The Egyptians are averse to adopt Greek customs, or, in a word, those of any other nation. This feeling is almost universal among them. At Chemmis, however, which is a large city in the Thebaic canton, near Neapolis, there is a square enclosure sacred to Perseus, son of Danae. Palm trees grow all round the place, which has a stone gateway of an unusual size, surmounted by two colossal statues, also in stone. Inside this precinct is a temple, and in the temple an image of Perseus. The people of Chemmis say that Perseus often appears to them, sometimes within the sacred enclosure, sometimes in the open country: one of the sandals which he has worn is frequently found- two cubits in length, as they affirm- and then all Egypt flourishes greatly. In the worship of Perseus Greek ceremonies are used; gymnastic games are celebrated in his honour, comprising every kind of contest, with prizes of cattle, cloaks, and skins. Imade inquiries of the Chemmites why it was that Perseus appeared to them and not elsewhere in Egypt, and how they came to celebrate gymnastic contests unlike the rest of the Egyptians: to which they answered, "that Perseus belonged to their city by descent. Danans and Lynceus were Chemmites before they set sail for Greece, and from them Perseus was descended," they said, tracing the genealogy; "and he, when he came to Egypt for the purpose" (which the Greeks also assign) "of bringing away from Libya the Gorgon's head, paid them a visit, and acknowledged them for his kinsmen- he had heard the name of their city from his mother before he left Greece- he bade them institute a gymnastic contest in his honour, and that was the reason why they observed the practice."The customs hitherto described are those of the Egyptians who live above the marsh-country. The inhabitants of the marshes have the same customs as the rest, as well in those matters which have been mentioned above as in respect of marriage, each Egyptian taking to himself, like the Greeks, a single wife; but for greater cheapness of living the marsh-men practise certain peculiar customs, such as these following. They gather the blossoms of a certain water-lily, which grows in great abundance all over the flat country at the time when the Nile rises and floods the regions along its banks- the Egyptians call it lotus- they gather, I say, the blossoms of this plant and dry them in the sun, after which they extract from the centre of each blossom a substance like the head of a poppy, which they crush and make into bread. The root of the lotus is likewise eatable, and has a pleasant sweet taste: it is round, and about the size of an apple. There is also another species of the lily in Egypt, which grows, like the lotus, in the river, and resembles the rose. The fruit springs up side by side with the blossom, on a separate stalk, and has almost exactly the look of the comb made by wasps. It contains a number of seeds, about the size of an olive-stone, which are good to eat: and these are eaten both green and dried. The byblus (papyrus), which grows year after year in the marshes, they pull up, and, cutting the plant in two, reserve the upper portion for other purposes, but take the lower, which is about a cubit long, and either eat it or else sell it. Such as wish to enjoy the byblus in full perfection bake it first in a closed vessel, heated to a glow. Some of these folk, however, live entirely on fish, which are gutted as soon as caught, and then hung up in the sun: when dry, they are used as food.
Gregarious fish are not found in any numbers in the rivers; they frequent the lagunes, whence, at the season of breeding, they proceed in shoals towards the sea. The males lead the way, and drop their milt as they go, while the females, following close behind, eagerly swallow it down. From this they conceive, and when, after passing some time in the sea, they begin to be in spawn, the whole shoal sets off on its return to its ancient haunts. Now, however, it is no longer the males, but the females, who take the lead: they swim in front in a body, and do exactly as the males did before, dropping, little by little, their grains of spawn as they go, while the males in the rear devour the grains, each one of which is a fish. A portion of the spawn escapes and is not swallowed by the males, and hence come the fishes which grow afterwards to maturity.
Whan any of this sort of fish are taken on their passage to the sea, they are found to have the left side of the head scarred and bruised; while if taken on their return, the marks appear on the right. The reason is that as they swim down the Nile seaward, they keep close to the bank of the river upon their left, and returning again up stream they still cling to the same side, hugging it and brushing against it constantly, to be sure that they miss not their road through the great force of the current. When the Nile begins to rise, the hollows in the land and the marshy spots near the river are flooded before any other places by the percolation of the water through the riverbanks; and these, almost as soon as they become pools, are found to be full of numbers of little fishes. I think that I understand how it is this comes to pass. On the subsidence of the Nile the year before, though the fish retired with the retreating waters, they had first deposited their spawn in the mud upon the banks; and so, when at the usual season the water returns, small fry are rapidly engendered out of the spawn of the preceding year. So much concerning the fish.
