(Lat. bajulus or baillivus; cf. Ital. balio, Fr. bailli, Eng. bailiff), in diplomacy, the title borne by the Venetian representative at Constantinople. His functions were originally in the nature of those of a consul-general, but from the 16th century onwards he had also the rank and functions of a diplomatic agent of the first class. "Under the name of bayle," says A. de Wicquefort, "he performs also the functions of consul and judge; not only between members of his own nation, but also between all the other merchants who trade in the Levant under the flag of St Mark."
