When he was about thirteen, a magnificent black horse called Bucephalus, or Bull-head, because it had a white mark like a bull’s face on its forehead, was brought to Philip; but it was so strong and restive that nobody could manage it, and Philip was sending it away, when Alexander begged leave to try to tame it.  First he turned its head to the sun, having perceived that its antics were caused by fear of its own shadow; then stroking and caressing it as he held the reins, he gently dropped his fluttering mantle and leaped on its back, sitting firm through all its leaps and bounds, but using neither whip nor spur nor angry voice, till at last the creature was brought to perfect obedience.  This gentle courage and firmness so delighted Philip that he embraced the boy with tears of joy, and gave him the horse, which, as long as it lived, loved and served him like no one else.  Philip also said that such a boy might be treated as a man, and therefore put him under Aristotle three years earlier than it was usual to begin philosophy; and again he was an apt and loving scholar, learning great wisdom in dealing with men and things, and, in truth, learning everything but how to control his temper.
