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.
