Zodiac Wheel from Aurora Consurgens

A circular zodiac diagram features twelve compartments surrounding a central blue field where a figure wearing a white headscarf and green tunic sits. The figure’s legs are splayed, clearly displaying the vulva, while they hold a fan-like or vessel-like triangular object. Surrounding this central figure are the twelve signs of the zodiac, including Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius, Pisces, Aries, and Taurus, depicted in alternating colored segments. A golden sun with a face is positioned in the upper right corner, casting rays over the composition.

This illumination is part of the 'Aurora Consurgens', a 15th-century alchemical treatise attributed to Pseudo-Aquinas, which uses biblical and astrological imagery to allegorize the transmutation of base metals into gold. The presence of the female figure in the center of the zodiac emphasizes the feminine principle and the 'menstrual' or transformative cycle central to the alchemical Great Work.
