There is also another sacred bird called the phoenix which I did not myself see except in painting, for in truth he comes to them very rarely, at intervals, as the people of Heliopolis say, of five hundred years; and these say that he comes regularly when his father dies; and if he be like the painting he is of this size and nature, that is to say, some of his feathers are of gold colour and others red, and in outline and size he is as nearly as possible like an eagle. This bird they say (but I cannot believe the story) contrives as follows:—setting forth from Arabia he conveys his father, they say, to the temple of the Sun (Helios) plastered up in myrrh, and buries him in the temple of the Sun; and he conveys him thus:—he forms first an egg of myrrh as large as he is able to carry, and then he makes trial of carrying it, and when he has made trial sufficiently, then he hollows out the egg and places his father within it and plasters over with other myrrh that part of the egg where he hollowed it out to put his father in, and when his father is laid in it, it proves (they say) to be of the same weight as it was; and after he has plastered it up, he conveys the whole to Egypt to the temple of the Sun. Thus they say that this bird does. There are also about Thebes sacred serpents, not at all harmful to men, which are small in size and have two horns growing from the top of the head: these they bury when they die in the temple of Zeus, for to this god they say that they are sacred. There is a region moreover in Arabia, situated nearly over against the city of Buto, to which place I came to inquire about the winged serpents: and when I came thither I saw bones of serpents and spines in quantity so great that it is impossible to make report of the number, and there were heaps of spines, some heaps large and others less large and others smaller still than these, and these heaps were many in number. This region in which the spines are scattered upon the ground is of the nature of an entrance from a narrow mountain pass to a great plain, which plain adjoins the plain in Egypt; and the story goes that at the beginning of spring winged serpents from Arabia fly towards Egypt, and the birds called ibises meet them at the entrance to this country and do not suffer the serpents to go by but kill them. On account of this deed it is (say the Arabians) that the ibis has come to be greatly honoured by the Egyptians, and the Egyptians also agree that it is for this reason that they honour these birds. The outward form of the ibis is this:—it is a deep black all over, and has legs like those of a crane and a very curved beak, and in size it is about equal to a rail: this is the appearance of the black kind which fight with the serpents, but of those which most crowd round men's feet (for there are two several kinds of ibises) the head is bare and also the whole of the throat, and it is white in feathering except the head and neck and the extremities of the wings and the rump (in all these parts of which I have spoken it is a deep black), while in legs and in the form of the head it resembles the other. As for the serpent its form is like that of the watersnake; and it has wings not feathered but most nearly resembling the wings of the bat. Let so much suffice as has been said now concerning sacred animals.
