Ammiana was a medieval Venetian settlement, located north of Torcello, around the island of Santa Cristina.
The lagoon was settled in Antiquity, and in the 600s, there were numerous known towns, and several important cities. Venice, however, was not one of them.
Translation of the parts related to Venice of the “De Administrando Imperio” (c.950) by Constantine VII Porphyrogenitus.
Where were the doges of Venice buried? A little bit all over, in churches and monasteries in Venice and beyond.
