Willem Adriaensz. Key (Breda c. 1515/6-1568 Antwerp)

The attribution to Willem Key was first proposed by Dr. Gustav Glück as noted by Borenius in his article of 1942 (loc. cit.). Borenius proposed that the sitter might be Philippe II de Croÿ, Seigneur de Croÿ, Count of Porcéan and 1st Duke of Aarschot (1496-1549), on the basis of the coat-of-arms at the upper left of the portrait. Acknowledging that he did not have up-to-date biographical information for the Duke, Borenius could not have been aware that he would have been 51, not 56, in 1547. We are grateful to Mr. Jan van Helmont for confirming that these are indeed the de Croÿ arms, and for pointing out that the sitter is actually Robert de Croÿ, Duke-Bishop of Cambrai, who participated in the Council of Trent in 1546-7, publishing an account of it in 1551, and whose funerary monument is extant in the cathedral at Cambrai. A drawing related to this portrait appears in the Recueil d'Arras (Châtelet and Paviot, loc. cit.), and a medal which may be based on it is recorded as having been in the collection of Wilhelm Itzinger, Berlin.
