Philip admired the horse greatly, and bade the grooms try him, to see if his gait was good. One after another mounted, only to be thrown a few minutes later by the fiery, restless steed, which was becoming very much excited. The horse seemed so skittish that Philip finally told the men to lead him away, adding that a man would be foolish to purchase such a useless animal. Alexander then stepped forward and begged permission to try him. His father first made fun of him for asking to mount a horse which none of the grooms could manage; but, as Alexander persisted in his wish, he was finally allowed to make the attempt. The young prince then quietly walked up to the excited horse, took the bridle, held it firmly, and began to speak gently and pat the steed's arched neck. After a moment, Alexander led Bucephalus forward a few steps, and then turned him around, for he had noticed that the horse was frightened by his shadow. Then, when the shadow lay where he could not see it, and where it could no longer frighten him, the young man dropped his cloak quietly, and vaulted upon the horse's back. Once more Bucephalus reared, pranced, kicked, and ran; but Alexander sat firmly on his back, spoke to him gently, and, making no effort to hold him in, let him speed across the plain. [Illustration: Alexander and Bucephalus.] In a few moments the horse's wildness was over, and Alexander could ride back to his proud father, sitting upon a steed which obeyed his slightest touch. Philip was so delighted with the coolness, courage, and good horsemanship that Alexander had shown on this occasion, that he made him a present of the steed. Bucephalus became Alexander's favorite mount, and, while he would allow no one else to ride him, he obeyed his master perfectly. Although most young men began the study of philosophy only at sixteen, Alexander was placed under the tuition of Ar'is-totle soon after his first ride on Bucephalus. This philosopher was a pupil of Plato. He was so learned and well known, that Philip, in writing to him to tell him of Alexander's birth, expressed his pleasure that the gods had allowed his son to live in the same age with so great a teacher. Alexander loved Aristotle dearly, and willingly learned all that was required of him. He often said that he was very grateful, for this philosopher had taught him all the good he knew. Alexander's remarkable coolness, judgment, and perseverance were largely owing to his teacher, and, had he always followed Aristotle's advice, he would have been truly great. But although Alexander did not always practice the virtues which Aristotle had tried to teach him, he never forgot his old tutor. He gave him large sums of money, so that the philosopher could continue his studies, and find out new things; and during his journeys he always sent him complete collections of the animals and plants of the regions he visited.
