What is "peirol"

Peirol or Peiròl (, ; birth ca. 1160, known in 1188–1222/1225, death in the 1220s) was an Auvergnat troubadour who wrote mostly cansos of courtly love in the late twelfth and early thirteenth centuries. Thirty-four surviving poems written in Occitan have been attributed to him; of these, seventeen (sixteen of them love songs) have surviving melodies. He is sometimes called Peirol d'Auvergne or Peiròl d'Auvèrnha, and erroneously Pierol.
