12 · Why is it that a dry summer and autumn in which northerly winds [15] prevail is unhealthy for those who are bilious? Is it because their bodily condition and the season have the same tendency and it is like adding fire to fire? For the body becoming dry (the freshest element in it becoming evaporated) and being [20] overheated, dry ophthalmia must necessarily ensue owing to solidification;3 but because the remaining humours are full of bile4 and these become overheated, acute fevers must ensue caused by the bile, which is undiluted, and in some cases madness, where black bile is naturally present; for the black bile comes to the [25] surface as the contrary humours are dried up.
13 · Why do they say that a change of drinking-water is unhealthy, but not a change of air? Is it because water becomes nutriment, with the result that it gets into one’s system and has an effect upon one, which is not the case with air? Further there are many kinds of water differing intrinsically from one another, but not of [30] air; this then may also be a reason. For even when we change our place of dwelling we continue to breathe practically the same air, but we drink different waters. It is, therefore, probably a right opinion that change of drinking-water is unhealthy.
[35] 14 · Why is it that a change of drinking-water is more unhealthy than a change of food? Is it because we consume more water than anything else? For water is found in farinaceous and other foods and whatever we drink consists mainly of water.
[861a1] 15 · But why is a change unhealthy? Is it because every change both of season and of age is liable to disturbance? For extremities, such as beginnings and ends, are particularly liable to disturbance. So too foods, when they are different, corrupt one another; for some have only just entered the system, while others have [5] not yet done so. Further, just as a varied diet is unhealthy (for the concoction is then disturbed and not uniform), so those who change their drinking-water are using a varied diet in what they drink; and liquid nourishment has more effect than dry food because it is greater in bulk and because the moisture from the foods themselves forms nourishment.
[10] 16 · Why does a change of drinking-water cause an increase of lice in those who suffer from lice? Is it because, owing to the disturbance set up by the different water in those who frequently change their drinking-water, the unconcocted state of the liquid causes a moist condition, especially in that part where the conditions are suitable? Now the brain is moist, and therefore the head is always the moistest part [15] of the body (as is shown by the fact that hair grows there more than elsewhere), and it is the moisture of this part which generates lice. This is clear in the case of children; for their heads are moist and they frequently have either runny noses or discharge of blood, and persons of this age suffer particularly from lice.
[20] 17 · Why is it that from the rising of the Pleiads until the west wind blows those who suffer from chronic diseases are most likely to die, and the old rather than the young? Is it because two things are fatal to life, excess and cold? For life is heat, whereas this season has both the above characteristics, for it is cold, and winter is then at its height, the subsequent season being spring. Or is it because those who [25] suffer from chronic diseases are in a similar condition to the old? For the occurrence of a long illness is like premature old age, since in both the body is dry and cold,—in the one case owing to the time of life, in the other from disease. Now winter and frosts constitute an excess of coldness and dryness; therefore to those who are in a [30] condition where a very little will turn the scale, winter is like fire added to fire and so causes death.
18 · Why is it that in marshy districts sores on the head are quickly cured, but those on the legs only with difficulty? Is it because the moisture, owing to the fact that it contains an earthy element, is heavy, and heavy things are carried [35] downwards? Thus the upper parts of the body are cleared out because the impurities are carried to the lower parts, and these become full of excretions which easily putrefy.
19 · Why is it that, when a very dry summer follows after northerly winds [861b1] have prevailed in the winter and the spring has been damp and rainy, the autumn is universally fatal, especially to children, while in other people dysentery and prolonged quartan fevers occur then? Is it because, when there is a moderate [5] amount of rain in the summer, the moisture boiling within us, which collected in the damp spring, is cooled and becomes quiescent? If on the other hand this does not happen, children, because they are moist and hot, are in a state of excessive boiling, because they are not cooled; and anything which does not as it were5 boil out in the summer, does so in the autumn. If the excretions do not cause death immediately, [10] but settle round the lungs and windpipe—for they collect first in the upper part of the body, because we are warmed by the air, for it is owing to this that ophthalmia occurs before fever in an unhealthy summer—if then, as I have said, the excretions in the upper parts of the body do not immediately kill the patient, they descend in an [15] unconcocted condition into the stomach; and thus dysentery is caused, because the moisture owing to its abundance is not discharged. If the dysentery ceases, quartan fevers arise in those patients who survive; for the sediment of the unconcocted moisture remains very persistently in the body and becomes active, just like black bile. [20]
20 · Why is it that, if the summer and the autumn have been rainy and damp, the ensuing winter is unhealthy? Is it because the winter finds the body in a very moist state, and also the change from great heat is violent and not gradual, because the autumn as well as the summer has been hot, and so acute diseases are [25] caused in some persons, if they have no rarity in their bodies (for in such persons the moist excretions tend to collect in the upper part of the body, because these parts provide room for them, whereas the lower parts differ in this respect)? Those then whose flesh is solid do not allow of much excretion. When therefore the excretion in [30] the upper parts of the body cools (as happens in drunken persons when they grow cold), the above-mentioned diseases are engendered. On the other hand when fevers are set up in persons in whose bodies there is more rarity, the fevers caused by a large quantity of unconcocted moisture become burning fevers, because in such [35] people the humours are distributed more through the whole body than in solid-fleshed people, and, when the flesh is contracted by the winter-cold, the humours being heated cause fever. For excessive heat in the whole body is fever, and, when it [862a1] is intensified by the abundance of moisture already present there, it turns into a burning fever.
