Marcello Tegalliano

Marcello Tegalliano was, according to Venetian chronicler John the Deacon and some other, much later sources and traditions, the second Doge of Venice, serving (allegedly) from 717 to 726. Since he is not known as such from contemporary sources, modern scholars have raised various questions regarding his personal (prosopographical) historicity and reliability of later accounts, provided by John the Deacon, who died sometime after 1018.
