Cranach the Elder ranks among the most significant German Renaissance painters, along with masters such as Albrecht Durer. Friendship united the painter with the Protestant Reformers at a very early period; yet it is difficult to fix the time of his first acquaintance with Luther. The oldest reference to Cranach in the Reformer's correspondence dates from 1520.
I have never heard about Cranach before the news of the stolen painting, and I am not very interested in religious motives. I have though through Wikipedia found that he also made other motives and this one may be in contrast to the one stolen (or maybe the same in a different context)Werwolf from 1512.
