The Missa Fors seulement is built on the chansons by Antoine de Févin and Matthaeus Pipelare; the Missa Fit porta Christi pervia is based on a plainchant cantus firmus; the Missa Myns liefkens bruyn ooghen uses as its source a secular song in Dutch, by Benedictus Appenzeller; and the Missa Stabat mater uses the motet by Josquin, a composer he evidently admired.
