History of Herodotus

Excerpt from Herodotus:

In the neighbourhood of Thebes there are some sacred serpents which are perfectly harmless. They are of small size, and have two horns growing out of the top of the head. These snakes, when they die, are buried in the temple of Jupiter, the god to whom they are sacred.

I went once to a certain place in Arabia, almost exactly opposite the city of Buto, to make inquiries concerning the winged serpents. On my arrival I saw the back-bones and ribs of serpents in such numbers as it is impossible to describe: of the ribs there were a multitude of heaps, some great, some small, some middle-sized. The place where the bones lie is at the entrance of a narrow gorge between steep mountains, which there open upon a spacious plain communicating with the great plain of Egypt. The story goes that with the spring the winged snakes come flying from Arabia towards Egypt, but are met in this gorge by the birds called ibises, who forbid their entrance and destroy them all. The Arabians assert, and the Egyptians also admit, that it is on account of the service thus rendered that the Egyptians hold the ibis in so much reverence.

The ibis is a bird of a deep-black colour, with legs like a crane; its beak is strongly hooked, and its size is about that of the land-rail. This is a description of the black ibis which contends with the serpents. The commoner sort, for there are two quite distinct species, has the head and the whole throat bare of feathers; its general plumage is white, but the head and neck are jet black, as also are the tips of the wings and the extremity of the tail; in its beak and legs it resembles the other species. The winged serpent is shaped like the water-snake. Its wings are not feathered, but resemble very closely those of the bat. And thus I conclude the subject of the sacred animals.
