Cressida f
English: from a medieval legend, told by Chaucer and Shakespeare among others, set in ancient Troy. Cressida is a Trojan princess, daughter of Calchas, a priest who has defected to the Greeks. When she is restored to her father, she jilts her Trojan lover Troilus in favour of the Greek Diomedes. The story is not found in classical sources. Chaucer used the name in the form Criseyde, getting it from Boccaccio's Criseida. This in turn is ultimately based on Greek Khryseis (a derivative of khrysos gold), the name of a Trojan girl who is mentioned briefly as a prisoner of the Greeks at the beginning of Homer's Iliad. Chaucer's version of the name was Latinized by Shakespeare as Cressida. In spite of the unhappy associations of the story, the name has enjoyed some popularity in the 20th century.
