As for wine, those who serve the god in Heliopolis bring none at all into the shrine, since they feel that it is not seemly to drink in the day-time while their Lord and King is looking upon them. The others use wine, but in great moderation. They have many periods of holy living when wine is prohibited, and in these they spend their time exclusively in studying, learning, and teaching religious matters. Their kings also were wont to drink a limited quantity prescribed by the sacred writings, as Hecataeus has recorded; and the kings are priests. The beginning of their drinking dates from the reign of Psammetichus; before that they did not drink wine nor use it in libation as something dear to the gods, thinking it to be the blood of those who had once battled against the gods, and from whom, when they had fallen and had become commingled with the earth, they believed vines to have sprung. This is the reason why drunkenness drives men out of their senses and crazes them, inasmuch as they are then filled with the blood of their forbears. These tales Eudoxus says in the second book of his World Travels are thus related by the priests. As for sea-fish, all Egyptians do not abstain from all of them, but from some kinds only; as, for example, the inhabitants of Oxyrhynchus abstain from those that are caught with a hook; for, inasmuch as they revere the fish called oxyrhynchus (the pike), they are afraid that the hook may be unclean, since an oxyrhynchus may have been caught with it. The people of Syenê abstain from the phagrus (the sea-bream); for this fish is reputed to appear with the oncoming of the Nile, and to be a self-sent messenger, which, when it is seen, declares to a glad people the rise of the river. The priests, however, abstain from all fish; and on the ninth day of the first month, when every one of the other Egyptians eats a broiled fish in front of the outer door of his house, the priests do not even taste the fish, but burn them up in front of their doors. For this practice they have two reasons, one of which is religious and curious, and I shall discuss it at another time, since it harmonizes with the sacred studies touching Osiris and Typhon; the other is obvious and commonplace, in that it declares that fish is an unnecessary and superfluous food, and confirms the words of Homer, who, in his poetry, represents neither the Phaeacians, who lived amid a refined luxury, nor the Ithacans, who dwelt on an island, as making any use of fish, nor did even the companions of Odysseus, while on such a long voyage and in the midst of the sea, until they had come to the extremity of want. In fine, these people hold the sea to be derived from purulent matter, and to lie outside the confines of the world and not to be a part of it or an element, but a corrupt and pestilential residuum of a foreign nature.
