Gender

Definition

In Hellenistic and traditional Western astrology, gender is a binary classification — masculine or feminine — applied to the twelve zodiacal signs and to the seven traditional planets. The six odd-numbered signs counting from Aries (Aries, Gemini, Leo, Libra, Sagittarius, Aquarius) are masculine; the six even-numbered signs (Taurus, Cancer, Virgo, Scorpio, Capricorn, Pisces) are feminine. Among the planets, Saturn / Jupiter / Mars / Sun are masculine, Moon / Venus are feminine, and Mercury is convertible — taking the gender of whichever planet it most closely conjoins. The classification feeds compound conditions such as ḥayyiz and sect-judgment.

In Tradition

Across the Hellenistic and Arabic-Persian traditions, sign-gender and planet-gender are treated as foundational classifications that compound with sect (diurnal/nocturnal) and hemisphere (above/below the horizon) to produce multi-axis condition diagnostics. Crane preserves the Hellenistic enumeration: 'each [zoidion] is either masculine (Aries, Gemini, Leo, Libra, Sagittarius, Aquarius) or feminine (Taurus, Cancer, Virgo, Scorpio, Capricorn, Pisces).' Sahl's ayyiz condition integrates gender as one axis of a three-axis composite — sect, gender, and hemisphere together.

In Practice

Practitioners use gender in three primary contexts. First, in ease-of-birth and length-of-life judgment: Dorotheus Book 1 Ch. 1.3 reads ease of birth from concordance between the person's gender and the gender of the Sun-Moon-Ascendant sign-set; Mars in a stake especially in a female sign produces sudden birth. Second, in the ayyiz / ḥayyiz composite condition: a diurnal planet above the horizon by day in a masculine sign is in ayyiz, as is a nocturnal planet below the horizon by day in a feminine sign; the composite condition is treated as a strong-condition marker for the planet. Third, in Mercury-complexion delineation: Bonatti's per-Mercury-conjunction framework activates the convertibility doctrine — Mercury takes on the gender (and sect, and moral nature) of whichever planet he most closely conjoins, with 'masculine-with-masculine, feminine-with-feminine' modulating his significations accordingly. Modern Western practice typically softens 'masculine / feminine' to 'active / receptive' or 'positive / negative' but retains the same six-and-six sign alternation.

Historical Origin

The masculine-feminine sign-classification is documented from the earliest Hellenistic Greek sources: it appears in Ptolemy's *Tetrabiblos*, Dorotheus's *Carmen Astrologicum* Book 1 (through ʿUmar al-Tabarī's Arabic), Firmicus's *Mathesis*, and Manilius's *Astronomica*. The Arabic-Persian tradition preserves the same alternation. Bonatti's medieval-Latin compilation systematises the per-planet-gender doctrine, and the convertibility-of-Mercury doctrine (attributed to al-Qabīṣī) is operationalised in *Liber Astronomiae* Vol XI Ch. VI. The six-and-six sign alternation reaches modern Western practice unchanged.
