Jupiter in Capricorn

Fall means the sign across from a planet's exaltation, and Capricorn stands opposite Cancer, so Lilly 1659 and Ptolemy (Ashmand's 1822 translation) agree it is the fall of Jupiter. Nothing in that word describes a person. Mars is exalted in this same sign, which makes Capricorn the meeting point of two opposite placements.

Lilly also assigns Jupiter the first ten degrees as face and degrees 13 to 19 as terms, so the table still leaves him small allotments. The sign is cold, dry and earthly in his description, opposite to a hot, moist planet on both qualities. Saturn owns the house, and Ptolemy places Jupiter between the extreme cold of Saturn and the burning heat of Mars.

Adams 1928 remarks only that Jupiter on the Ascendant in this sign would broaden the features, a physical note with no moral weight. Modern popular astrology tends to describe cautious, conservative aims and a faith in structure and long effort. Read those as modern suggestions.
