The Sportsman: On Hunting, a Sportsman's Manual, Commonly Called Cynegeticus

To the gods themselves is due the discovery, to Apollo and Artemis, patrons of the chase and protectors of the hound. As a guerdon they bestowed it upon Cheiron, by reason of his uprightness, and he took it and was glad, and turned the gift to good account. At his feet sat many a disciple, to whom he taught the mystery of hunting and of chivalry—to wit, Cephalus, Asclepius, Melanion, Nestor, Amphiaraus, Peleus, Telamon, Meleager, Theseus and Hippolytus, Palamedes, Odysseus, Menestheus, Diomed, Castor and Polydeuces, Machaon and Podaleirius, Antilochus, Aeneas and Achilles: of whom each in his turn was honoured by the gods. And let none marvel that of these the greater part, albeit well-pleasing to the gods, nevertheless were subject to death—which is the way of nature, but their fame has grown—nor yet that their prime of manhood so far differed. The lifetime of Cheiron sufficed for all his scholars; the fact being that Zeus and Cheiron were brethren, sons of the same father but of different mothers—Zeus of Rhea, and Cheiron of the nymph Nais; and so it is that, though older than all of them, he died not before he had taught the youngest—to wit, the boy Achilles.
