Hippocrates De aere, aquis, locis 4

[4] But the following is the condition of cities which have the opposite exposure, namely, to cold winds, between the summer settings and the summer risings of the sun, and to which these winds are peculiar, and which are sheltered from the south and the hot breezes. In the first place the waters are, for the most part, hard cold. The men must necessarily be well braced and slender, and they must have the discharges downwards of the alimentary canal hard, and of difficult evacuation, while those upwards are more fluid, and rather bilious than pituitous. Their heads are sound and hard, and they are liable to burstings (of vessels?) for the most part. The diseases which prevail epidemically with them, are pleurisies, and those which are called acute diseases. This must be the case when the bowels are bound; and from any causes, many become affected with suppurations in the lungs, the cause of which is the tension of the body, and hardness of the bowels; for their dryness and the coldness of the water dispose them to ruptures (of vessels?). Such constitutions must be given to excess of eating, but not of drinking; for it is not possible to be gourmands and drunkards at the same time. Ophthalmies, too, at length supervene; these being of a hard and violent nature, and soon ending in rupture of the eyes; persons under thirty years of age are liable to severe bleedings at the nose in summer; attacks of epilepsy are rare but severe. Such people are likely to be rather long-lived; their ulcers are not attended with serious discharges, nor of a malignant character; in disposition they are rather ferocious than gentle. The diseases I have mentioned are peculiar to the men, and besides they are liable to any common complaint which may be prevailing from the changes of the seasons. But the women, in the first place, are of a hard constitution, from the waters being hard, indigestible, and cold; and their menstrual discharges are not regular, but in small quantity, and painful. Then they have difficult parturition, but are not very subject to abortions. And when they do bring forth children, they are unable to nurse them; for the hardness and indigestable nature of the water puts away their milk. Phthisis frequently supervenes after childbirth, for the efforts of it frequently bring on ruptures and strains. Children while still little are subject to dropsies in the testicle, which disappear as they grow older; in such a town they are late in attaining manhood. It is, as I have now stated, with regard to hot and cold winds and cities thus exposed.

[4] But the following is the condition of cities with the opposite situation, facing the cold winds that blow from between the summer setting and the summer rising of the sun, being habitually exposed to these winds, but sheltered from the hot winds and from the south. First, the waters of the region are generally hard and cold. The natives must be sinewy and spare, and in most cases their digestive organs are costive and hard in their lower parts, but more relaxed in the upper. They must be bilious rather than phlegmatic. Their heads are healthy and hard, but they have in most cases a tendency to internal lacerations. Their endemic diseases are as follow. Pleurisies are common, likewise those diseases which are accounted acute. It must be so, since their digestive organs are hard, and the slightest cause inevitably produces in many patients abscesses, the result of a stiff body and hard digestive organs. For their dryness, combined with the coldness of the water, makes them liable to internal lacerations. Such constitutions necessarily make men eat much and drink little; for one cannot be both a great eater and a great drinker. Inflammations of the eyes occur at last; they are hard and violent, and rapidly cause rupture of the eyes. Men under thirty suffer from violent bleedings at the nose in summer. Instances of the disease called sacred are rare but violent. These men are more likely to be long-lived than are others. Their sores become neither phlegmatic ¹ nor malignant, but their characters incline to fierceness, not to mildness. For men these diseases are endemic, besides there are epidemic diseases which may prevail through the change of the seasons. As to the women, firstly many become barren through the waters being hard, indigestible and cold. Their menstrual discharges are not healthy, but are scanty and bad. Then childbirth is difficult, although abortion is rare. After bearing children they cannot rear them, for their milk is dried up through the hardness and indigestibility of the waters, while cases of phthisis are frequent after parturition, for the violence of it causes ruptures and strains. Children suffer from dropsies in the testicles while they are little, which disappear as they grow older. In such a city puberty is late.
