Sect in Astrology: Day and Night Charts

Sect in Astrology: Day and Night Charts

In episode 274 of the podcast Chris Brennan gives a detailed overview of the concept of sect in astrology, which is the difference between day and night birth charts.

Sect is a fundamental concept that was used in Hellenistic astrology, but it has only been recovered by contemporary astrologers over the past 30 years through translations of ancient texts.

The purpose of this talk is to give a broad introduction to sect, first by establishing how pervasive the concept is in ancient astrology, and then to demonstrate how it works in practice through chart examples.

This episode was recorded as a live stream with an audience of patrons who support the podcast through our page on Patreon each month:

  • Loved this episode and really helped me understand more about Sect.
    And why I feel more aligned with my Moon sign than my Sun sign.
    My question is though, I have my chart ruler Jupiter (Pisces Rising) conjunct Saturn (Night Chart) in my 8th house Libra and they both square Mars in the 5th house Cancer. Moon is also Conjunct Mars. Sun in Leo 6th house.
    Does Jupiter soften Saturn?

    • A little bit yes, although Venus would have more power to soften Saturn in a night chart than Jupiter would, if she was configured. Saturn being in the sign of its exaltation is a mitigating factor as well.

      • Thank you. I have Venus in my 7th house Virgo which semi sextile’s Saturn and Jupiter.
        Hadn’t thought to look at it with Venus yet. All I knew was that Venus is in its fall there.
        I’ve been listening to your podcast since July, so glad I found it during our hard lockdown here in Australia and have loved listening to it on my walks. Your mentioning of your book wired as I bought it and it arrived yesterday!
