In the middle of the 17th century this triptych, known as the Middelburg Altarpiece, was in the Flemish city of Middelburg, founded by the rich Bruges burgher Pieter Bladelin and his wife around 1444. The donor of the work, also known as the Bladelin Altarpiece, is therefore usually thought to have been the founder of the city himself. On the other hand, Middelburg passed into other hands after the death of the Bladelins, who had no children, and there is no evidence that the altarpiece did not arrive there at a later date. Furthermore, it shows only one donor, although Bladelin's wife was cofounder with him of the new city. The donor depicted, wearing the same fashions as the Duke of Burgundy and obviously a member of the upper classes, must therefore be considered unidentified.
