6. When he departed, having fully accomplished the sacrifices, letters were brought to him from the governor of Egypt, who informed him that after a long time he had succeeded in finding a bull Apis, which he had been seeking with great labour, a circumstance which, in the opinion of the inhabitants of those regions, indicates prosperity, abundant crops, and several other kinds of good fortune. 7. On this subject it seems desirable to say a few words. Among the animals which have been consecrated by the reverence of the ancients, Mnevis and Apis are the most eminent. Mnevis, concerning whom there is nothing remarkable related, is consecrated to the sun, Apis to the moon. But the bull Apis is distinguished by several natural marks; and especially by a crescent-shaped figure, like that of a new moon, on his right side. After living his appointed time, he is drowned in the sacred fountain (for he is not allowed to live beyond the time fixed by the sacred authority of their mystical books; nor is a cow brought to him more than once a year, who also must be distinguished with particular marks); then another is sought amid great public mourning; and if one can be found distinguished by all the required marks, he is led to Memphis, a city of great renown, and especially celebrated for the patronage of the god Æsculapius. 8. And after he has been led into the city by one hundred priests, and conducted into a chamber, he is looked upon as consecrated, and is said to point out by evident means the signs of future events. Some also of those who come to him he repels by unfavourable signs; as it is reported he formally rejected Cæsar Germanicus when he offered him food; thus portending what shortly happened. XV. § 1. Let us then, since the occasion seems to require it, touch briefly on the affairs of Egypt, of which we have already made some mention in our account of the emperors Hadrian and Severus, where we related several things which we had seen.[133] 2. The Egyptian is the most ancient of all nations, except indeed that its superior antiquity is contested by the Scythians: their country is bounded on the south[134] by the greater Syrtes, Cape Ras, and Cape Borion, the Garamantes, and other nations; on the east, by Elephantine, and Meroe, cities of the Ethiopians, the Catadupi, the Red Sea, and the Scenite Arabs, whom we now call Saracens. On the north it joins a vast track of land, where Asia and the Syrian provinces begin; on the west it is bounded by the Sea of Issus, which some call the Parthenian Sea. 3. We will also say a few words concerning that most useful of all rivers, the Nile, which Homer calls the Ægyptus; and after that we will enumerate other things worthy of admiration in these regions.
