Deusdedi: John the Deacon, Cron. Ven., p. 95. Deusdedit: elsewhere.

Son of Ursus (Oursos 3): John the Deacon, Cron. Ven., pp. 95, 97. He was third of the magistri militum who governed Venetia for a few years in the mid eighth century; he succeeded Felix 7; the Chronicon Altinate says that he governed for two years, John the Deacon for one: Chron. Alt., p. 115 ("Deusdedit magister militum sedit ann. II"), John the Deacon, Cron. Ven., p. 95 ("exinde tercius magister militum vocitabatur Deusdedi, filius sepedicti Ursonis interfecti ducis, qui etiam unius anni spatio illius potestatis fuerat"). He was succeeded as magister militum by Ioubianos 2. Hypatos et dux (i.e. Venetiae); he succeeded the last magister militum, Ioannes 436, and governed Venetia as dux for thirteen years: Chron. Alt., p. 116 ("Deusdedit ypatus et dux ducavit ann. XIII"). The title of hypatos indicates the close links still enduring between Venetia and Byzantium. According to John the Deacon, two years after Deusdedit 3 held office as magister militum, the Venetici reverted to government by duces and chose Deusdedit 3 on the island of Malamocco; he ruled them for thirteen years: John the Deacon, Cron. Ven., p. 97 ("eisdem etiam diebus Venetici, magistrorum militum prelibate prefecture dignitatem abominantes, rursum, ut quondam, ducem, videlicet Deusdedem, sepedicti Ursonis ypati filium, in Metamaucense insula sibi crearunt, cuius regimen extitit spatio annis XIII"). He built the stronghold of Brundulus ("castrum quod Brundulus dicitur"), and it was there that he was attacked and blinded by Galla 1, who succeeded him as dux: John the Deacon, Cron. Ven., p. 98.
