"Both historians, and the more learned of the Indians, among whom the Brahmins may be specified, declare that there is a countless number of these beasts. Among them they enumerate the unicorn, which they call cartazonon, and say that it reaches the size of a horse of mature age, possesses a mane and reddish yellow hair, and that it excels in swiftness through the excellence of its feet and of its whole body. Like the elephant, it has inarticulate feet, and it has a boar's tail; one black horn projects between the eyebrows, not awkwardly, but with a certain natural twist, and terminating in a sharp point. "It has, of all animals, the harshest and most contentious voice. It is said to be gentle to other beasts approaching it, but to fight with its fellows. Not only are the males at variance in natural contention amongst themselves, but they also fight with the females, and carry their combats to the length of killing the conquered; for not only are their bodies generally indued with great strength, but also they are armed with an invincible horn. It frequents desert regions and wanders alone and solitary. In the breeding season it is of gentle demeanour towards the female, and they feed together; when this has passed and the female has become gravid, it again becomes fierce and wanders alone. "They say that the young, while still of tender age, are carried to the King of the Prasians for exhibition of their strength, and exposed in combats on festivals; for no one remembers them to have been captured of mature age." Cæsar[288] records the reputed existence in his day, within the bounds of the great Hercynian Forest, of a bull, shaped like a stag, with one horn projecting from the middle of its forehead and between the ears. Cosmas,[289] surnamed Indicopleustes, a merchant of Alexandria, who lived in the sixth century, and made a voyage to India, and subsequently wrote works on cosmography, gives a figure of the unicorn, not, as he says, from actual sight of it, but reproduced from four figures of it in brass contained in the palace of the King of Ethiopia. He states, from report, that "it is impossible to take this ferocious beast alive; and that all its strength lies in its horn. When it finds itself pursued and in danger of capture, it throws itself from a precipice, and turns so aptly in falling, that it receives all the shock upon the horn, and so escapes safe and sound." It is noteworthy that this mode of escape is attributed, at the present day, to both the musk ox and the Ovis Ammon. Marco Polo may or may not indicate a rhinoceros in the passage, "Après avoir descendu ces deux journées et demie, on trouve une province au midi qui est sur les confins de l'Inde, on l'appelle Amien--on marche quinze journées par des lieux desertes et par de grands bois où il y a beaucoup d'éléphants et de licornes et d'autres bêtes sauvages. Il n'y a ni hommes ni habitations aussi, nous laisserons ce lieu."
