The Madrid panel was in a Belgian private collection and not widely known about until 1957. The panels were first exhibited alongside each other at the National Gallery, London, in 1961.[1] The panels are considered of equal quality and by the same hand, i.e. one is not a workshop copy of the other. However, the existence of two near identical paintings from such an early and renowned master has excited art historians as to their commission, dating, and providence.
The portraits are renowned for their close and realistic observation of the subject's features. They lack any attempt at flattery or idealisation, instead the sitter is depicted as he probably was; overweight, with a long, straight nose and pronounced nostrils and a "fleshy, unbecoming gaze".[3] However the portrait cannot be viewed as satire, mocking or judgmental. The man has an alert appearance and intelligent, reasoned eyes, and the close cropping against a light coloured background seems deliberate, probably intended to convey the weight of his personal presence and charisma.
The sitter's identification as Robert de Masmines (c. 1387–1430/1), a Burgundianknight and governor of the County of Hainaut, was suggested by Georges Hulin de Loo, based on the man's similarity to a named portrait attributed to Jacques Leboucz from the 16th-century Recueil d'Arras manuscript. However, this theory is neither conclusive nor widely accepted.[1]
