Q: Context: Andreas Capellanus ( Capellanus meaning `` chaplain '' ) , 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 ( `` About Love '' ) , 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 . Little is known of Andreas Capellanus 's life , but he is presumed to have been a courtier of Marie de Champagne , and probably of French origin ., Chivalry, or the chivalric code, is a code of conduct associated with the medieval institution of knighthood which developed between 1170 and 1220. The ideals of chivalry were popularized in medieval literature, especially the Matter of Britain and Matter of France, the former based on Geoffrey of Monmouth's "Historia Regum Britanniae" which introduced the legend of King Arthur, written in the 1130s., Courtly love (or fin'amor in Occitan) was a medieval European literary conception of love that emphasized nobility and chivalry. Medieval literature is filled with examples of knights setting out on adventures and performing various services for ladies because of their "courtly love". This kind of love is originally a literary fiction created for the entertainment of the nobility, but as time passed, these ideas about love changed and attracted a larger audience. In the high Middle Ages, a "game of love" developed around these ideas as a set of social practices. "Loving nobly" was considered to be an enriching and improving practice., Subject: andreas capellanus, Relation: date_of_death, Options: (A) 1170 (B) 1220
