a Man (Self Portrait?) and the figure in the background of the Madonna with Chancellor Rolin). A dog is an early form of the breed now known as the Brussels griffon. The painting is signed, inscribed and dated on the wall above the mirror: "Johannes de eyck fuit hic 1434" ("Jan van Eyck was here 1434"). The inscription looks as if it were painted in large letters on the wall, as was done with proverbs and other phrases at this period. Other surviving van Eyck signatures are painted in trompe-l'œil on the wooden frame of his paintings, so that they appear to have been carved in the wood. Identity of subjects In their book published in 1857, Crowe and Cavalcaselle were the first to link the double portrait with the early 16th century inventories of Margaret of Austria. They suggested that the painting showed portraits of Giovanni [di Arrigo] Arnolfini and his wife. Four years later James Weale published a book in which he agreed with this analysis and identified Giovanni's wife as Jeanne (or Giovanna) Cenami. For the next century most art historians accepted that the painting was a double portrait of Giovanni di Arrigo Arnolfini and his wife Jeanne Cenami but a chance discovery published in 1997 established that they were married in 1447, thirteen years after the date on the painting and six years after van Eyck's death. It is now believed that the subject is either Giovanni di Arrigo or his cousin, Giovanni di Nicolao Arnolfini, and a wife of either one of them. This is either an undocumented first wife of Giovanni di Arrigo or a second wife of Giovanni di Nicolao, or, according to a recent proposal, Giovanni di Nicolao's first wife Costanza Trenta, who had died perhaps in childbirth by February 1433. In the latter case, this would make the painting partly an unusual memorial portrait, showing one living and one dead person. Details such as the snuffed candle above the woman, the scenes after Christ's death on her side of the background roundel, and the black garb of the man, support this view. Both Giovanni di Arrigo and Giovanni di Nicolao Arnolfini were Italian merchants, originally from Lucca, but resident in Bruges since at least 1419. The man in this painting is the subject of a further portrait by van Eyck in the Gemäldegalerie, Berlin, leading to speculation he was a friend
