Perhaps a native of the Vermandois region of Picardy, he was a singer at Milan Cathedral in 1459, remaining there until December 1472. By July 1474 he was one of the 'cantori di capella' in the chapel of Galeazzo Maria Sforza. Between 1476 and 1504 he passed into the service of Cardinal Ascanio Sforza, whom he probably accompanied in Rome in 1484. His name first appears among the papal chapel choi
