The species of the elephant is numerous, though they bring forth but one in two or three years. In proportion to the shortness of the life of an animal is its multiplicity of production; and in the elephant the duration of its existence compensates for the smallness of its number; and if it be true that they live 200 years, and propagate until they are 120, each couple may bring forth forty in that time. Besides, having nothing to fear from other animals, and being taken by men with great difficulty and danger, the species has not decreased, and is generally dispersed in all the southern parts of Africa and Asia. They are numerous at Ceylon, in the Mogul dominions, in Bengal, Siam, Pegu, and the other territories of India. They are perhaps, in a greater number in the South of Africa, except some parts which they have abandoned, since they have been so fully inhabited by men. They are faithful to their country, and constant to their climate, for though they can live in temperate regions it does not seem that they ever attempted to settle, or even to travel into them. They were formerly unknown in Europe. It does not seem that Homer, who speaks of the ivory, knew the animal from whom it is obtained. Alexander was the first who rode upon an elephant in Europe. He sent into Greece those which he took at Porus, and were, perhaps, the same which Pyrrhus employed several years after against the Romans, in the Tarentine war, and with which Curius adorned his triumph into Rome. Hannibal afterwards brought them from Africa, made them pass the Alps, and led them almost to the gates of Rome.
