In vain you expect much information, _de Re Accipitraria_, of Falconry, Hawks or Hawking, from very ancient Greek or Latin Authours; that Art being either unknown or so little advanced among them, that it seems to have proceeded no higher than the daring of Birds: which makes so little thereof to be found in _Aristotle_, who onely mentions some rude practice thereof in _Thracia_; as also in _Ælian_, who speaks something of Hawks and Crows among the Indians; little or nothing of true Falconry being mention'd before _Julius Firmicus_, in the days of _Constantius_, Son to _Constantine_ the Great. Yet if you consult the accounts of later Antiquity left by _Demetrius_ the Greek, by _Symmachus_ and _Theodosius_, and by _Albertus Magnus_, about five hundred years ago, you, who have been so long acquainted with this noble Recreation, may better compare the ancient and modern practice, and rightly observe how many things in that Art are added, varied, disused or retained in the practice of these days. In the Diet of Hawks, they allowed of divers Meats which we should hardly commend. For beside the Flesh of Beef, they admitted of Goat, Hog, Deer, Whelp and Bear. And how you will approve the quantity and measure thereof, I make some doubt; while by weight they allowed half a pound of Beef, seven ounces of Swines Flesh, five of Hare, eight ounces of Whelp, as much of Deer, and ten ounces of He-Goats Flesh. In the time of _Demetrius_ they were not without the practice of Phlebotomy or Bleeding, which they used in the Thigh and Pounces; they plucked away the Feathers on the Thigh, and rubbed the part, but if the Vein appeared not in that part, they opened the Vein of the fore Talon. In the days of _Albertus_, they made use of Cauteries in divers places: to advantage their sight they seared them under the inward angle of the eye; above the eye in distillations and diseases of the Head; in upward pains they seared above the Joint of the Wing, and at the bottom of the Foot, against the Gout; and the chief time for these cauteries they made to be the month of _March_. In great coldness of Hawks they made use of Fomentations, some of the steam or vapour of artificial and natural Baths, some wrapt them up in hot Blankets, giving them Nettle Seeds and Butter. No Clysters are mention'd, nor can they be so profitably used; but they made use of many purging Medicines. They purged with Aloe, which, unto larger Hawks, they gave in the bigness of a Great Bean; unto less, in the quantity of a _Cicer_, which notwithstanding I should rather give washed, and with a few drops of Oil of Almonds: for the Guts of flying Fowls are tender and easily scratched by it; and upon the use of Aloe both in Hawks and Cormorants I have sometimes observed bloody excretions. In phlegmatick causes they seldom omitted _Stave-saker_, but they purged sometimes with a Mouse, and the Food of boiled Chickens, sometimes with good Oil and Honey.
