captains, in testimony given in the ''Pleitos'', he said that Columbus was "Genoese, a native of Savona which is a town near Genoa." Those who reject this and the more than ample other contemporary evidence, given by both Italian and Spanish sources as well as by witnesses at these court hearings, are simply flying in the face of overwhelming evidence. [...] What is the reason behind so much futile speculation? It can be mostly attributed to parochialism. Each of the nations and cities mentioned wants to claim him for its own. Since no effort was made to locate the supporting data until the early nineteenth century, and since at that time not all of the archives had been adequately researched, there was, initially, justification for those early efforts to establish who he was and where he came from. To do so today is to fulfill Montaigne's maxim, "No one is exempt from talking non-sense; the misfortune is to do it solemnly."

Language

The spoken language of Genoa and the Ligurian coast would primarily have been Ligurian.^[69] The Italian language was originally based on the fourteenth century vernacular of Florence in the adjacent region of Tuscany, and would not have been the main spoken language of Genoa in the fifteenth century.

Although Columbus wrote almost exclusively in Spanish,^{[nb 23]} there is a small handwritten Genoese gloss in a 1498 Italian (from Venice) edition of Pliny's Natural History that he read after his second voyage to America: this shows Columbus was able to write in Genoese and read Italian.^[70] There is also a note in Italian in his own Book of Prophecies exhibiting, according to historian August Kling, "characteristics of northern Italian humanism in its calligraphy, syntax, and spelling".^{[nb 24]} Phillips and Phillips point out that 500 years ago, the Romance languages had not distanced themselves to the degree they have today. Bartolomé de las Casas in his Historia de las Indias claimed that Columbus did not know Spanish well and that he was not born in Castile.^[71]

Valiant scholars have dedicated themselves to the subject of Christopher Columbus's language.^{[nb 25]} They have conducted in-depth research both on the ship's log and on other writings of his that have come down to the modern day. They have analyzed the words, the terms, and the vocabulary, as well as rather frequent variations often bizarre in style, handwriting, grammar, and syntax. Christopher Columbus's language is Castilian punctuated by noteworthy and frequent Portuguese, Italian, and Genoese influences and elements.^[4]

Other documents

There is a document dated 22 September 1470 in which the criminal judge convicts Domenico Colombo. The conviction is tied to the debt of Domenico — together with his son Christopher (explicitly stated in the document) — toward a certain Girolamo del Porto. In the will dictated by Admiral Christopher Columbus in Valladolid before he died, the authentic and indisputable document which we have today, the dying navigator remembers this old debt, which had evidently not been paid. There is, in addition, the act drawn in Genoa on 25 August 1479 by a notary, Girolamo Ventimiglia.^[72] This act is known as the Assereto document, after the scholar who found it in the State Archives in Genoa in 1904. It involves a lawsuit over a sugar transaction on the Atlantic island Madeira. In it, young Christopher swore that he was a 27-year-old Genoese citizen resident in Portugal and had been hired to represent the Genoese merchants in that transaction. Here was proof that he had relocated to Portugal. It is important to bear in mind that at the time when Assereto traced the document, it would have been impossible to make an acceptable facsimile.^[6] Nowadays, with modern chemical processes, a document can be "manufactured", made to look centuries old if need be, with such skill that it may be difficult to prove it is a fake. In 1960, this was still impossible.^{[6][nb 26]}

In addition to the two documents cited, there are others that confirm the identification of the Genoese Christopher Columbus, son of Domenico, with the admiral of Spain. An act dated 11 October 1496 says:^[73]

Giovanni Colombo of Quinto, Matteo Colombo and Amighetto Colombo, brothers of the late Antonio, in full understanding and knowledge that said Giovanni must go to Spain to see M. Christopher Columbus, Admiral of the King of Spain, and that any expenses that said Giovanni must make in order to see said M. Christopher must be paid by all three of the aforementioned brothers, each one to pay a third ... and to this they hereby agree.

