Matfre Ermengau

Matfre Ermengau was a Franciscan friar, legist, and troubadour from Béziers. He had a master of laws degree.He wrote one canso, whose melody survives, and one moralising sirventes. His most famous work was an Occitan poetic book in 35,600 octosyllables called the Breviari d'amor, begun in 1288. Encyclopedic in length and diversity, its sole purpose is the reconciliation of love for God with the erotic amours of the troubadour lyric. It is divided into parts and is structured like a "tree of love". The Breviari is preserved in twelve full codices and as many fragments. It was translated into Castilian and the Limousin dialect. Matfre also says that he would have written better in Latin.

The work begins with popular theology, a section entitled "The Study of God and the Creation". From the Trinity it moves to angels, demons, then the zodiac and the planets.
