A house does not have a fixed zodiac sign or planetary ruler in this reference. Those popular correspondences collapse two different twelvefold systems and are not needed to read an actual cusp.

Reading this house
Lilly's topics below tell you what kinds of question this place was used to answer in seventeenth-century astrology. Its position in the wheel is a different piece of information. For an actual chart, read the sign on the cusp, its ruler, any planets here and their aspects together; do not substitute the 9th zodiac sign for the 9th house. The historical medical or social judgements in Lilly are evidence of his practice, not present-day advice.
Lilly gives the ninth voyages beyond seas, foreign countries, clergy, dreams, visions, books and learning. The older account is not limited to formal education or to belief as an inner opinion; it includes institutions, texts and journeys that take a person beyond the nearby world of the third house. A dream in a seventeenth-century horary question and a university course in a modern natal reading do not have identical evidential standing, though both draw on this inherited house vocabulary.
Paraphrased from Lilly's 1647 list; the period's social and medical vocabulary is documented, not treated as exhaustive or clinically reliable.

Christian Astrology — Book I, chapter VII, ‘Of the Twelve Houses of Heaven’ (9th house)
The ninth is cadent from the Midheaven. Lilly gives the Sun a joy here and Jupiter a special association in his religious examples. That planetary joy is a distinct traditional device, not a fixed planetary ruler of the ninth. Neither means that any ninth-house planet automatically makes a traveller or believer. The comparison with the third is useful: short, local messages there; distant travel and larger systems of knowledge here. Sagittarius is not permanently on the ninth cusp.

Opinions, not this study's and not findings. These were published around 1900 by astrologers writing for a Theosophical readership, and most English astrology since has been reading them. They are quoted rather than restated so the distance stays visible, and each one names its astrologer and its page.
Moon in the ninth house
Moon in the ninth house denotes a keen imagination, a mind receptive to higher thought ideals, and the ability to study or understand metaphysical subjects. It gives a love for travel and denotes many changes in the life and those chiefly of a beneficial and improving nature. If afflicted: by Mars, affects the religious tendencies, either giving over-enthusiasm, or peculiar and unorthodox views;

Mercury in the ninth house
Mercury in the ninth house denotes a love of knowledge, an enquiring and studious mind. Unless well aspected this position is not altogether favourable, but if the horoscope indicates power to concentrate, the position is improved. If afflicted it denotes a tendency to worry, and to become engaged in too many things ai one time, also to wander and take aimless journeys.

Mars in the ninth house
Mars in the ninth house denotes an over-enthusiastic nature with regard to religious and philosophical subjects, and tends to destroy reason or to allow impulse and desire to overrule the mind. If much afflicted it gives fanatical, irregular, bigoted or sceptical opinions on religious matters; if well aspected a zealous and enterprising mind.

Jupiter in the ninth house
JUPITER in the ninth house is the ideal position for the philosopher or saint, unless afflicted, when religious fervour and devotion will take the place of philosophy of the metaphysical order. If afflicted: by Mars, a tendency to go to extremes in religious matters, also legal troubles and danger of shipwreck or accidents abroad ;

Saturn in the ninth house
SATURN in the ninth house denotes a studious and meditative mental attitude towards all higher thought pursuits. It favours the scientific and philosophical more than the religious mind and often causes the native to investigate astrology, metaphysics, and psychic studies generally.

A planet missing from this list is one Leo does not delineate in this house, or one whose passage did not survive its own scan.
Who is quoted here, and who is not
Two astrologers, both writing around 1900:
Alan Leo, whose How to Judge a Nativity is the only
one of these books arranged as a lookup table — a paragraph per planet per
house — which is why everybody copied it; and Sepharial, who
arranged the same material by the question a reader brings rather than by
placement, so only a few of his judgements stand alone well enough to quote.
William Lilly is not here, and not because he was not asked.
Christian Astrology (1647) is the most important book in English on
the subject and this study holds it as a text already — but every scan of it is
long-s blackletter, and the OCR renders the title of its own first book as
“An Introduci ion to Aftrologje”. There is
nothing in it a reader could trust a quotation from. Ripley's
Compound of Alchymy and Anderson's Constitutions get
the same answer elsewhere in this study, for the same reason.
