E fo meiller trobaire que negus d'aquels qu'eron estat denan ni foron après lui; per que fo apellatz maestre dels trobadors, et es ancar per totz aquels que ben entendon subtils ditz ni ben pauzatz d'amor e de sen.
He was the best troubadour of those who lived before him or came after him, and for that reason was called the master of the troubadours, a title which is still applied to him in the opinion of those who know something about poetry and love.
