Greek Texts & Translations

Serum is of two kinds: one is the mild whey of the blood; the other, being derived from black and acid bile, is malignant whenever it is imbued with a saline quality through the action of heat; and this kind is termed “acid phlegm.” Another kind involves air and is produced by dissolution from new and tender flesh. And when this is inflated 83dand enclosed by a fluid, and when as a result of this process bubbles ^note are formed which individually are invisible because of their small size but in the aggregate form a mass which is visible, and which possess a color which appears white owing to the foam created,—then we describe all this decomposition of tender flesh intermixed with air as “white phlegm.”

And the whey of phlegm that is newly formed is “sweat” and “tears,” 83eand all other such humors as pour forth in the daily purgings of the body. And all these are factors in disease, whenever the blood is not replenished naturally from meats and drinks but receives its mass from opposite substances contrary to Nature's laws.

Now, when the flesh in any part is being decomposed by disease, but the bases thereof still remain firm, the force of the attack is reduced by half, for it still admits of easy recovery; 84abut whenever the substance which binds the flesh to the bones ^note becomes diseased and no longer separates itself at once from them and from the sinews, so as to provide food for the bone and to serve as a bond between flesh and bone, but becomes rough and saline instead of being oily and smooth and viscid, owing to its being starved by a bad regimen,—then, every such substance, as it undergoes these affections, molders away beneath the flesh and the sinews 84band withdraws from the bones; while the flesh falls away with it from the roots and leaves the sinews bare and full of saline matter, and by falling back itself into the stream of the blood it augments the maladies previously described.

But although these bodily ailments are severe, still more grave are those which precede them, whenever the bone by reason of the density of the flesh fails to receive sufficient inspiration, and becoming heated because of its moldiness decays and does not admit its nutriment, but, on the contrary, falls back itself, 84cas it crumbles, into its nutriment which then passes into flesh, and this flesh falling into, the blood causes all such maladies to be more violent than those previously described. And the most extreme case of all occurs whenever the substance of the marrow becomes diseased either from deficiency or from excess; for this results in the gravest of diseases and the most potent in causing death, inasmuch as the whole substance of the body, by the force of necessity, streams in the reverse direction.

A third class of diseases takes place, as we must conceive, in three ways, 84dbeing due partly to air, partly to phlegm, and partly to bile. Whenever the lungs, which are the dispensers of air to the body, fail to keep their outlets clean through being blocked up with rheums, then the air, being unable to pass one way while entering by another way in more than its proper volume, causes the parts deprived of respiration to rot, but forces and distorts the vessels of the veins, and as it thus dissolves the body it is itself shut off within the center thereof which contains the midriff; and as a result of this 84ecountless diseases of a painful kind are produced, accompanied by much sweating. And often, when the flesh is disintegrated, air which is enclosed in the body and is unable to pass out brings about the same pangs as those caused by the air that enters from without; and these pangs are most severe when the air surrounds the sinews and the adjacent veins and by its swelling up strains backwards the tendons and the sinews attached to them; hence it is actually from this process of intense strain that these maladies have derived their names of “tetanus” and “opisthotonus.” Of these maladies the cure also is severe for what does most to relieve them is, in fact, an attack of fever.

85aWhite phlegm, also, is dangerous when it is blocked inside because of the air in its bubbles; but when it has air-vents outside the body it is milder, although it marks the body with spots by breeding white scabs and tetters and the maladies akin thereto. And when this phlegm is blended with black bile and spreads over the revolutions of the head, which are the most divine, and perturbs them, 85bits action is more gentle during sleep, but when it attacks persons who are awake it is harder to shake off; and because it is a disease of the sacred substance it is most justly termed “the sacred disease.” ^note Phlegm that is sharp and saline is the fount of all the maladies which are of the nature of catarrhs; and these have received all kinds of names because the regions into which they flow are of all varieties.

All those diseases which are called inflammations, owing to the burning and inflaming of the body which they involve, are caused by bile. This, when it gains an external outlet,
