This article records tradition as it has been passed down and reported. Its sources are not yet part of the atlas's verified catalogue.
A person entry records how the classical and horary astrological tradition assigns significance for a specific family relationship, a father, mother, spouse, child, sibling, servant or uncle, to a particular planet or pair of planets and a particular house of the chart, following the tradition's own logic rather than a modern invented scheme: the father is read from the day sect pair, the Sun and Saturn, and from the fourth house in the classical reading or the tenth in a reading modern practice increasingly prefers, while the mother is read from the night sect pair, the Moon and Venus.
An entry records both a significator's classical assignment and, where the two genuinely differ, the specific alternative modern practice has adopted, naming both readings honestly as documented positions within an ongoing tradition rather than presenting one as having simply replaced the other.
William Lilly's own seventeenth century textbook is the classic working statement of this significator system in English, and an entry draws on it for the documented logic connecting a family relationship to its planet and house, the sect based pairing of Sun and Saturn against Moon and Venus foremost among that logic's own stated reasons.
