Tommaso Tommasini (Croatian: Toma Tomasini; died in early 1463), better known as Thomas of Hvar (Croatian: Toma Hvarski), was Bishop of Lesina (Hvar) from 23 December 1429 until his death, as well as permanent papal legate to the Kingdom of Bosnia from 1439 until 1461.
[1] Thomas was Venetian by birth, but he "must have known Slavic" both through his episcopate on the Croat-inhabited island and through his prolonged contact with Bosnians.
He significantly influenced the relations between the Holy See and Bosnia, as well as papal views on the indigenous Bosnian Church.
John Van Antwerp Fine, Jr. argues that Thomas deliberately misinformed the Papacy about the Bosnian Church, fabricating claims of dualism.
He probably discussed the Catholic Church's issue with heresy in Bosnia at that time.
