誰がシャルル5世 (フランス王)とデートしましたか？

シャルル5世（Charles V, 1338年1月21日 ヴァンセンヌ - 1380年9月16日 ボテ＝シュル＝マルヌ城）は、フランス・ヴァロワ朝第3代の王（在位：1364年 - 1380年）。賢明王（ル・サージュ、le Sage）と呼ばれる。中世末期の行政機構の研究家フランソワーズ・オトランはシャルル5世を税金の父と呼ぶ。最初にドーファン（Dauphin）の称号を有した王太子である。

Biette Cassinel (French pronunciation: [bjɛt də kasinɛl]; c.1320s-1394) was the supposed royal mistress of Charles V of France from 1360 until 1363.

Biette was the daughter of the François Cassinel, sergent d'armes of John II of France, and Alix Deschamps. She was the sister of Ferry Cassinel, bishop of Lodève and Auxerre and eventually archbishop of Rheims.

Biette was married to Gérard de Montagu by 1336. She was the mother of Jean de Montagu, who would rise to become Grand Master of France. It is said by some that Jean was her son by Charles V, while Merlet and Delachenal state there is no evidence for this. Autrand states that a clerk of Parlement skipped two words, concerning Jean's execution, which incorrectly attributed Charles V as Jean's father, instead of his legitimate father Gerard de Montaigu.
