Peire de Corbiac or Corbian was a Gascon cleric and troubadour of the thirteenth century. His most famous works are a religious piece, the Prière à la Vierge (prayer to the Virgin), and his "treasures", Lo tezaurs (c. 1225).^[1]

Peire was born at Corbiac near Bordeaux to a poor family.^[2] He was educated at Orléans in the Scholastic tradition.^[3] His nephew was the troubadour Aimeric de Belenoi, whose vida refers to him as maestre (master, teacher) and Peire elsewhere calls himself maistre. Certainly Peire's Tezaur is didactic in nature: his purpose in writing was to convince the wise that though he was poor in material terms he was richer still. Composed in 840 alexandrines, the Tezaur is an encyclopaedic compilation of all that the troubadour knew.^[2] The work displays a great breadth of knowledge. He expends 547 lines narrating the chief events of the Old and New Testaments, then discusses the seven liberal arts, medicine, surgery, necromancy, mythology, the lives of the ancient Greeks and Romans, and those of the contemporary French and English.

Peire was familiar with the work of Venerable Bede, of John de Holywood, and of Chrétien de Troyes.^[4] He also provides the modern historian with several pieces of crucial information not found elsewhere. He refers to dancing the Sanctus, Agnus, and the Cunctipotens, showing that the liturgy was performed.^[3] The Tezaur also contains the first mention of contrapointamens, a century before its appearance in Latin as contrapunctus, today's counterpoint.^[3] The Tezaur had a lasting influence in the Late Middle Ages. The Jew Emanuele da Roma wrote the Ninth Meḥabbereth, a Hebrew poem based on the Tesoretto of Brunetto Latini, itself based on the Tezaur of Peire.^[5]

Peire was a religious man, as the dedicatory first verse of his Tezaur attests: it contains a dedication to Jesus and Mary and a statement of Trinitarian faith:
