Lucas Cranach was a German Renaissance artist whose paintings and woodcuts are pretty amazing (Caution, you will find some nude painting and woodcuts in his collection). He was a friend of Martin Luther, was present at his wedding to Katherina von Bora, and was the godfather to their first child, Johannes "Hans" Luther. I recently came across this woodcut, and then the painting of Cranach's "Law and Grace." I have spent a good amount of time just pouring over the details, and thought you would enjoy it as well.