21 · Why is it that when a large amount of vapour is drawn out of the earth [5] by the sun, the year is pestilential? Is it because it is necessarily a sign that the year is damp and rainy and the ground is necessarily damp? The conditions of life will then resemble those under which people live in a marshy district, and these are unhealthy. The body must then have in it an abundance of excretion and so contain unhealthy matter in the summer.
[10] 22 · Why is it that those years are unhealthy in which small toad-like frogs are produced in abundance? Is it because everything flourishes in its natural environment, and these frogs are naturally moist and so signify that the year is moist and damp? Now such years are unhealthy; for then the body being moist [15] contains abundant excretion, which is a cause of diseases.
23 · Why is it that south winds which are dry and do not bring rain cause fever? Is it because they cause alien moisture and heat (for they are naturally moist [20] and hot), and this is what causes fever, for it is due to the combined excess of moisture and heat? When therefore south winds blow without bringing rain, they engender this condition in us, whereas, when they bring rain with them, the rain cools us. Now south winds from the sea are also beneficial to plants, for they are [25] cooled by the sea before they reach them; whereas blight is due to alien moisture and heat.
24 · Why is it that men feel heavier and weaker when the wind is in the south? Is it because moisture becomes abundant instead of scanty, being melted by [30] the heat, and moisture, which is heavy, takes the place of breath, which is light? Further, our strength is
in our joints, and they are relaxed by south winds (as is shown by the fact that things which have been glued together creak); for the viscous matter in the joints, if it hardens, prevents us from moving, whereas, if it is too moist, it prevents us from exerting ourselves.
[35] 25 · Why are people more liable to fall ill in the summer while those who are ill are more liable to die in the winter? Is it because in the winter, owing to the fact that the hot matter from its density becomes collected within the body and we suffer more through the excretions which solidify in us, if we cannot concoct them, the [862b1] commencement of the disease must necessarily be violent, and being of this character it is likely to prove fatal? In the summer on the other hand, because the whole body is in a state of rarity and cool and too much relaxed for great exertion, there must necessarily be many commencements of disease owing to fatigue and to the fact that we do not concoct all that we swallow (for summer is the season of [5] fresh fruit); but such diseases are not so violent, and therefore yield easily to treatment.
26 · Why is it that deaths are particularly likely to occur during the hundred days following each solstice? Is it because in each case the excess of heat or cold extends over this period, and excess causes disease and death in the weakly? [10]
27 · Why is it that the spring and the autumn are unhealthy? Is it because changes are unhealthy? The autumn is more unhealthy than the spring, because we are more apt to contract disease when heat turns to cold than when cold turns to heat, and it is in spring that cold turns to heat and in autumn that heat turns to [15] cold.
28 · Why is it that illnesses are rarer in the winter than in the summer, but more often fatal? Is it because illnesses arise from slight causes in the summer but not in the winter? For in winter we are in a better condition for concoction and at the very height of our health, so that naturally illnesses which arise from more [20] serious causes are themselves more serious and more likely to prove fatal. We see the same thing in athletes and generally among those who are in a healthy condition; for they either are not afflicted with disease, or, if they are, they rapidly succumb, for they only become ill from some serious cause.
29 · Why is it that in the autumn and winter burning fevers are more likely [25] to occur when the weather is cold, while in the summer chills are most troublesome when it is hot? Is it due to the fact that of the humours in man the bile is hot and the phlegm cold? As a result, in summer the cold matter is set free, and being diffused in the body gives rise to chill and shivering; in the winter, on the other hand, the hot [30] matter is overpowered by the weather and cooled. Burning fevers are more troublesome in the winter and autumn, because, owing to the cold, the hot matter collects within, and the fever is within and not on the surface; it is natural therefore that burning fevers should occur during this part of the year. This can be well illustrated by contrasting those who bathe in cold water and those who use warm [35] water in the winter; those who wash in cold water, though they feel chilled for a short time while they are actually washing, suffer no ill effects from the cold during the rest of the day, while those who use hot water continue to be less able to resist [863a1] the cold. For the flesh of those who wash in cold water becomes solid, and the hot matter collects within; but the flesh of those who use warm water becomes rare, and the hot matter is diverted to the outside of the body. [5]
30 · In what does the virtue of a poultice consist? Would it, owing to its dissolvent action, set up perspiration and evaporation?
31 · How can the presence of an abscess be diagnosed? Is it true that, if, when hot water is poured over it, a change takes place, there is an abscess, but none if there is no change?
[10] 32 · In what cases ought cauterization to be employed, and in what cases the surgeon’s knife? Is it true that wounds which have large openings and do not close up quickly ought to be cauterized, so that a scab may form? If this is done, there will be no festering.
