The English, who backed Peter, also remembered the king positively. Geoffrey Chaucer visited Castile during Peter's reign and lamented the monarch's death in The Monk's Tale, part of The Canterbury Tales. (Chaucer's patron, John of Gaunt, 1st Duke of Lancaster, had fought on Peter's side in his struggle to reclaim the throne.) The English Lake Poet Robert Southey was presented in 1818 with a copy of a five-act play by the Novelist Ann Doherty, entitled Peter the Cruel, King of Castile and Leon.
