 He also wrote several hymns, four of which survive in today's German Protestant hymnals.He is, however, of greater importance as a source for other hymn-writers.His "Meditationes Sanctorum Patrum", a bipartite collection of prayers purportedly based on writings of Augustine, Bernard of Clairvaux and Anselm of Canterbury (though actually these texts were probably pseudo-Augustinian and -Bernardian, written much later in the style of the Church Fathers), provided Johann Heermann with a basis for many of the hymns in his "Devoti musica cordis".
