Raimon de Cornet was a fourteenth-century Toulousainpriest, friar, grammarian, poet, and troubadour. He was a prolific author of verse; more than forty of his poems survive, most in Occitan but two in Latin. He also wrote letters, a didactic poem, a grammar, and some treatises on computation. He was the "last of the troubadours" and represented l'esprit le plus brillant of the "Toulousain School". He appears in contemporary documents with the titles En and Frare. Raimon's magnum opus is his Doctrinal de trobarcomposed around 1324 and dedicated to Peter IV of Aragon. The Doctrinal follows the grammar put forward later by the Consistori del Gay Saber of Guilhem Molinier and it is structurally identical to Guilhem's Leys d'Amors. Both works spend a good deal of space quoting illustrative passages from the greatest troubadours of the past. The Doctrinal is considered the first work of the Gay Saber tradition. In a passage praising the pleasure of poetry, Raimon lists many of the traditional genres, which he and others like him had helped to define: Raimon strongly supported the Crusaders and bitterly opposed the clergy, Avignon Papacy, and eventually Philip VI of France. He wrote two "Crusade songs". The earlier one was composed in 1332, when Philip VI announced his intention of going on Crusade in July. Raimon suggests that the king should impose a tax on those men who do not join the Crusade, and in any case those who remain in France should pray two or three times daily for those who do go to the Holy Land. He notes that missionaries will inevitably accompany the host and attempt to convert the "Saracens". The second song, composed in 1336, is an attack on Philip for not completing his promised Crusade. Raimon's poem Quar mot orne fan vers contains the earliest reference to basse danse. In describing the profession of the jongleurs he notes that they rapidly pick up the bassas dansas. This reference predates any other by a century. Eighteen of Raimon's lyric poems are preserved in the final, unfinished folios of the Cançoner Gil, known as troubadour MSSg or Z, now MS 146 in the Biblioteca de Catalunya in Barcelona. In 1341, possibly in Raimon's lifetime, the Catalan poet Joan de Castellnou wrote a Glosari al Doctrinal de Ramon de Cornet, a gloss on the Doctrinal.
