(3 syl.). The patronymic name of Hippodamia, daughter of Briseus (2 syl.). A concubine of Achilles, to whom he was greatly attached. When Agamemnon was compelled to give up his own concubine, who was the daughter of a priest of Apollo, he took Briseis away from Achilles. This so annoyed the hero that he refused any longer to go to battle, and the Greeks lost ground daily. Ultimately, Achilles sent his friend Patroclos to supply his place. Patroclos was slain, and Achilles, towering with rage, rushed to battle, slew Hector, and Troy fell.
