Opening illustration from the French poem La Livre de la Deablerie by Eloy D’Amerval, composer and priest (1455-1508). This poem is a lengthy Christian lyrical work about the activities of Satan, his semi-competitor and former pupil Lucifer, and especially how they try to influence people to sin. He worked under the famous master Guillaume Du Fay, however sadly none of his music seems to have survived to today except a 5-voice mass, Missa Dixerunt Discipuli.
