Astrology & Divination

This intricate diagram, known as a Rashichakra, illustrates the twelve signs of the zodiac and their associated planetary rulers according to Vedic astrology. At its center, a vertical axis shaped like a trident (Trishula) anchors the celestial arrangement, highlighting the interconnectedness of cosmic forces. Such diagrams are essential tools in the study of the Brihat Jataka, a foundational text on horoscopy by the 6th-century polymath Varahamihira.

This diagram represents a traditional North Indian astrological chart, known as a Kundali. It features a square grid divided into twelve houses, used to map the positions of celestial bodies at a specific moment. Such diagrams were essential tools in Jyotish (Vedic astrology) for making predictions and determining auspicious timings.

This plate from Johannes Kepler’s 1619 masterpiece, 'Harmonices Mundi' (The Harmony of the World), illustrates his exploration of geometric forms as the foundation of cosmic order. It notably features the first known depictions of 'Kepler-Poinsot' polyhedra—star-shaped solids—alongside traditional Platonic solids embellished with symbols representing the elements and celestial bodies. Kepler used these complex shapes to argue that the mathematical laws of geometry were the 'archetypes' used by God to design the structure of the universe.

This intricate 13th-century anatomical diagram depicts a human figure with internal organs and a complex network of red lines representing the circulatory or nervous system. It reflects the medieval understanding of human physiology, blending early observational attempts with traditional medical theories of the time.

This is the title page of John Dee's 1564 treatise, 'Monas Hieroglyphica', printed in Antwerp. It features Dee's unique alchemical symbol, the 'Hieroglyphic Monad', which he believed mathematically and symbolically unified all of creation. The symbol is set within a classical architectural frame flanked by the sun and moon, representing the duality of the cosmos, and is accompanied by Latin mottoes emphasizing the need for deep study to understand these hidden mysteries.

This intricate woodcut depicts the 'Jyotishakalpadruma,' or the 'Wish-fulfilling Tree of Astrology.' Rooted in the four foundational Vedas, the tree branches out into the various specialized fields of Indian astronomical and astrological science, such as mathematical astronomy (Siddhanta) and mundane astrology (Samhita). It serves as a sophisticated visual mnemonic, illustrating the vast and interconnected structure of traditional Vedic knowledge systems.

This intricate diagram from a 13th-century medical-astrological compendium illustrates the practice of chiromancy, or palmistry. The two hands are meticulously labeled in Latin, correlating lines and features of the palm with various aspects of a person's life and health. Set against a rich, geometric background, this illustration reflects the medieval belief in the interconnectedness of the human body, astrology, and divination.

This intricate illustration from Michael Scot’s 'Liber Introductorius' depicts the planet Saturn as a crowned king holding a scythe, seated alongside his consort. Below them, the 'children of Saturn'—those whose lives and temperaments are governed by the planet—are shown in various states, reflecting the astrological belief in planetary influence over human destiny. The work serves as a vital record of medieval cosmological thought and the visual tradition of personifying celestial bodies.

This intricate hand-colored volvelle from Peter Apian's 'Astronomicum Caesareum' (1540) is a sophisticated paper instrument designed to calculate the position of the planet Saturn. A divine hand emerges from a cloud at the top, symbolizing the celestial order, while the rotating discs allow the user to simulate complex planetary movements within the zodiac. This work is celebrated as one of the most beautiful and technically advanced examples of 16th-century scientific printing.
