Hellenistic
The astrology of the Greek-speaking Mediterranean from roughly the 1st century BCE to the 7th century CE, as recorded by authors such as Vettius Valens, Dorotheus and Ptolemy.

The tradition lists Taurus as the Moon's exaltation, a high honor in Hellenistic astrology. Hellenistic astrologers count exaltation alongside domicile, the planet's own home sign; medieval astrologers later ranked it immediately below. Taurus is a feminine, fixed earth sign, and the Moon is a feminine, night-team planet, so gender and sect agree. Sect is the tradition's way of sorting the planets into a day team and a night team. In Dorotheus' triplicity scheme the Moon rules the earth signs by night, which adds another line of support. The domicile lord, Venus, is the next planet to examine: its sign, house and dignity show whether the Moon's standing is backed up. The Moon spends about two and a quarter days in each sign. A birth-time error of several hours can therefore move it out of Taurus.

Reviewer's notes
Checked sign element, modality and gender, domicile, exaltation, detriment and fall against the project data and Ptolemy, plus sect and sign relationships; all consistent. Changed: removed the claim that Hellenistic astrologers rank domicile above exaltation, which Ptolemy does not state and which is a later ranking. triplicity lords match the Dorothean table (secondary sources; Carmen Astrologicum itself not opened); gender/sect match claims rest on Ptolemy and a secondary source. Source works confirmed to exist and to treat the topic (Valens Book I opened; others via secondary pages).
