The "Livre du Roy Modus" gives the most minute and curious details on the noble science of hawking. For instance, it tells us that the _nobility_ of the falcon was held in such respect that their utensils, trappings, or feeding-dishes were never used for other birds. The glove on which they were accustomed to alight was frequently elaborately embroidered in gold, and was never used except for birds of their own species. In the private establishments the leather hoods, which were put on their heads to prevent them seeing, were embroidered with gold and pearls and surmounted with the feathers of birds of paradise. Each bird wore on his legs two little bells with his owner's crest upon them; the noise made by these was very distinct, and could be heard even when the bird was too high in the air to be seen, for they were not made to sound in unison; they generally came from Italy, Milan especially being celebrated for their manufacture. Straps were also fastened to the falcon's legs, by means of which he was attached to the perch; at the end of this strap was a brass or gold ring with the owner's name engraved upon it. In the royal establishments each ring bore on one side, "I belong to the king," and on the other the name of the Grand Falconer. This was a necessary precaution, for the birds frequently strayed, and, if captured, they could thus be recognised and returned. The ownership of a falcon was considered sacred, and, by an ancient barbaric law, the stealer of a falcon was condemned to a very curious punishment. The unfortunate thief was obliged to allow the falcon to eat six ounces of the flesh of his breast, unless he could pay a heavy fine to the owner and another to the king.

If he was a freeman, the nobles outbid each other as to who should secure his services; if he was a serf, his master kept him as a rare treasure, only parted with him as a most magnificent present, or sold him for a considerable sum. Like the clever huntsman, a good falconer (Fig. 156) was bound to be a man of varied information on natural history, the veterinary art, and the chase; but the profession generally ran in families, and the son added his own experience to the lessons of his father. There were also special schools of venery and falconry, the most renowned being of course in the royal household.
