Strabo on Alexander and the Brahmans
In India, Alexander the Great (or his representative Onesicritus) had an interview with the Brahman sages, who lived near Taxila. One of these people, a man named Calanus (Indian Kalyana), followed the conqueror to the west, where he died. The story of the interview and the story of the death of Calanus are described in several sources, such as Strabo's Geography 15.1.61, 63-64, which was translated by Horace Leonard Jones.
Alexander and the Brahmans
[15.1.61] Aristobulus says that he saw two of the sophistsnote at Taxila, both Brahmans; and that the elder had head shaved but that the younger had long hair, and that both were followed by disciples; and that when not otherwise engaged they spent their time in the market-place, being honored as counselors and being authorized to take as as gift any merchandise they wished; and that anyone whom they accosted poured over them sesame oil, in such profusion that it flowed down over their eyes; and that since quantities of honey and sesame were put out for sale, they made cakes of it and subsisted free of charge, and that they came up to the table of Alexander, ate dinner standing, and taught him a lesson in endurance by retiring to a place nearby, where the elder fell to the ground on his back and endured the sun's rays and the rains (for it was now raining, since the spring of the year had begun); and that the younger stood on one leg holding aloft in both hands a log about three cubits in length, and when one leg tired he changed the support to the other and kept this up all day long; and that the younger showed a far greater self-mastery than the elder; for although the younger followed the king a short distance, he soon turned back again towards home, and when the king went after him, the man bade him to come himself if he wanted anything of him; but that the elder accompanied the king to the end, and when he was with him changed his dress and mode of life; and that he said, when reproached by some, that he had completed the forty years of discipline which he had promised to observe; and that Alexander gave his children a present.
[15.1.63] [....]
Onesicritus says that he himself was sent to converse with these sophists; for Alexander had heard that the people always went naked and devoted themselves to endurance, and that they were held in very great honor, and that they did not visit other people when invited, but bade them to visit them if they wished to participate in anything they did or said; and that therefore, such being the ease, since to Alexander it did not seem fitting either to visit them or to force them against their will to do anything contrary to their ancestral customs, he himself was sent; and that he found fifteen men at a distance of four kilometers from the city, who were in different postures, standing or sitting or lying naked and motionless till evening, and that they then returned to the city; and that it was very hard to endure the sun, which was so hot that at midday no one else could easily endure walking on the ground with bare feet.
[15.1.64] Onesicritus says that he conversed with one of these sophists, Calanus, who accompanied the kind the king as far as Persis and died in accordance with the ancestral custom, being placed upon a pyre and burned up. He says that Calanus happened to be lying on stones when he first saw him; that he therefore approached him and greeted him; and told him that he had been sent by the king to learn the wisdom of the sophists and report it to him, and that if there was no objection he was ready to hear his teachings; and that when Calanus saw the mantle and broad-brimmed hat and boots he wore, he laughed at him and said: 'In olden times the world was full of barley-meal and wheaten-meal, as now of dust; and fountains then flowed, some with water, others with milk and likewise with honey, and others with wine, and some with olive oil; but, by reason of his gluttony and luxury, man fell into arrogance beyond bounds. But Zeus, hating this state of things, destroyed everything and appointed for man a life of toil. And when self-control and the other virtues in general reappeared, there came again an abundance of blessings. But the condition of man is already close to satiety and arrogance, and there is danger of destruction of everything in existence.'
And Onesicritus adds that Calanus, after saying this, bade him, if he wished to learn, to take off his clothes, to lie down naked on the same stones, and thus to hear his teachings; and that while he was hesitating what to do, Mandanis, who was the oldest and wisest of the sophists, rebuked Calanus as a man of arrogance, and that too after censuring arrogance himself; and that Mandanis called him and said that he commended the king because, although busied with the government of so great an empire, he was desirous of wisdom; for the king was the only philosopher in arms that he ever saw, and that it was the most useful thing in the world if those men were wise who have the power of persuading the willing, and forcing the unwilling, to learn self-control; but that he might be pardoned if, conversing through three interpreters, who, with the exception of language, knew no more than the masses, he should be unable to set forth anything in his philosophy that would be useful; for that, he added, would be like expecting water to flow pure mud!