In a fourth notarial act, drawn in Savona on 8 April 1500, Sebastiano Cuneo, heir by half to his father Corrado, requested that Christopher and Giacomo (called Diego), the sons and heirs of Domenico Colombo, be summoned to court and sentenced to pay the price for two lands located in Legine. This document confirms Christoforo and Diego's absence from the Republic of Genoa with these exact words: "dicti conventi sunt absentes ultra Pisas et Niciam."^{[nb 27]}

A fifth notarial act, drawn in Savona on 26 January 1501, is more explicit. A group of Genoese citizens, under oath, said and say, together and separately and in every more valid manner and guise, that Christopher, Bartholomew and Giacomo Columbus, sons and heirs of the aforementioned Domenico, their father, have for a long time been absent from the city and the jurisdiction of Savona, as well as Pisa and Nice in Provence, and that they reside in the area of Spain, as was and is well known.

Finally, there is a sixth document from the notary of Bartolomeo Oddino, drawn in Savona on 30 March 1515. With this notarial act, Leon Pancaldo, the well-known Savonese who would become one of the pilots for Magellan's voyage, sends his own father-in-law in his place as procurator for Diego Columbus, son of Admiral Christopher Columbus. The document demonstrates how the ties, in part economic, of the discoverer's family with Savona survived even his death.

Iberian hypotheses

Crypto-Judaism

Salvador de Madariaga argued in 1940 that Columbus was a marrano forced to leave Spain for Genoa. Scholars such as Jose Erugo, Celso Garcia de la Riega, Otero Sanchez and Nicholas Dias Perez have since concluded that Columbus may have had a Jewish background.^[74] This hypothesis is founded on many observations about Columbus, for example: his reference to the expulsion of the Jews in his first accounts, the reference to the Second Temple of Jerusalem by the Hebraic term "Second House",^[75] the Hebrew letters bet-hei (meaning B'ezrat hashem) on all but one of his letters to his son,^[74] and an anagram that was a cryptic substitute for the Kaddish, according to Cecil Roth.^[74]

Isaac Abravanel, "The Abarbanel" (1437–1508)

Another claimed piece of evidence lies in the fact that many of the personalities who supported Columbus before the kings were of Jewish origin and that his voyage was mainly funded by two Jewish conversos and a prominent Jew: Luis de Santángel, Gabriel Sánchez (treasurer of the Crown of Aragón, d. 1505), and Don Isaac Abarbanel, respectively.^[74][76]

In a 1973 book, Simon Wiesenthal postulated that Columbus was a Sephardi, careful to conceal his Judaism yet also eager to locate a place of refuge for his persecuted countrymen. Wiesenthal argued that Columbus's concept of sailing west to reach the Indies was less the result of geographical theories than of his faith in certain Biblical texts—specifically the Book of Isaiah. He repeatedly cited two verses from that book: "Surely the isles shall wait for me, and the ships of Tarshish first, to bring thy sons from far, their silver and their gold with them," (60:9); and "For behold, I create new heavens and a new earth" (65:17). Wiesenthal claimed that Columbus felt that his voyages had confirmed these prophecies.^[77] Jane Francis Amler shared those views in 1977. Estelle Irizarry echoed this as well, further noting that Columbus always wrote in Spanish, occasionally included Hebrew in his writing, and referenced the Jewish High Holidays in his journal during the first voyage.^[78]

A document suggests that Columbus belonged to a Marrano family from Majorcan origin.^{[citation needed]} However the authenticity of the document hasn't been proved. The novelist Robert Graves argued: "his surname is still common in the island."^[79]

An international study, initiated in 2001 and led by forensic scientist and professor at the University of Granada, José Antonio Lorente, claimed on October 12, 2024, that Christopher Columbus was of Sephardic Jewish origin by examining the DNA in bone fragments of his remains in Seville Cathedral, and matching them with Columbus' two sons buried in the same cathedral, stating that "Both in the 'Y' chromosome and in the mitochondrial chromosome of Ferdinand Columbus there are traits compatible with Jewish origin" and stating that he was likely born somewhere in the Crown of Aragon.^[80][81] However, the study has not been peer-reviewed, as is standard for scientific publishments and publications, and the data on which the conclusion is drawn has not been made available for review by other scientists. In response, many historians dismissed the claim, making reference to the abundance of available sources showing Columbus was from Genoa, Italy.^[82]

A complicating factor of the alleged Jewish origin of Columbus lies in the Alhambra Decree of 1492. King Ferdinand and Queen Isabella from Spain ordered the expulsion of all Jews and the dissolution of Jewish property from their kingdoms. In a matter of months, Spanish Jews were forced to renounce their faith and leave the country, leaving all properties behind.^[83] Columbus was insistent that his ships sail before midnight of the day (3 August, 1492) when the edict of expulsion was to go into effect.^[84]

