ANAXIMANDER believes that wind is a fluid air, the sun
putting into motion or melting the moist subtle parts of it.
The Stoics, that all winds are a flowing air, and from the
diversity of the regions whence they have their origin receive their denomination; as, from darkness and the west
the western wind ; from the sun and its rising the eastern;
from the north the northern, and from the south the southern winds. Metrodorus, that moist vapors heated by the
sun are the cause of the impetuousness of violent winds.
The Etesian, or those winds which annually commence
about the rising of the Little Dog, the air about the northern pole being more compacted, blow vehemently following
the sun when he returns from the summer solstice.
