The Iliad 23.417–425

A rift there was in the ground, where the water, swollen by winter rains, had broken away a part of the road and had hollowed all the place. There drave Menelaus in hope that none other might drive abreast of him. But Antilochus turned aside his single-hooved horses, and drave on outside the track, and followed after him, a little at one side. And the son of Atreus was seized with fear, and shouted to Antilochus: Antilochus, thou art driving recklessly; nay, rein in thy horses! Here is the way straitened, but presently it will be wider for passing; lest haply thou work harm to us both by fouling my car.