Catalan

Since the early 20th century, researchers have attempted to connect Columbus to the Catalan-speaking areas of Spain, usually based on linguistic evidence. The first to propose a birthplace under the Crown of Aragon was Peruvian historian Luis Ulloa in a book originally published in 1927 in French.^[85] Antonio Ballesteros Beretta, University of Madrid historian of America, said that Ulloa's "fiery imagination" had placed abstruse interpretations on court documents to support his thesis, had found no positive proof, and had dismissed as false any evidence supporting a Genoese origin.^[86]

Throughout Columbus's life, he referred to himself as Christobal Colom; his contemporaries and family also referred to him as such. This is opposed to the Genoese translation "Cristoffa Corombo", or even the Italian "Cristoforo Colombo". It is possible that Colom is the shortened form of the Italian surname Colombo (which means "dove"), although his surname in Genoese would have been Corombo. Colom can also be a Portuguese, French, or Catalan name, and in the latter means "dove".

Some more recent studies also state Columbus had Catalan origins,^[87] based on his handwriting, though these have been disputed.^{[citation needed]} Charles J. Merrill, a specialist in medieval Catalan literature at Mount St. Mary's University, claims Columbus's handwriting is typical of a native Catalan, and his mistakes in Castilian are "most likely" transfer errors from Catalan, with examples such as "a todo arreo" (a tot arreu), "todo de un golpe" (tot d'un cop), "setcentas" (set-centes), "nombre" (instead of número), "al sol puesto" (el sol post).^[88] Merrill states that the Genoese Cristoforo Colombo was a modest wool carder and cheese merchant with no maritime training and whose age does not match the one of Columbus.^[88] Merrill's book Colom of Catalonia was published in 2008.^[89]

Portugal

A statue of Columbus in Cuba, a town in Southern Portugal

Patrocínio Ribeiro claimed that Columbus was Portuguese in 1916,^[90] and Moisés Bensabat Amzalak hypothesized on Columbus's signature with the Kabbalah. Based on those theories, José Mascarenhas Barreto argued in 1988,^[91] that Columbus was a Portuguese agent who hatched up an elaborate diversion to keep the Spanish from the lucrative trade routes, and suggested he was born in Cuba, Portugal, while his real name was supposedly Salvador Fernandes Zarco.^[92] The Portuguese hypothesis of Zarco from Cuba was further expanded upon in 2008 by Manuel Luciano daSilva and Sylvia Jorge daSilva who included an analysis of Columbus's signature on documents in the Vatican archives.^[93] However, the Zarco genealogy as presented by these authors has been disputed.^{[94][nb 28]}

In his latest book as of 2023, Professor João Paulo Oliveira e Costa, the Chair of the Department of History at NOVA University Lisbon, wrote that it is now "clear the impossibility of Colón having been born into a family of Genoese weavers."^[95] Proponents of the Portuguese hypothesis also point to a court document which stated that Columbus's nationality was "Portuguese"^{[nb 29]} and in another, Columbus uses the words "my homeland" in relation to Portugal.^[97][98]

Other theories

Other theories claim that Columbus was a Byzantine Greek nobleman and the nephew of George Paléologos de Bissipat,^[99] a Sardinian nobleman,^{[100][101][102][103]} a Norwegian of Swedish descent,^[104][105] a Scot,^{[106][107][108]} or that he was the son of King Władysław III of Varna.^[107][108] Many cities have been hypothesized as the birthplace of Columbus, notably Calvi in Corsica, which in Columbus's times was under Genoese rule.^[109][110]

