The Madonna of Nicolas van Maelbeke was a large but now lost hinged triptych attributed to Jan van Eyck, thought to have been completed late in his career, perhaps his final work. It is known today through a replica dating to 1757–60, and several near contemporary silverpoint copies, one by Petrus Christus or his workshop c. 1445 in Vienna, and another by an unknown artist, probably a member of his workshop, which is now in the Germanisches Nationalmuseum in Nuremberg. The original was commissioned by Nicolas Maelbeke for the Saint Martin monastery in Ypres where it was installed in 1445. That the donor is present in the central panel is unusual; typically in mid-15th century triptychs he or she would be in an accompanying wing.
