His most notable work is Leys d'amors ("Laws of Love"), a treatise on rhetoric and grammar that achieved great notoriety and, beyond the Occitan, influenced poets writing in Catalan as well as in Galician or Italian, for which they served as a reference.
The consistory consisted of seven members who organized poetic contests and rewarded lyric poems that best imitated the style of the 12th- and 13th-century troubadours.
Molinier was not an original member of the consistory, but he was its chancellor in 1348, when he was tasked with codifying the principles of Occitan lyric poetry.
The archives of the present-day Académie des Jeux floraux (a descendant of the Consistory del Gay Saber) contains a folio copy of this edition under the title by which the work has become known.
[1] The Leys d'amors owes a debt to Brunetto Latini's Li livres dou Tresor and Albertano di Brescia's Ars loquendi et tacendi.