Footnotes

1. A copy of this document, which dates back to the early seventeenth century and had been officially sent from Crown of Castile to the Republic of Genoa, is conserved in the State Archives of Genoa. The supposed original is in the Archivo General de Indias in Seville.
2. De Lollis observes that "the history of this important document is so clear that there is no doubt about its authenticity." Caddeo considers it authentic. Harrisse considers it a forgery from a later period. The Spanish scholar Angel de Altolaguirre considers it authentic. Madariaga states that the majorat "cannot be considered authentic," but adds, however, that it cannot be a complete invention and must have been edited on the basis of the 1502 testament, which has disappeared without a trace. Ballesteros refutes the theory that it is a forgery; the authenticity of the document is proven by the rediscovery of a certificate, dated 28 September 1501, relative to the royal confirmation of the majorat in the archive of Simancas: "After this discovery the authenticity of the institution of the Columbus majorat has been clearly demonstrated and the historical clauses of the document have increased in value, as have Columbus's declarations regarding his Genoese birthplace."^[4] The certificate dated 28 September 1501 is merely a copy of Columbus'1497 royal confirmation of the authorization to institute a majorat and it has none of the text in it that is in the "1598" majorat. Navarrete states that there is no authentic Majorat of 1498, there is only the document presented by Baltazar Colombo which the tribunal rejected.^[5]
3. In May 2006, the Dr. Aldo Agosto, a noted Columbus scholar and state archivist at Genoa, collected one hundred and ten notarial documents, largely unpublished, to be officially presented to the conference of studies in Valladolid. Agosto claims that these documents reconstruct the family tree of Christopher Columbus, going back as far as seven generations.
4. The first nineteen of this book's fifty chapters were published in 1535, the first full version in 1851. This biography of Columbus was translated into Italian by Alfonso de Ulloa and printed for the first time in Venice in 1571.
   Alfonso de Ulloa was a Spaniard born in Caceres in 1529. His father, Francisco, fought for the emperor Charles V and in 1552 came to Venice as a secretary of the Spanish ambassador Diego Hurtado de Mendoza. Ulloa knew Italian so well that he rendered Spanish and Portuguese works into that language. His most famous translation is the Vita dell'Ammiraglio, 1571, "Ferdinand Columbus's life of his father," a book now of priceless value, because the original does not survive. The American historian Washington Irving described the Vita as "an invaluable document, entitled to great faith, and is the corner-stone of the history of the American continent."^[10]
5. In this regard, the eminent Spanish historian Antonio Ballesteros Beretta has written: "One person is responsible for the polemics about the birthplace of Christopher Columbus, and that person is his own son Ferdinand, who, in his biography of his father, displayed ignorance and doubts on a subject which, on the contrary, he should have known well. We must unhesitatingly point out that Don Ferdinand's work is rather tendentious and must be used with great caution. The problem of the Admiral's origin would not exist if Ferdinand had told the truth, which, instead, he deliberately concealed." "His dubious attitude" continues Ballesteros, "about the Discoverer's origins has given rise to an endless series of hypotheses, some of which are farfetched and fantastic. It is true that Ferdinand, in his father's biography, never ventures away from the Italian thesis, but he creates a great confusion. He tries to condition his readers, speaking of a noble family, from which his progenitor was presumably descended. He seeks it in Italy, and his attempts are aimed at creating a kind of nebula in which the splendour of an uncertain birth shines, and at the same time of a definite noble background. What is behind the father's silence and the confusion originated by the son?" Ballesteros has no hesitation in explaining: "We cannot blame Christopher or Ferdinand for having wanted to hide their origins. It was natural and human that Columbus, having reached great heights, at the side of the most powerful sovereigns of the earth, should conceal, with a claim of noble ancestry, his humble origins. Let us try to understand these human weaknesses and let us have compassion on his memory."^[6]
