The marble monument is by Antonio Canova (1757–1822), the most celebrated Italian sculptor of his day. It was erected in 1819.
Description
The monument takes the form of a truncated obelisk. It carries bas relief profile portraits of the three exiled princes, and the following inscription:
("To James III, son of King James II of Great Britain, to Charles Edward and to Henry, Dean of the Cardinal Fathers, sons of James III, the last of the Royal House of Stuart. 1819")
Below the inscription are two weeping angels, symbolising the lost hopes of the exiled Stuarts.
The monument to the Royal Stuarts was originally commissioned by Monsignor Angelo Cesarini, executor of the estate of Henry Benedict Stuart. Among the subscribers, curiously, was King George IV, who (once the Jacobite threat to his throne had ended with the death of Cardinal Stuart in 1807) was an admirer of the Stuart legend.[1]
The monument stands towards the back of the basilica in the left aisle opposite the door from which people coming down the spiral staircase from the dome and roof exit. It is frequently adorned with flowers by Jacobite romantics.
Until 1938 the bodies of the three Stuarts were buried where the tomb of Pius XI now stands. In that year the bodies were moved slightly further east on the left side of the crypt, to make room for Pius's tomb. In 1939 a single sarcophagus was erected over the three graves. On top of the sarcophagus is a bronze pillow on which is placed a bronze crown. On the front of the sarcophagus is the same inscription quoted above.
MARIA CLEMENTINA M. BRITANN. FRANC. ET HIBERN. REGINA
("Maria Clementina, Queen of Great Britain, France and Ireland"[a])
Queen Christina of Sweden, the only other monarch with a memorial in the church, also lies entombed in the crypt below the basilica, with the Royal Stuarts. She abdicated her throne in 1654 to convert to Catholicism.
