32. We shall observe this difference more evidently, if we direct our discourses upon the most ancient and greatest works of common society, which are the works of generation and procreation of offspring. For in the first place, those fish that frequent the shores next adjoining to vast lakes or great rivers, when they are near their time of bringing forth, retire up into those places, seeking the fresh waters which are more gentle and void of brine. For tranquillity is most convenient for such as bring forth, and there is most safety in rivers and lakes for their young ones, as being freest from the devouring monsters of the sea. Which is the reason that there is the greatest plenty of fish about the Euxine Sea, where there are no whales, but only small sea-calves or little dolphins. Besides, the mixture of rivers, many in number, and those very large, that fall into the Pontus, make the temperature more kindly and proper for breeding and bringing forth. And that is most wonderful which is reported of the anthias, which Homer[92] calls the sacred fish, though some interpret sacred to signify great in that place, as we call a certain great bone _os sacrum_, and the epilepsy, being a great disease, the _sacred disease_, though others interpret that to be sacred which ought not to be touched, as being dedicated to holy use. And Eratosthenes seems to take the gilthead, so called from the golden hair about his eyes, for the sacred fish; though many believe it to be the ellops,—a fish seldom seen and difficult to be caught, yet many times it appears in the rivers of Pamphylia. So they that catch them are crowned, and their boats are also adorned with garlands, and as they pass along they are received and honored with loud shouts and clapping of hands. However it be, most people take the anthias to be a sacred fish, because that where the anthias appears, there are no sea-monsters, but the sponge-cutters dive boldly, and the fish as fearlessly spawn, as having a pledge for their security. And the reason is twofold, either because the sea-monsters dread the anthias, as elephants dread a hog, and lions a cock; or else it is a sign that there are no sea-monsters in those places, which the anthias knows and observes, as being an intelligent fish, endued with sense and a good memory. 33. Then again, the care of their young is common to both sexes. For the males never devour their offspring, but remain and abide constantly by the spawn, protecting it with a diligent watchfulness, as Aristotle relates; and those that accompany the females moisten the spawn with a small quantity of milky seed; for that otherwise the spawn will not grow, but remains imperfect and never arrives at the due proportion. Particularly the fish called phycides make themselves nests in the seaweed to preserve their spawn from the waves.
