80. In another respect the Egyptians are in agreement with some of the Hellenes, namely with the Lacedemonians, but not with the rest, that is to say, the younger of them when they meet the elder give way and move out of the path, and when their elders approach they rise out of their seat. In this which follows however they are not in agreement with any of the Hellenes,—instead of addressing one another in the roads they do reverence, lowering their hand down to their knee. 81. They wear tunics of linen about their legs with fringes, which they call calasiris; above these they have garments of white wool thrown over: woollen garments however are not taken into the temples, nor are they buried with them, for this is not permitted by religion. In these points they are in agreement with the observances called Orphic and Bacchic (which are really Egyptian), 71 and also with those of the Pythagoreans, for one who takes part in these mysteries is also forbidden by religious rule to be buried in woollen garments; and about this there is a sacred story told. 82. Besides these things the Egyptians have found out also to what god each month and each day belongs, and what fortunes a man will meet with who is born on any particular day, and how he will die, and what kind of a man he will be: and these inventions were taken up by those of the Hellenes who occupied themselves about poesy. Portents too have been found out by them more than by all other men besides; for when a portent has happened, they observe and write down the event which comes of it, and if ever afterwards anything resembling this happens, they believe that the event which comes of it will be similar. 83. Their divination is ordered thus:—the art is assigned not to any man, but to certain of the gods, for there are in their land Oracles of Heracles, of Apollo, of Athene, of Artemis, of Ares, and of Zeus, and moreover that which they hold most in honour of all, namely the Oracle of Leto which is in the city of Buto. The manner of divination however is not yet established among them according to the same fashion everywhere, but is different in different places. 84. The art of medicine among them is distributed thus:—each physician is a physician of one disease and of no more; and the whole country is full of physicians, for some profess themselves to be physicians of the eyes, others of the head, others of the teeth, others of the affections of the stomach, and others of the more obscure ailments.
