Marino Zeno

Nothing is known of Marino Zeno's early life, before his election in May 1205 as the Venetian Podestà of Constantinople, in the aftermath of the capture of Constantinople by the Fourth Crusade in 1204 and the death of Doge Enrico Dandolo in the city. He remained in office until May 1207, when his successor, Ottaviano Querini, arrived in Constantinople and Zeno returned to Venice.^[1]

Zeno is next attested in 1217, when he witnessed the affirmation of Venetian privileges by the new Latin Emperor, Peter of Courtenay at Rome.^[2] In the next year, Zeno served as ducal councillor, a post he held again in 1224/25 and 1226/27, along with judgeships in Venice in 1226 and 1228.^[2]
