 13th-century composer, theorist, and scholar, Petrus de Cruce was apparently born in or near Amiens, in north-central France; for dates we know only that he was active in the years around 1290.He held the title of "magistar," indicating that he probably studied at the University of Paris.Given the overlap of their lives and supposed tenures at Paris, Petrus may have been Franco of Cologne's student.
