This chapter addresses the extremal latitudes of the planets, the maximum elongation of the inner planets, and the planetary periods. The Moon is said to move a greater distance than do the other planets toward each [side] of the circle through the middle of the zodiacal constellations; next in order is Venus, which goes five degrees to each [side] in its chosen motion, then Mercury (up to four degrees), Mars and Jupiter (up to two-and-a-half degrees), [and] Saturn (up to one degree on each side). Mercury effects [superior] conjunction with the Sun in 116 days when the latter comes in between it [and the Earth]; Venus resumes the same position in relation to the Sun in 584 days, Mars in 780 days, Jupiter in 398, Saturn in 378.

Keywords:   Moon, Sun, Mars, Jupiter, Venus, Saturn, Mercury
