Cressida

In mediaeval accounts of the Trojan War, the daughter of Calchas, a Trojan priest; probably the story was a misunderstanding of Calchas and Chryseis in the Iliad. Beloved by Troilus, a Trojan prince, she deserted him for Diomedes when transferred to the Greek camp.

Cressida is a character who appears in many Medieval and Renaissance retellings of the story of the Trojan War. She is a Trojan woman who falls in love with one of the sons of King Priam, Troilus. Chaucer's poem, however, portrayed a far more sympathetic Criseyde showing a self-conscious awareness of her literary status: "Alas, of me until the world's end shall be wrote no good song".

The story of Troilus and Cressida is a medieval invention and does not appear in any Greek legends. In the Doctor Who storyline Myth Makers (with William Hartnell as the Doctor), the TARDIS is captured by the Trojans with Vicki (Maureen O'Brien) still inside. Forced to emerge from the TARDIS, Vicki meets Priam, King of Troy. Later, Vicki/Cressida meets and becomes enamored with Priam's youngest son Troilus. After Troy falls (with the unwilling, but necessary help of the Doctor), Vicki stays behind to rebuild Troy with Troilus.
