行星也透過所謂的守護宮位、三分區、擢升、界限等關係，以及其他類似的關係，而與黃道各區段具有親和性。宮位的體系，其原理如下。在十二個星座之中，最偏北方、也就是比其他星座更接近我們天頂的，是巨蟹座與獅子座；因此，它們最容易產生熱與溫暖。於是，人們便將這兩個星座分配給最偉大、最有力量的天體，也就是兩個發光體，作為它們的守護宮位：將陽性的獅子座分配給太陽，將陰性的巨蟹座分配給月亮。與此相應，他們又將從獅子座到摩羯座的半圓視為太陽的半圓，並將從水瓶座到巨蟹座的半圓視為月亮的半圓。如此一來，在每一個半圓之中，五顆行星各自都能分得一個屬於自己的星座，其中一個與太陽形成相位，另一個則與月亮形成相位；這種安排同時符合它們運行的軌道以及各自自然性質的特殊特徵。因為土星的本性中以寒冷為主，與熱性相反；而且它所處的軌道最高，也最遠離兩個發光體。因此，便將與巨蟹座和獅子座相對的兩個星座，即摩羯座與水瓶座，分配給土星。另一個理由是，這兩個星座本身具有寒冷與冬季的性質，而且它們與兩個發光體形成直徑相對的相位，這也與土星不具仁慈性的性質相符。接著，將位於土星軌道之下、性質較為溫和的木星，分配給緊鄰前述兩個星座的兩個星座，即多風且多產的射手座與雙魚座。它們與兩個發光體形成三分相，而三分相是一種和諧且有益的配置。再其次，將本性乾燥、所處軌道位於木星之下的火星，分配給緊鄰前述星座的另外兩個星座，即天蠍座與牡羊座；這兩個星座具有與火星相似的性質，並且與兩個發光體形成四分相，這也符合火星具有破壞性與不和諧性的性質。至於本性溫和、位於火星之下的金星，則分得接下來的兩個星座，即極為多產的天秤座與金牛座。這兩個星座保持了六合相的和諧性；另一個理由是，金星無論向哪個方向，都最多只會與太陽相隔兩個星座。最後，水星無論向哪個方向，都不會距離太陽超過一個星座；它的軌道位於其他行星之下，而且在某種意義上更接近兩個發光體。因此，剩下的兩個星座，即位於兩個發光體守護宮位旁邊的雙子座與處女座，便分配給了水星。
The planets also have familiarity with the parts of the zodiac, through what are called their houses, triangles, exaltations, terms, the like. The system of houses is of the following nature. Since of the twelve signs the most northern, which are closer than the others to our zenith and therefore most productive of heat and of warmth are Cancer and Leo, they assigned these to the greatest and most powerful heavenly bodies, that is, to the luminaries, as houses, Leo, which is masculine, to the sun and Cancer, feminine, to the moon. In keeping with this they assumed the semicircle from Leo to Capricorn to be solar and that from Aquarius to Cancer to be lunar, so that in each of the semicircles one sign might be assigned to each of the five planets as its own, one bearing aspect to the p81 sun and the other to the moon, consistently with the spheres of their motion and the peculiarities of their natures. For to Saturn, in whose nature cold prevails, as opposed to heat, and which occupies the orbit highest and farthest from the luminaries, were assigned the signs opposite Cancer and Leo, namely Capricorn and Aquarius, with the additional reason that these signs are cold and wintry, and further that their diametral aspect is not consistent with beneficence. To Jupiter, which is moderate and below Saturn’s sphere, were assigned the two signs next to the foregoing, windy and fecund, Sagittarius and Pisces, in triangular aspect to the luminaries, which is a harmonious and beneficent configuration. Next, to Mars, which is dry in nature and occupies a sphere under that of Jupiter, there were assigned again the two signs, contiguous to the former, Scorpio and Aries, having a similar nature, and, agreeably to Mars’ destructive and inharmonious quality, in quartile aspect to the luminaries. To Venus, which is temperate and beneath Mars, were given the next two signs, which are extremely fertile, Libra and Taurus. These preserve the harmony of the sextile aspect; another reason is that this planet at most is never more than two signs removed from the sun in either direction. Finally, there were given to Mercury, which never is farther removed from the sun than one sign in either direction and is beneath the others and closer in a way to both of the luminaries, the remaining signs, Gemini and Virgo, which are next to the houses of the luminaries.
