Marcello Tegalliano (†726) was, according to tradition, the 2nd doge of Venice from 717 to his death in 726, but very little is known about him.
The account of the election of the first three doges of Venice (Pauluccio, Marcello and Orso), from the “Istoria Veneticorum” by John the Deacon.
Where were the doges of Venice buried? A little bit all over, in churches and monasteries in Venice and beyond.
