Later on Menelaus joined us at Lesbos, and found us making up our minds about our course--for we did not know whether to go outside Chios by the island of Psyra, keeping this to our left, or inside Chios, over against the stormy headland of Mimas.
And the Centaurs were gathered against them on the other side with Petraeus and Asbolus the diviner, Arctus, and Ureus, and black-haired Mimas, and the two sons of silver, and they had pinetrees of gold in their hands, and they were rushing together as though they were alive and striking at one another hand to hand with spears and with pines.
