and his song;[1816] when their ears are erect, their sense of hearing is very acute, but when dropped, they become deaf.[1817] In other respects the stag is a simple animal, which regards every thing as wonderful, and with a stupid astonishment; so much so, indeed, that if a horse or cow happens to approach it, it will not see the hunter, who may be close at hand, or, if it does see him, it only gazes upon his bow and arrow. Stags cross the sea in herds, swimming in a long line, the head of each resting on the haunches of the one that precedes it, each in its turn falling back to the rear. This has been particularly remarked when they pass over from Cilicia to the island of Cyprus. Though they do not see the land, they still are able to direct themselves by the smell. The males have horns, and are the only animals that shed them every year, at a stated time in the spring; at which period they seek out with the greatest care the most retired places, and after losing them, remain concealed, as though aware that they are unarmed. Still, however, they envy us the good that these might do us; for it is said the right horn, which possesses, as it were, certain medicinal properties, can never be found, a circumstance the more astonishing, from the fact that they change their horns every year, even when kept in parks;[1818] it is generally thought that they bury their horns in the ground. The odour of either horn, when burnt, drives away serpents and detects epilepsy. They also bear the marks of their age on the horns, every year, up to the sixth,[1819] a fresh antler being added; after which period the horns are renewed in the same state, so that by means of them their age cannot be ascertained. Their old age, however, is indicated by their teeth, for then they have only a few, or none at all; and we then no longer perceive, at the base of their horns, antlers projecting from the front of the forehead, as is usually the case with the animal when young. When this animal is castrated it does not shed its horns, nor are they reproduced. When the horns begin to be reproduced, two projections are to be seen, much resembling, at first, dry skin; they grow with tender shoots, having upon them a soft down like that on the head of a reed. So long as they are without horns, they go to feed during the night. As the horns grow, they harden by the heat of the sun, and the animal, from time to time, tries their strength upon the trees; when satisfied with their strength, it leaves its retreat.
