In all cases, the wool most esteemed is that from the neck of the animal; the best kinds of wool being those of Galatia, Tarentum, Attica, and Miletus. For excoriations, blows, bruises, contusions, crushes, galls, falls, pains in the head and other parts, and for inflammation of the stomach, unwashed wool is applied, with a mixture of vinegar and oil of roses. Reduced to ashes, it is applied to contusions, wounds, and burns, and forms an ingredient in ophthalmic compositions. It is employed, also, for fistulas and suppurations of the ears. For this last purpose, some persons take the wool as it is shorn, while others pluck it from the fleece; they then cut off the ends of it, and after drying and carding it, lay it in pots of unbaked earth, steep it well in honey, and burn it. Others, again, arrange it in layers alternately with chips of torch-pine,[2520] and, after sprinkling it with oil, set fire to it: they then rub the ashes into small vessels with the hands, and let them settle in water there. This operation is repeated and the water changed several times, until at last the ashes are found to be slightly astringent, without the slightest pungency; upon which, they are put by for use, being possessed of certain caustic properties,[2521] and extremely useful as a detergent the eyelids. CHAP. 10.—THIRTY-TWO REMEDIES DERIVED FROM WOOL-GREASE. And not only this, but the filthy excretions even of sheep, the sweat adhering to the wool of the flanks and of the axillary concavities—a substance known as “œsypum”[2522]—are applied to purposes almost innumerable; the grease produced by the sheep of Attica being the most highly esteemed. There are numerous ways of obtaining it, but the most approved method is to take the wool, fresh clipped from those parts of the body, or else the sweat and grease collected from any part of the fleece, and boil it gently in a copper vessel upon a slow fire: this done, it is left to cool, and the fat which floats upon the surface collected into an earthen vessel. The material originally used is then subjected to another boiling, and the two results are washed in cold water; after which, they are strained through a linen cloth and exposed to the sun till they become bleached and quite transparent, and are then put by in a pewter box for keeping.
