Jacobus Clemens non Papa (also Jacques Clément or Jacob Clemens non Papa) (c. 1510 to 1515 – 1555 or 1556) was a Netherlandish composer of the Renaissance based for most of his life in Flanders.[1] He was a prolific composer in many of the current styles, and was especially famous for his polyphonic settings of the psalms in Dutch known as the Souterliedekens.[2]
