CHAP. 70. (70.)—OF THE OBLIQUITY OF THE ZONES[1].

The three circles[2], which are connected with the abovementioned zones, distinguish the inequalities of the seasons; those are, the solstitial circle, which proceeds from the part of the Zodiac the highest to us and approaching the nearest to the district of the north; on the other side, the brumal, which is towards the south pole; and the equinoctial, which traverses the middle of the Zodiac.
