 According to an account by Claude Hémeré, a friend and librarian of Cardinal Richelieu whose evidence dates as late as 1633, and who used the records of the collegiate church of Saint-Quentin, Josquin became a choirboy with his friend and colleague the Franco Flemish composer Jean Mouton at Saint-Quentin's royal church, probably around 1460.Doubt has been cast on the accuracy of Hémeré's account, however.Josquin may have studied counterpoint under Ockeghem, whom he greatly admired throughout his life
