The second question of “Ye Quizze” tested your knowledge of the Trutine of Hermes. None of the multiple choice questions was right. I chose this particular technique as the name is exotic enough to attract the attention of any traditionalist! 😉
So what is the Trutine? It is basically an axiom which expresses a reciprocal relation between Asc/Desc and Moon for the time of conception and the time of birth:
The Ascendant or Descendant at conception is the position of the Moon at birth just as the position of the Moon at conception is the Ascendant or Descendant at birth. It is reciprocal:
Asc or Desc / Moon (Conception) = Moon / Asc or Desc (Birth)
The word trutine is I think a corruption of the latin trutina, which means a balance or set of scales. It is obvious why! The Moon is the central generative planet and the horizon is pregnant with birth symbology!
The 51st Centiloquium of Ptolemy describes it thus:
“In what sign the Moon is at the time of birth, make that sign the ascendant in conception; and in what sign she is found at the conception, make that or its opposite the sign ascending at the birth.”

Here are two charts where only the Moon is shown to demonstrate this:
Notice that the Ascendant in the Conception chart is at 26 deg 09 Virgo. The particular chart this was taken from had a known time of birth. The original chart has 22 Libra 20 on the Ascendant and the Moon at 26 Pisces 09. The tables Lilly gives in “Christian Astrology” give only an approximation of the gestation time. One has to look at the ephemeris for the exact day. In this particular case it was 2 days off. Now if the original chart had been rectified according to this method there would have been 9 minutes difference in the time. Nine minutes is fairly close, but is it exact enough?
