Roland is one of three operas by composer Jean-Baptiste Lully and librettist Philippe Quinault based on the medieval legends of chivalry (the other two are Amadis and Armide). Roland sets episodes from Ludovico Ariosto's Orlando furioso. And, like its sibling Armide, Roland centers on the conflict between duty and love. Acts I-III portray this conflict within Angélique, Queen of Cathay, while the remaining acts concern Roland's unrequited love for Angélique, which is resolved only when the goddesses Glory and Fame show him that this too is a struggle between duty and love.
