Their ignorance is proved by the silence even of those who professedly treat of the arts of hunting and the history of animals. Aristotle, (Hist. Animal. l. ix. c. 36, tom. i. p. 586, and the Notes of his last editor, M. Camus, tom. ii. p. 314,) Pliny, (Hist. Natur. l. x. c. 10,) Aelian (de Natur. Animal. l. ii. c. 42,) and perhaps Homer, (Odyss. xxii. 302 - 306,) describe with astonishment a tacit league and common chase between the hawks and the Thracian fowlers.
