In the Eastern Orthodox Church, November 25th is the feast day of St. Catherine of Alexandria, who converted hundreds of Egyptians to Christianity in the 3rd century before being beheaded at the age of 18. The legend of her martyrdom may now be disputed, but 1100 years after her death she appeared in a vision to St. Joan of Arc, and for centuries after that she was still inspiring great artists like Luini. I love this subtle masterpiece. It radiates a quiet charisma and embodies the enduring power of myth. Click to enlarge.
