Johannes de Galonifontibus was a Dominican friar active in the South Caucasus in March 1377.[1] He was appointed by Gregory XI on 9 March 1377 as Bishop of Nakhchivan. He is often mistaken for Archbishop of Sultaniya, John III of Soltaniyeh who was also a bishop of Nakhchivan because of Anton Kern, who published John III's Libellus de Notitia Orbis and tentatively associated him with his namesake.[2]
