vidame, vicedominus) was the representative of the Republic of Venice in the city of Ferrara from the late 13th century until 1509.
[1] By the 15th century, the Venetians regarded the visdomino as possessing a customary right to seize contraband.
This had its origins in a treaty of 1240 that forbade Ferrara from receiving merchandise direct from the sea.
[2] The public authority of the visdomino was finally regularized in the treaty of 1455 between Venice and the Duchy of Ferrara.
[3] After Venice was defeated in the battle of Agnadello on 14 May 1509, Duke Alfonso d'Este expelled the visdomino permanently.
