The most famous work of art here is Michelangelo's Moses (c.1513-15), in the central position. The patriarch is shown having just sat down to teach after bringing the Tablets of the Law down from his interview with God on Mount Sinai. The little horns on his head are a result of an early mistranslation of the Hebrew, in which the word for "rays of light" was rendered as "horns". It is said that in good light and from the correct angle, it is possible to see portraits of Michelangelo and Julius II in Moses' beard.
