Res Gestae

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.

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
