Peire de Corbiac
troubadour
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).
Peire was familiar with the work of Venerable Bede, of John de Holywood, and of Chrétien de Troyes. 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. The Tezaur also contains the first mention of contrapointamens, a century before its appearance in Latin as contrapunctus, today's counterpoint. 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.
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:
