Deusdedit Hypatos (†755) (also Deusdatus, Diodato, or Teodato Ipato) was the 4th doge of Venice, from 742 to 755, and son of Ursus Hypatos. He also served at the third magister militum in 739.
Where were the doges of Venice buried? A little bit all over, in churches and monasteries in Venice and beyond.
