"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 [lotos], 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."
