Paolo Lucio Anafesto

Paolo Lucio Anafesto (Latin: Paulucius Anafestus) was, according to Venetian chronicler John the Deacon and other later traditions, the first Doge of Venice, serving (allegedly) from 697 to 717. Since he is not known from contemporary sources, various scholars have raised several questions regarding his personal (prosopographical) historicity and reliability of late accounts, provided by John the Deacon, who died sometime after 1018.
