This chapter states that the fixed stars are different from the planets which move within the zodiacal band in a direction opposite to the movement of daily rotation. It also demonstrates what causes different parts of the Earth to be frigid, torrid, and temperate; and why for inhabitants of the contratemperate zone the seasons, that is, the lengthening and shortening of the daytimes, are reversed. The band of the zodiac is at an oblique angle because it is positioned between the tropical circles and equinoctial circle, touching each of the tropical circles at one point, while dividing the equinoctial circle into two equal [parts]. The chapter then illustrates how the planets move in the zodiac, but the Sun, by moving in the heavens through the band between the tropics, necessarily makes torrid the terrestrial band below the interval between the tropics.
