THIBA(Θίβα: Eth. Θίβιος), a district in Pontus, so called from an Amazon slain there by Hercules. The inhabitants were said to be socerers, whose breath was poisonous, and who would not perish if thrown into the water, but would float on the surface. (Eustath. ad Dionys. Per. 828; Steph. B. s. v. Θιβαΐς;Pint. Symp. 5.7.1; Phylarch. ap. Plin. 7.2. s. 2.)
