This Inachus did, says Io. And yet Inachus acted as if he were ignorant of what had happened to his daughter. For he sent Cyrnus 1 to look for her, and this man came as far as Caria, the southwestern region of Asia Minor, and not finding her, settled there. Also Lyrcus 2 is said to have been sent by Io's father to search for her, and after having covered a great deal of land and sea without finding the girl, he finally renounced the quest; but being too afraid of Inachus to return to Argos, he went instead to King Caunus of Caria, where he married the king's daughter.
