When Alexander was about twelve years old, a horse was brought for sale from Thessaly called Bucephalus. The price required was about £2,500 sterling, or $12,000. Yet when any one attempted to mount him, he became restive and unmanageable. Philip was incensed that such a price should be asked for so vicious a beast, but Alexander had observed him carefully, and saw that he was indeed a noble creature. He therefore wished to try him. His father rebuked him sharply, but the prince persevered, and desired to mount the horse. “If you are not able to ride him upon trial,” said Philip, “what forfeit will you pay?” “The price of the horse,” said Alexander. This produced a laugh rather at Alexander’s expense—but the forfeit was agreed upon, and he ran to the horse. He had observed that he was startled at his shadow, the sun shining very brightly; so he turned his head to the sun, leaped lightly upon his back, obtained a firm seat, and gave the animal the rein. The noble beast felt, with that quick intelligence of which his race is capable, that one worthy to be his master was on his back, and set forward. Finding him inclined to run, Alexander, nothing daunted, but with a spirit as wild and fearless as his own, and no doubt with a bounding and joyous sympathy, gave him the spur, and made him fly over the plain. Philip and all his courtiers around him were greatly frightened at first, but soon Alexander wheeled Bucephalus about, and rode him back to the place from which he started. The animal was completely subdued; yet there was something in his proud look, as he now stood still before the admiring throng, which seemed to say, “I yielded, but only to one worthy of being a conqueror.” Alexander was received by a shout of acclamation—but Philip was overcome by the noble chivalry of his boy, and wept in very joy. “Seek another kingdom, my son!” said he, in the fulness of his heart, “for Macedon is too small for thee!” Such was the value in those days set upon personal gallantry and courage; and we know that these qualities are of the utmost importance, when hard blows usually decide the fate of empires.