6. The city of Piacenza was part of the Duchy of Milan; the Republic of Genoa was the latter's satellite.
7. Angelo Trevisan, chancellor and secretary to Domenico Pisano, the Venetian Republic's envoy to Spain, writing to Domenico Malipiero, member of Venice's Council of Predagi, notes that "I have succeeded in becoming a great friend of Columbus," and goes on to say: "Christoforo Colombo, Genoese, a tall, well-built man, ruddy, or great creative talent and with a long face."^[6]
8. Gasparo Contarini, Venice's ambassador to the courts of Spain and Portugal, reporting to the Senate of the Venetian Republic on 16 November 1525 on the whereabouts of the island of Hispaniola (Haiti), spoke of the Admiral who was living there. The Admiral was Diego, Christopher's eldest son. Ambassador Contarini describes him thus: "This Admiral is son of the Genoese Columbus and has very great powers, granted to his father."^[6]
9. Though he never appears to have had much to do with Columbus personally, Las Casas knew his son Diego, who provided some information on the early life of Columbus, and also was well acquainted with his natural son, Ferdinand. Las Casas knew both brothers of Columbus, Diego and Bartholomew, "rather well" and gave a succinct description of Bartholomew's person, temperament, and abilities, which demonstrated that he could both observe and describe with economy and distinction. Pedro de Arana, captain of one of the ships Columbus had on his third voyage and brother of Ferdinand Columbus's mother, was another member of the Columbus family group whom Las Casas knew well. He also "held frequent conversations" with Juan Antonio Colombo, a Genoese relative of Columbus, master of a ship on the third voyage.^[13] Thus Las Casas enjoyed such an intimate and, at the same time, so extensive a knowledge of the Columbus family circle and of both printed and manuscript material on the subject, that he was able to write of the Admiral of the Ocean Sea with unequaled familiarity and authority.
10. This map was drawn by Piri Reis, a Turkish cartographer and geographer, known as the nephew of Kemal Reis, in Gelibolu, in the month of muharrem of the year 919 (that is, between the 9th of March and the 7th of April of the year 1513). A large fragment of the map was found in 1929 during work to transform the Topkapı Palace. In 1501 the Turkish seamen engaged in a violent naval battle in the western Mediterranean. They captured a few Spanish cargo ships, in one of which they found various objects and products from America. Piri Reis writes thus in his Bahriye: "On the enemy ships which was captured in the Mediterranean, we found a stone similar to jasper." It was on this occasion that the Turks came into possession of the map that Piri Reis used to trace the coastlines of America. According to the notes made on it, the map was constructed using several other maps as source material. There is no doubt as to its authenticity. In note 5 of the map, here is what Piri Reis tells us, in Ottoman Turkish language: « ... Amma şöyle rivayet ederler kim Cinevizden [from Genoa] bir kâfir [an infidel] adına Qolōnbō [named Columbus] derler imiş, bu yerleri ol bulmuştur ... »^[18] The note goes on to tell how Columbus proposed the enterprise "to the great men of Genoa" and how, on being rejected by them, he turned "to the king of Spain." It continues: "The deceased Gazi Kemal had a Spanish slave who told Kemal Reis he had been three times to that Land along with Columbus." The importance of the testimony on this Turkish map from a time close to that of the discovery lies in the source of the news it carries: a Spanish ship captured by the Turks in 1501. The document is wholly unconnected with contemporary Christian culture and completely autonomous from the above-mentioned references.

