Ophiuchus

Definition

A large equatorial constellation between Scorpio and Sagittarius, conventionally identified in Greek-mythological reception with Asclepius the healer. The figure holds Serpens, the celestial serpent, with the two halves Serpens Caput and Serpens Cauda. Ophiuchus crosses the ecliptic plane between Scorpio and Sagittarius but is not one of the twelve zodiacal signs in the canonical Western tradition.

In Tradition

Across the Hellenistic-Hermetic per-degree tradition (Liber Hermetis), the Firmicus-Latin paranatellonta tradition (Bram trans.), and the Arabic-Latin fixed-star tradition (Masha'allah via Dykes), Ophiuchus is read as an extra-zodiacal constellation through stellar positions of its body and through the alpha-star Ras Alhague (Alpha Ophiuchi). The Hellenistic and Arabic traditions treat Ophiuchus paranatellonta-style and through named-fixed-star projection; it has never been incorporated as a thirteenth zodiacal sign in canonical Western practice.

In Practice

Astrologers using paranatellonta technique read Ophiuchus through Liber Hermetis: Ch. III (Scorpio bright-stars) attests 'the one in the right foot of Ophiuchus is in the 20th degree' (Xi/36A/Theta Ophiuchi) and 'the one in the left knee of Ophiuchus is in the 9th degree' (Zeta Ophiuchi); Ch. XXV (Libra paranatellonta) attests 'the head of the Serpent of Ophiuchus (Iota Serpentis, 22°16')'; Ch. XXV (Scorpio paranatellonta) attests 'Ophiuchus and Asclepius + Health + Two Dragons Intertwined (the Caduceus, 8°-10°; making animal-killers, herbalists, physicians, paint-dealers)' and 'the brilliant star of Ophiuchus (Alpha Ophiuchi Rasalhague, 28°16').' Firmicus's Mathesis (Bram trans.) lists 'Ofiuchus' as paranatellonta beside Scorpio with occupational outcomes. Fixed-star practitioners use Ras Alhague projected onto the ecliptic, drawing on the Masha'allah meteorology tradition that reads the star as a drought-breaking rain-indicator when occupying a watery domicile.

Historical Origin

The Ophiuchus paranatellonta + Ras Alhague doctrine is attested in Liber Hermetis Chs. III, XXV (Alexandrian-era Hermetic synthesis, preserved in Zoller's Project Hindsight translation), in Firmicus's Mathesis (Bram trans.), and in Masha'allah's meteorology preserved in the Sahl-Masha'allah Latin transmission (Dykes ed.).

Etymology

Origin: Greek / Latin / Arabic. Meaning: From Greek Ὀφιοῦχος (Ophioûchos, 'serpent-holder'); Latin Ofiuchus / Serpentarius. The Arabic-Islamic tradition names the alpha star raʾs al-ḥawwāʾ ('head of the serpent-bearer'), preserved in medieval Latin transmission as Ras Alhague..
