Arnaut Vidal de Castelnou d'Ari
Arnaut Vidal de Castelnou d'Ari was a medieval Occitan author from Castelnaudary.
Arnaut was a troubadour and the first poet laureate of the Consistori del Gay Saber. Arnaut's poem in praise of the Virgin Mary was adjudged the best by the Consistori at a contest held on Holy Cross Day 1324 at Toulouse and the troubadour was awarded the violeta d'or. He received the flor de gaug d'argen fi as the first prize for a dansa at the festa de Santa Crotz on 3 May 1324.
He was also the author of the chivalric romance Guilhem de la Barra, of which Paul Meyer produced the editio princeps. A new edition has since been produced.
