Good day dear Ms. Hamilton,
Thank you once again for the useful information provided. My own approach is to maintain an open mind ("The Way is the goal") rather than seeking a one and only Salvatory School of Astrology. The table you provided a link to was already familiar. The hypothesis of deduction of the Trigon Ladyships and Lordships from the Zoidia of Exaltation does not appear to explain the portion (degree) (not merely Zoidion) positions of the Exaltations of the wandering Stars in that very table.
These portion positions were an enigma until the (often, alas, ignored) work of the 20th century Irish astrologer and author Cyril Fagan. The combination of Babylonian New Year 27 March 786 BCE GC (new Moon Crescent sighted after vernal equinox) with the heliacal rising of Aphrodite (Ishtar, Most Revered Goddess) the following morning was quite extraordinary. Hermes was not visible at New Year but, if you like, we can also show His first heliacal rising in that year. The exaltation of Ares was at His position at His first heliacal rising on 23 January 785 BCE GC in the same Babylonian year. Here are two charts (both using a fixed zodiac set at the Fagan-Bradley precession factor) illustrating the portions (degrees) of the Exaltations:
It seems that, indeed, parts of Mesopotamian astrology found their way into the Hellenistic system, perhaps also the 'winds'. It might be interesting to examine even more closely how much the concept of 'winds' differs from that of 'elements'.
Best regards,