15. "Christophorus Colonus quidam ligur vir" or "a certain Christopher Columbus, man of Liguria"
16. Peter Martyr d'Anghiera uses the two words, "Ligurian" and "Genoese", interchangeably. In the first Decade of his De Orbe Novo, book I: "homo ligur". In the second Decade, book I: "Christophorum Colonum ligurem" and book VII: "Christophoro Colono Genuensi" (NRC, VI, 1988).

18. Father Antonio de Aspa mentions that three Genoese merchants helped to finance the venture: Jacopo Di Negro, from Seville, Zapatal, from Jerez, and Luis Doria, from Cadiz. To these names we can add the Genoese merchants Rivarolo, Doria, Castagno and Gaspare Spinola, mentioned by Nuncibay in his Genealogia de la Casa de Portugal, and in Columbus's correspondence with his son Diego. Ballesteros remarks that the only certain thing is that the Italian families of Pinello, Berardi, Centurione, Doria, Spinola, Cattaneo, Di Negro and Rivarolo appear continually in the presence of the great Genoese.^[6]

22. They include the two greatest Columbians in Spain, Antonio Ballesteros Beretta, professor at the University of Madrid, and Juan Manzano Manzano, professor of Seville University; the leading North American authority, Admiral Samuel Eliot Morison; and the Argentinian Diego Luis Molinari, professor at the University of Buenos Aires. Obviously there are many more — admirers and detractors alike — who accept Genoa as his birthplace, including Robertson, Navarrete, Milhou, Irving, Boorstin, Demetrio Ramos, Carpentier, D'Avezac, Manuel Alvar, Nunez Jimenez, Munoz, Peschel, Duro, Mollat, Harrisse, Perez de Tudela, Aynashiya, Morales Padron, Magidovic, Roselly de Lorgues, Asensio, Braudel, Winsor, Fiske, Ciroanescu, Ruge, Markham, Serrano y Sanz, Obregon, Laguarda Trias, Thacher, de Gandia, Emiliano Jos, Aurelio Tio, Goldemberg, Vignaud, Ramirez Corria, Alvarez Pedroso, Marta Sanguinetti, Altolaguirre, Breuer, Leithaus, Alegria, Arciniegas, Davey, Nunn, Johnson, Juan Gil, Sumien, Charcot, Ballesteros Gaibrois, Levillier, Dickey, Parry, Young, Streicher, de La Ronciere, Muro Orejon, Pedroso, Brebner, Houben, Rumeu de Armas, de Madariaga, Stefansson, Martinez Hidalgo, Taylor, Mahn Lot, Consuelo Varela, Verlinden, Bradford, Heers, Davidson,^[46] Bergreen,^[60] Fernandez-Armesto,^[61] McGovern,^[62] Kirkpatrick Sale,^[63] William and Carla Phillips.^[64] Among the leading Italian authorities on Columbus, who also concur, are Spotorno, Sanguineti, Tarducci, Peragallo, Desimoni, De Lollis, Salvagnini, Uzielli, Assereto, Pessagno, Caddeo, Magnaghi, Almagia, Revelli and Bignardelli. Among the famous historians and geographers who have written general works that make reference to Columbus's Genoese birth, we will mention only Humboldt, the great 19th-century German geographer; Burckhardt, author of the prestigious Civilization of the Renaissance in Italy; Fisher, the distinguished English historian; Pirenne, the eminent Belgian historian; Merzbacher, professor of History of Law at the University of Innsbruck; and Konetzke, professor of Iberian and Latin-American History at Cologne University.^[6]
    The eminent Italian historian, Paolo Emilio Taviani, devoted his time to the study of Christopher Columbus, becoming "one of the world's leading authorities on the subject. He retraced the voyages of the Genoese navigator and wrote numerous books about his life and times. Taviani, who was made a life senator in 1991, donated his collection of 2,500 volumes on Columbus to a council-owned library in his native Genoa."^[65]
23. The oldest fragment of writing certainly attributable to Columbus is a marginal note in one of his books. De Lollis dates it around 1481. It is written in bad Spanish, mixed with Portuguese. All Columbus's letters, even those addressed to Genoese friends and to the Bank of Saint George, are written in Castilian.^[6]
24. De Lollis claims that Columbus wrote these notes in Italian because of his deep bitterness, at that time, against the Spanish court. Ballesteros advances a more logical theory, suggesting that this is the psychological reaction of an elderly man, nostalgic for his homeland. Surely Columbus would never have written in Italian if he had not been in such close touch with many compatriots, first in Portugal, then in Spain and finally during his voyages of discovery. It is generally accepted that he was on friendly terms with Genoese, Tuscans, Corsicans, Venetians and Neapolitans, and the point has been especially underlined by historians.^[6]
25. Chief among them are Menéndez Pidal, Arce, Caraci, Chiareno, Juan Gil, Milano, Consuelo Varela.^[4]
26. In light of the two acts cited, the tendency to compare, or worse, to confuse or replace the true "Genoese" Columbus family with other similarly named Ligurian, Lombard or foreign families collapses, as does the main argument of the dilettantes who oppose the Genoese documentation and try to maintain that there was indeed a Genoese Christopher Columbus, woolen-weaver, but who was not the discoverer of America.
27. "The summoned parties are absent and beyond Pisa and Nice."
28. In this regard, the American historian Samuel Eliot Morison writes: "If, however, you suppose that these facts would settle the matter, you fortunately know little of the so-called "literature" on the "Columbus Question." By presenting farfetched hypotheses and sly innuendos as facts, by attacking documents of proven authenticity as false, by fabricating others (such as the famous Pontevedra documents), and drawing unwarranted deductions from things that Columbus said or did, he has been presented as Castilian, Catalan, Corsican, Majorcan, Portuguese, French, German, English, Greek, and Armenian."^[25]
29. The document describes the person as Portuguese but his name is empty. However, Antonio Rumeo De Armas in his book identifies the person, whose name is omitted, as Christopher Columbus by matching it with the payment receipt in Alonso de Quintanilla's ledgers. Rumeu de Armas thinks Columbus was Genoese but so influenced by his years in Portugal that he could have been mistaken for a Portuguese by Spaniards.^[96]