33 · In what does the virtue of a remedy for stanching blood consist? Is it because it has a drying effect and stops the discharge of excretions without making [15] a scab or causing decay of the flesh? If so, the wound must be free from inflammation and likely to heal up. For if there is no discharge, it will be free from inflammation, and being dry it will close up; whereas it will not close up as long as it is discharging moisture. Most remedies, therefore, for stanching blood are pungent, so as to cause contraction.
[20] 34 · When ought drugs to be employed and not the knife or cauterization? Ought drugs to be used for the armpits and groin? For sores in these parts are sometimes painful and sometimes dangerous after they are cut open. Flat growths and those which project considerably and are situated in parts which are venous and not fleshy, should be cauterized; but those which collect at an acute point and are not situated in solid parts of the body should be treated with the knife.
[25] 35 · Why is it that, if one is cut with a bronze instrument, the wound heals more quickly than if the cut is made with iron? Is it because bronze is smoother and so tears the flesh and bruises the body less? Or must we reject this explanation, since, if iron takes a better edge, the cleavage is easier and less painful? Yet even so bronze has a medicinal power of its own, and it is the beginning that is important, and so the drug, by its immediate action as soon as the cut is made, causes the [30] wound to close up.
36 · Why is it that burns inflicted by bronze heal more quickly than others? Is it because bronze contains more rarity and is less substantial, and the more solid a thing is the more heat it contains?
37 · Is barley-gruel lighter and better for use in sickness than that made from wheat? For the latter commends itself to some people who argue from the fact [863b1] that among bakers those who handle wheaten flour have a much better colour than those who employ barley meal, and furthermore that barley is moister and that which is moister requires more concoction. But is there any reason why barley should not have some qualities which make it more difficult of concoction and [5] others which make it more serviceable because of its lightness? For barley is not only moister than wheat, but it is also colder, and porridge and any other food which is served to one who is in a fever ought to be such that it will provide him with a little nourishment and also cool him. Now barley-gruel has these qualities; for, because it is moist rather than substantial, it gives nourishment which is small in bulk and at the same time has a cooling effect. [10]
38 · Why do purslane and salt stop inflammation of the gums? Is it because purslane contains some moisture? This is seen if one chews it or if it is crushed together for some time; for the moisture is then drawn out of it. This glutinous matter sinks into the gum and drives out the acidity. For that there is an affinity between the disease and the remedy is shown by the acidity; for the juice of purslane [15] has a certain acidity. Salt on the other hand dissolves and draws out the acidity. Why then do lye and soda not have this effect? Is it because they have an astringent instead of a dissolvent action?
39 · Why is it that fatigue must be cured in summer by baths, in winter by anointing? Is anointing employed in the latter case because of the cold and the [20] changes which it causes in the body? For the fatigue must be got rid of by heat which will warm the body, and olive-oil contains heat. In summer, on the other hand, the body requires moisture, because the season is then dry and chills are not to be feared, because the natural inclination is towards heat. A sparing diet of solid food and a liberal indulgence in liquid nourishment are appropriate to the summer, [25] the latter being peculiar to summer, while the former is commoner then than at other seasons; for indulgence in drinking is peculiar to the summer because of the dryness of the season, but a sparing diet is found at all seasons but is more general in the summer; for then, owing to the weather, heat is engendered by food.
40 · Why do some drugs relax the stomach and not the bladder, others the [30] bladder and not the stomach? Is it true that anything which is naturally moist and full of water, if it has medicinal properties, relaxes the bladder? Fo
r it is there that the unconcocted moisture settles; for the bladder is a receptacle for any moisture which is not concocted in the stomach; and such moisture does not remain there, but passes away without undergoing or causing any change. But anything which partakes of the nature of earth, if it has medicinal properties, relaxes the stomach; [864a1] for it is to the stomach that anything of an earthy nature is carried, so that, if it has any motive power, it causes a disturbance in the stomach.
41 · Why is it that some things affect the upper part of the stomach, hellebore for example, others the lower part, for instance scammony, while others like elaterium and the juice of thapsia affect both parts? Is it because some of the [5] drugs which affect the stomach are hot and others cold, so that some of them, owing to their heat, as soon as they reach the upper part of the stomach are carried thence to the upper region of the body, melting in particular anything there which is most alien to them and least substantial; and if the drug be powerful or has been administered in a dose stronger than nature can withstand, it carries these [10] liquefactions and any excretions that there may be down into the upper part of the stomach, and by its heat stirring up the breath, which it engenders in great quantity, checks their progress and causes vomiting? Drugs of a cold nature, on the other hand, owing to their weight are carried downwards before undergoing or causing [15] any change and, borne thence, have the same action as those which affect the upper part of the body; for passing thence upwards through the ducts and setting in motion any excretions or liquefactions over which they prevail, they carry them with them in the same direction. Drugs which partake of both these kinds and are a [20] mixture of hot and cold, possessing both qualities, have both these effects, and are the composite drugs which doctors now make up.
