Minos, a detail of the Last Judgment, by Michelangelo a Wikigallery public domain photo here
This is one of the few portraits Michelangelo ever painted. Who is it? Biagio da Cesena, the papal master of ceremonies. He is the devil Minos here in the Last Judgment picture on the Sistine Chapel wall.
Minos stood at the Gates of Hell just as St. Peter stood at the other ones. He examined the curriculum of the damned and decided where to send them—to which department.
Why did Michelangelo piant Biagio as a devil?
Biagio told Pope Julius within Michelangelo’s hearing that the big painting, with all its nudes, would be more fitting for a tavern wall than a chapel. In revenge Michelangelo put Biagio’s face on Minos.
