8284 Cranach           Discovered 1991 Oct. 8 by F. Borngen at Tautenburg.
Named in honor of the German painter, draftsman and copper engraver Lucas Cranach the Elder (1472-1553). As a friend of Luther and Melanchthon, he is reputed to be the primary master of the German Reformation period. His first work is ascertainable in Vienna; beginning in 1505, he was an esteemed court painter for the elector of Saxony Friedrich der Weise in Wittenberg. One of his best-known works is the altarpiece in the main church of Weimar, which was completed by his son Lucas Cranach the Younger.
