From the LCMS website:
Lucas Cranach (1472-1557), a close friend of Martin Luther, was a celebrated painter of portraits and altar pieces and a producer of woodcuts of religious subjects. Albrecht Duerer (1471-1528), a native of Nuernberg, Germany, was one of the most learned of Renaissance artists and also an ardent admirer of Martin Luther. His paintings and woodcuts include examples of the splendor of creation and skilled portrayals of biblical narratives. Both Cranach and Duerer are remembered and honored for the grandeur of their works of art that depict the glory and majesty and the grace and mercy of the triune God.
