Jupiter in Sagittarius

Lilly 1659 calls Sagittarius the day house of Jupiter and says he takes joy there, and Raphael 1828 repeats the pairing of house and joy. Lilly gives Jupiter the first eight degrees as terms and the fiery group by night, and he uses Jupiter in Sagittarius as a ready example of a planet in its own house.

The sources describe the sign itself differently. Ptolemy, in Ashmand's 1822 translation, calls Sagittarius and Pisces airy and fruitful because of their trine distance from the houses of the Sun and Moon, while Lilly calls Sagittarius fiery, hot and dry. Adams 1928 uses Greater Fortune, Lilly's older title for the planet, and Heindel 1918 says Jupiter here accents what is good in the sign.

Lilly's condition on any planet in its own house is that it be free of retrogradation, combustion or affliction, three old terms for a planet that moves backward, lies close to the Sun or stands under hard aspect. Modern popular astrology reads expansion, travel, teaching and belief into this pair, which is a modern summary. Jupiter returns to the sign about every twelve years, so people born a dozen years apart often share it.
