Patriarch ANIANUS (THE COBBLER)
Tradition says that the Apostle Mark‘s first convert in Alexandria was Anianus the cobbler. Mark later consecrated Anianus as the first bishop of the new church. Eusebius of Caesarea was the first author to mention the story of the succession of Mark in his book Church History.
This tradition is developed in later sources such as the History of the Patriarchs and the Coptic Synaxarion to include many details. Unfortunately the entire Coptic version of the History of the Patriarchs did not survive; hence, we do not know exactly the origin of this story. Anianus is commemorated in the Coptic calendar on the 20th Hathor. According to Western tradition, the relics of Anianus were transferred to Venice in the 12th century.
