Siblings, neighbours, short journeys, messages and the familiar environment.
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 3rd zodiac sign for the 3rd house. The historical medical or social judgements in Lilly are evidence of his practice, not present-day advice.
Lilly's list includes brothers, sisters, cousins, neighbours, inland journeys, letters, rumours and messengers. These are not miscellaneous keywords: they are the people and communications close enough to move through ordinary life. His distinction between a small journey here and travel overseas in the ninth gives the pair its practical scale. In a historical question, a letter or messenger can be as important as the relative who sent it.
Paraphrased from Lilly's 1647 list; the period's social and medical vocabulary is documented, not treated as exhaustive or clinically reliable.

The third is cadent and lies in the lower eastern part of the wheel. Lilly names it as the Moon's joy and connects a Moon placed here with movement, especially in a movable sign. That is a judgement made from house, planet and sign together, not a blanket meaning for the third house. It does not inherit Gemini or Mercury simply because the systems each have twelve members.

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 third house
THE Moon in the third house shows native to be changeable and inconsistent in mental pursuits; very curious and inquisitive; fond of enquiring into all kinds of knowledge, ever possessing a fund of information and superficial learning, but lacking in continuity and stability.

Venus in the third house
Venus in the third house is very favourable, giving much love of art and refined literature, poetry, music, painting and all the higher attributes of the mind and mental faculties. The mental qualifications are of the highest, making the mind bright, hopeful, peaceful and harmonious.

Saturn in the third house
SATURN in the third house indicates a despondent, slow and laborious mind ; plodding, careful, cautious and fearful. It favours secrecy, and mental pursuits where tact and patience are required, but much depends upon the nativity as to how Saturn in the third house will affect the mind.

Uranus in the third house
Uranus in the third house denotes an inventive, ingenious, and curious mind; given to study mystical and metaphysical subjects ; unconventional and very liberal mental tendencies ;

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.
