Marcello Tegalliano (Latin "Marcellus") was the second Doge of Venice (717-726) according to tradition. He was probably the "magister militum" of the first doge, Paoluccio Anafesto. However, even Paoluccio's position is unclear and Marcello is probably a mistake for Marcellus, the "magister militum" of Paul, Exarch of Ravenna. Wikipedia
