_Son._ These things are all clear to me and it seems reasonable that they should be as you say. Still, there are a few things that you mentioned a little earlier in your talk, which I wish to ask about, if you permit. You said that both sides of the earth are cold, the southern as well as the northern. But I hear it said by all men who come from the regions to the south that the farther south one travels, the hotter the lands are. Likewise all the winds that come from the south are both moister and milder than other winds. In the winter those winds always bring a good thaw, while other winds are so cold that they bring frost, and ice is formed. And during the summer the south wind is still warmer than other winds. Now if my questions do not tire you and I do not seem to ask too much, I should like to have you answer this question too. _Father._ When I told you that in the skies three belts are traced under which it is difficult to cross, one torrid and two frigid, I added that the hot belt curves from east to west. But if I have stated this correctly, it will be evident that the cold must be as severe in the southern parts as in the northern.[232] I believe, however, that all the regions lying near the hot belt, whether on the south side or on the north, are also hot; but I believe those lands to be frigid which lie very far in either direction. You have stated that all men tell us that the farther south one travels, the greater the heat; but that, I believe, is due to the fact that you have never found any one who has traveled as far south of the hot belt as those lands which we have now talked of lie to the north. You have also said that the winds which come from a southerly direction are warmer than the rest. But it is reasonable that the south wind should be warm when it reaches us, even though it comes from the frozen south side of the earth, for it blows through the curved ring of the torrid belt.[233] Consequently, though it blows cold from the south, it is warm when it emerges on the northern side. And if people live as near the cold belt on the southern side as the Greenlanders do on the northern, I firmly believe that the north wind blows as warm to them as the south wind to us. For they must look north to see the midday and the sun’s whole course, just as we, who dwell north of the sun, must look to the south. Footnote 232: Cf. _Macrobius_, 601. “... for both the northern and the southern extremities lie stiff with perpetual frost, and they are like two zones with which the earth is girdled, but narrow as if they were circlets drawn about the farthest regions.” Footnote 233: Macrobius states the same belief in quite similar terms: the south wind comes from a frozen clime just as the north wind does; but “since it comes to us through the flames of the torrid zone and mixes with the fire, it becomes hot, so that what was cold in the beginning comes to us with warmth.” (P. 603.)
