同樣地，「主宰」（commanding）與「服從」（obeying）這兩個名稱，是用來稱呼黃道中這樣的區段：它們以同樣的距離分布於同一個分點星座的兩側，無論該分點星座是哪一個。這是因為它們以相等的時間上升，並且位於相等的緯線上。其中，位於夏季半球的星座被稱為「主宰」，而位於冬季半球的星座則被稱為「服從」。這是因為當太陽位於夏季半球時，白晝長於黑夜；而當太陽位於冬季半球時，白晝則短於黑夜。
Similarly the names “commanding” and “obeying” are applied to the divisions of the zodiac which are disposed at an equal distance from the same equinoctial sign, whichever it may be, because they ascend in equal periods of time and are on equal parallels. Of these the ones in the summer hemisphere are called “commanding” and those in the winter hemisphere “obedient”, because the sun makes the day longer than the night when he is in the summer hemisphere, and shorter in the winter.
