Which of the songs was composed by Franciscus Bossinensis, or Francis of Bosnia?

I believe the correct answer is: Se mai per maraviglia.

Franciscus Bossinensis (also known as Francis the Bosnian) was a lutenist-composer active in Venice, Italy in the 15th century. Franciscus published song "Se mai per maraviglia" (translated as "If ever in wonder") and two collections of lute music, printed by the Venetian printing house of Ottaviano Petrucci.
