Apollo in the shape of dolphin boards the ship and guides the wind
399-403 But Phoebus Apollo
met them: in the open sea he sprang upon their swift ship, like a
dolphin in shape, and lay there, a great and awesome monster, and none
of them gave heed so as to understand; but they sought to cast
the dolphin overboard. But he kept shaking the black ship every way and
make the timbers quiver.
