Giovanni e Paolo at Venice was destroyed by a fire on 16 August, 1867. But there are exquisite paintings of the scene by Lorenzo Lotto and Bellini. S. Peter, whose shrine is in San Eustorgio, Milan, was canonized 25 March, 1253, by Innocent IV. Major Feast, 29 April. [41] Muratori. _Antiquitates italicæ medii æui_, Milan, 1738-42.
