Dubois de Groër considers the prototype for this panel to be De Lyon's portrait of the same sitter in the Louvre (op. cit., no. 116), and describes this picture as 'une excellente réplique, de la main de Corneille pour la majeure partie, sinon pour l'ensemble'. With its stronger modelling of the face, the presence of underdrawing and the more detailed costume, the present picture seems to call into question the primacy of the Louvre picture. De Groër lists two other versions, both at the musée du château, Versailles (ibid., nos. 116 B-C). A further version was sold in these Rooms, 14 May 1971, lot 29. De Groër dates the Louvre picture to circa 1550-55.
Charles de la Rochefoucauld, comte de Randan (1525-1562) was the third son of comte François II de la Rochefoucauld and Anne de Polignac. He became colonel genéral de l'infanterie and served under the King in several battles. After the Battle of Metz in 1552, he was sent to England as Ambassador and negotiated peace with Scotland. He returned to France and played an important role in the Sieges of Bourges and Rouen, at which he was fatally wounded.
