PART 6
But such cities as lie to the west, and which are sheltered from winds
blowing from the east, and which the hot winds and the cold winds
of the north scarcely touch, must necessarily be in a very unhealthy
situation: in the first place the waters are not clear, the cause
of which is, because the mist prevails commonly in the morning, and
it is mixed up with the water and destroys its clearness, for the
sun does not shine upon the water until he be considerably raised
above the horizon. And in summer, cold breezes from the east blow
and dews fall; and in the latter part of the day the setting sun particularly
scorches the inhabitants, and therefore they are pale and enfeebled,
and are partly subject to all the aforesaid diseases, but no one is
peculiar to them. Their voices are rough and hoarse owing to the state
of the air, which in such a situation is generally impure and unwholesome,
for they have not the northern winds to purify it; and these winds
they have are of a very humid character, such being the nature of
the evening breezes. Such a situation of a city bears a great resemblance
to autumn as regards the changes of the day, inasmuch as the difference
between morning and evening is great. So it is with regard to the
winds that are conducive to health, or the contrary.
