Cadent house

The idea of numerological correspondences goes back at least as far as Pythagoras and was surely instrumental in the interpretation by ancient astrologers of the angular relationships each house has with the others, and especially with the Ascendant.

But the "natural houses" doctrine stretches these similarities to a point which seriously distorts the original concepts.

The house was also the place of religious cults, particularly unconventional ones (possibly what we would now call the "occult") and had nothing to do with writing or speaking.

Valens makes a clear connection between this house and thieves, beggars, foot soldiers, and slaves.

It seems (according to this page) it is not sure in which category the philosophy of Mars in the sixth house belongs: is it the Christian, modern, etc.

[13] Medieval astrologers connect it with the Church and clerics, long sea voyages, books, learning, philosophy and dreams.

[14] This connection with dreams is quite ancient, and references to the ninth house in this capacity can be found in Firmicus and in Paulus Alexandrinus.

[16] Paulus claims that an otherwise strong Saturn located here will bring success over enemies and joy in work.

It is from medieval astrologers that the connection of the twelfth house with imprisonment derives;[20] the idea is probably Arab in origin.

Modern astrologers have brought a spiritual aspect to the twelfth house that was wholly absent in the earlier tradition.

In Jyotish (Hindu astrology), the twelfth house is very unfortunate but is also connected with sexual activity[21] and with spirituality.

Much has been made of this suggested affinity by some modern astrologers, especially those influenced by the 19th-century Theosophy movement, such as Annie Besant and Alice Bailey.
