One of the daughters of Ogyges, who as well as her two sisters, Thelxionoea and Aulis, were regarded as supernatural beings, who watched over oaths and saw that they were not taken rashly or thoughtlessly. Their name was Praxidikai, and they had a temple in common at the foot of the Telphusian mount in Boeotia. The representations of these divinities consisted of mere heads, and no parts of animals were sacrificed to them, except heads. (Paus. ix. 33. § 2, 4; Panyasis, ap. Steph. Byz. s. v. Tremilê; Suid. s. v. Praxidikê.)
