When Jason, the son of the dethroned King of Iolchos, was a little boy, he was sent away from his parents, and placed under the queerest schoolmaster that ever you heard of. This learned person was one of the people, or quadrupeds, called Centaurs. He lived in a cavern, and had the body and legs of a white horse, with the head and shoulders of a man. His name was Chiron; and, in spite of his odd appearance, he was a very excellent teacher, and had several scholars, who afterwards did him credit by making a great figure in the world. The famous Hercules was one, and so was Achilles, and Philoctetes likewise, and Aesculapius, who acquired immense repute as a doctor. The good Chiron taught his pupils how to play upon the harp, and how to cure diseases, and how to use the sword and shield, together with various other branches of education, in which the lads of those days used to be instructed, instead of writing and arithmetic.I have sometimes suspected that Master Chiron was not really very different from other people, but that, being a kind-hearted and merry old fellow, he was in the habit of making believe that he was a horse, and scrambling about the schoolroom on all fours, and letting the little boys ride upon his back. And so, when his scholars had grown up, and grown old, and were trotting their grandchildren on their knees, they told them about the sports of their school days; and these young folks took the idea that their grandfathers had been taught their letters by a Centaur, half man and half horse. Little children, not quite understanding what is said to them, often get such absurd notions into their heads, you know.Be that as it may, it has always been told for a fact (and always will be told, as long as the world lasts), that Chiron, with the head of a schoolmaster, had the body and legs of a horse. Just imagine the grave old gentleman clattering and stamping into the schoolroom on his four hoofs, perhaps treading on some little fellow's toes, flourishing his switch tail instead of a rod, and, now and then, trotting out of doors to eat a mouthful of grass! I wonder what the blacksmith charged him for a set of iron shoes?So Jason dwelt in the cave, with this four-footed Chiron, from the time that he was an infant, only a few months old, until he had grown to the full height of a man. He became a very good harper, I suppose, and skilful in the use of weapons, and tolerably acquainted with herbs and other doctor's stuff, and, above all, an admirable horseman; for, in teaching young people to ride, the good Chiron must have been without a rival among schoolmasters. At length, being now a tall and athletic youth, Jason resolved to seek his fortune in the world, without asking Chiron's advice, or telling him anything about the matter. This was very unwise, to be sure; and I hope none of you, my little hearers, will ever follow Jason's example.But, you are to understand, he had heard how that he himself was a prince royal, and how his father, King Jason, had been deprived of the kingdom of Iolchos by a certain Pelias, who would also have killed Jason, had he not been hidden in the Centaur's cave. And, being come to the strength of a man, Jason determined to set all this business to rights, and to punish the wicked Pelias for wronging his dear father, and to cast him down from the throne, and seat himself there instead.
