Andreas Capellanus

Andreas Capellanus, also known as Andrew the Chaplain, and occasionally by a French translation of his name, André le Chapelain, was the 12th-century author of a treatise commonly known as De amore, and often known in English, somewhat misleadingly, as The Art of Courtly Love, though its realistic, somewhat cynical tone suggests that it is in some measure an antidote to courtly love.
