"Bishop of Ravenna in Italy from 452 to 494. He saved his flock from the fury of Attila the Hun and mitigated its lot when the city was taken by Theodoric, King of the Ostrogoths."[20]Andreas Agnellus lists only one bishop of Ravenna with this name in the 5th century. Although Agnellus mistakenly assigns events dated to the earlier part of the century to John's office, John's surviving epitaph (CIL 11, 304) states he was bishop 16 Years, ten months and 18 days, and was buried 5 June 494.

The holy icon of "Panagia Mesopantitissis" was brought to Crete from Constantinople during the Iconoclastic period, in order to save it from the impious fury of the iconoclasts. According to Holy Tradition it was painted by St. Luke the Apostle. During the period of Venetian rule in Crete, it was kept in the Temple of the Holy Apostle Titus in Heraklion. Every Tuesday pious Christians prayed a litany before the holy icon. When Heraklion was captured by the Hagarenes, the Venetians took the venerable icon of the Virgin Mary and transferred it to Venice, where they placed it in the Church of the Most Holy Theotokos of the Salutations, where it has been kept there until today. A copy of the Holy Icon can be found in the Church of the Holy Apostle Titus in Heraklion, where the feast of the Synaxis of this icons is celebrated.
