S. Pietro in Vincoli
was founded about 442, as the receptacle for the chains of St. Peter, which had been presented by Eudoxia, wife of Valentinian III., to Pope Leo I. This church contains the famous statue of Moses with horns, by Michael Angelo. Mediaeval Christian artists generally represented Moses with horns, owing to an erroneous translation of Exodus XXXIV., 35. Michael Angelo represented these horns upon the head of Moses as having been about three inches in length.
