PETRO². Pedro, king of Cyprus (fl. fourteenth century), was known as Pierre de Lusignan. Like Don Pedro of Castile, he had a reputation for cruelty, and it was said that his cruelty to Marie de Giblet led to his assassination in 1369. Haldeen Braddy suggests that, although Chaucer may have heard the story from his acquaintances, Machaut's poem, La Prise d'Alexandrie (1369), may have provided additional information, since Machaut presents Pierre de Lusignan in a favorable light. Pierre made a great impression on Machaut when he visited Paris for Charles V's coronation. He also visited London and Paris in 1363 and 1364 to solicit aid for his crusade to the Holy Land. He conquered Alexandria in 1365 (Froissart I: 217-223).

The Monk tells a brief story of Petro, MkT 2391-2398.

The name appears medially, MkT 2391.
