In Seneca's version of The Trojan Women, the prophet Calchas declares that Astyanax must be thrown from the walls if the Greek fleet is to be allowed favorable winds (365–70), but once led to the tower, the child himself leaps off the walls (1100–3).
The Achaeans may have settled the region while under the leadership of Amphilochus, Calchas, and Mopsus.
In the Roman, the daughter of Calchas is called Briseis, but she is better known under a different name, becoming Criseida in Boccaccio's il Filostrato, Criseyde in Chaucer, Cresseid in Robert Henryson's The Testament of Cresseid and ultimately Cressida in Shakespeare's Troilus and Cressida.
