Res Gestae

However, too great a rise of the Nile is as harmful to the crops as too small a one is unfruitful. For if it soaks the land for too long a time with an excess of water, it delays the cultivation of the fields; but if the rise is too small, it threatens a bad harvest. No landowner has ever wished for a higher rise than sixteen cubits. But if there is a more moderate rise, seeds sown on a

Egypt abounds also in many animals, some of which are terrestrial, some aquatic; and there are others which live both on land and in the water, and hence are called amphibious. And on the dry plains roebucks feed and antelopes and spinturnicia,[*](A kind of monkey.) laughable for their utter ugliness, and other monsters, which it is not worth while to enumerate.

Now among aquatic animals crocodiles abound everywhere in that region, a destructive four-footed monster, a curse to the land, accustomed to both elements. It has no tongue, and moves only its upper jaw; its teeth are arranged like those of a comb, and whatever it meets it persistently attacks with destructive bites. It produces its young from eggs resembling those of geese.

And, if besides the claws with which it is armed it also had thumbs, its strength would be great enough to overturn even ships; for it sometimes attains a length of eighteen cubits. At night it remains quiet in the water; in the daytime it suns itself on land, trusting to its hide, which is so strong that its mail-clad back can hardly be pierced by the bolts of artillery.

Now, savage as these same beasts always are, during the seven festal days on which the priests at Memphis celebrate the birthday of the Nile, as if by a kind of military truce they lay aside all their

Besides those that lose their lives through accident, some are destroyed by creatures resembling dolphins, which are found in that same river and with sawlike dorsal fins tear the crocodiles’ soft bellies; and others die in the following manner.

The trochilus, a little bird, as it looks for bits of food, flutters and plays about the crocodile as it lies outstretched, and pleasantly tickling its cheeks, makes its way as far as its throat. Seeing this going on, a water rat, a kind of ichneumon, enters the opening of the crocodile’s mouth, to which the bird has shown the way, and after lacerating its belly and tearing its vitals to pieces, forces its way out.[*](As a matter of fact, the ichneumon destroys only the eggs of the crocodile; cf. Diod. Sic. i. 35, 7; Solinus, 32, 25, agrees with Ammianus, and in 32, 26, tells of the destruction of crocodiles by dolphins with sharp dorsal fins.)

Yet daring as this monster is towards those who run from it, when it sees that it has a daring opponent it is most timorous. It has sharper sight when on land, and during the four winter months it is said to take no food.

Hippopotami also, or river-horses,[*](Cf. Hdt. ii. 71; Diod. Sic. i. 35, 8; Pliny, N.H. viii. 95.) are produced in those parts, animals sagacious beyond all unreasoning beasts, with cloven hooves like horses and short tails. Of their cunning it will suffice for the present to give two instances.

This monster makes its lair amid a thick growth of high and rough reeds and with watchful care looks about for a time of quiet; when free means are offered, it goes forth to feed upon the cornfields. And when it has finally begun to return, gorged with

Also, when by excessive greed it has made its belly bulge and grown sluggish, it rolls its thighs and legs on freshly cut reeds, in order that the blood flowing from its wounded feet may relieve its repletion; and it keeps the injured parts covered with mud until the raw places scab over.
