But it is the sea which divides as it seems the parts beyond India
from those beyond the Pillars of Heracles and prevents the earth from
being inhabited all round.

Now since there must be a region bearing the same relation to the
southern pole as the place we live in bears to our pole, it will clearly
correspond in the ordering of its winds as well as in other things.
So just as we have a north wind here, they must have a corresponding
wind from the antarctic. This wind cannot reach us since our own north
wind is like a land breeze and does not even reach the limits of the
region we live in. The prevalence of north winds here is due to our
lying near the north. Yet even here they give out and fail to penetrate
far: in the southern sea beyond Libya east and west winds are always
blowing alternately, like north and south winds with us. So it is
clear that the south wind is not the wind that blows from the south
pole. It is neither that nor the wind from the winter tropic. For
symmetry would require another wind blowing from the summer tropic,
which there is not, since we know that only one wind blows from that
quarter. So the south wind clearly blows from the torrid region. Now
the sun is so near to that region that it has no water, or snow which
might melt and cause Etesiae. But because that place is far more extensive
and open the south wind is greater and stronger and warmer than the
north and penetrates farther to the north than the north wind does
to the south.

The origin of these winds and their relation to one another has now
been explained.
