This woodcut depicts a male figure inscribed within a square, illustrating the Renaissance concept of the human body as a perfectly proportioned microcosm. The figure is marked with a cross on the abdomen and surrounded by symbolic elements, including an eye above and a serpent to the left, suggesting a deeper alchemical or philosophical meaning. This image reflects the early modern fascination with the intersection of geometry, divinity, and the human form as described in occult and anatomical treatises.

This woodcut from Albrecht Dürer's 'Four Books on Human Proportion' illustrates his rigorous, mathematical approach to depicting the human body. The page shows a female figure from both frontal and profile perspectives, overlaid with a complex system of measurements and labels that define ideal anatomical ratios. Published posthumously in 1528, this work represents the culmination of Dürer's lifelong quest to find a geometric basis for beauty and form.

This woodcut portrait depicts Gabriel de Collange, the French translator of Trithemius's 'Polygraphia,' at the age of 37. He is shown surrounded by the tools of his trade—mathematical instruments and scrolls with moralizing Latin mottos—emphasizing the intellectual and scientific nature of his work on secret writing.
This intricate diagram illustrates the concept of the 'Microcosm,' representing the human being as a reflection of the greater universe. The male figure is precisely positioned within a circle, square, and pentagram, with planetary symbols placed at key points to demonstrate the perceived harmonic correspondences between the human body, geometry, and the celestial spheres. Such imagery was central to Renaissance and early modern philosophical and alchemical thought.
This woodcut depicts the human figure as a microcosm, a central theme in Renaissance occult philosophy. Standing on a cube (representing the material world) and enclosed within a circle (representing the celestial realm), the figure holds pentagrams, symbolizing the harmony between the human form and the divine order of the universe. This illustration is famously associated with Heinrich Cornelius Agrippa's influential work on occult philosophy, illustrating how the human body reflects the proportions of the cosmos.
This engraving illustrates the concept of 'La Philosophie' through the lens of human proportion and sacred geometry. A male figure is depicted within a circle, his outstretched arms holding pentagrams, symbolizing the microcosm's relationship to the macrocosm. The accompanying French text discusses the 'square measure' of the human body, a theme common in Renaissance and early modern architectural and philosophical treatises that sought to find divine order in the human form.
This woodcut from Heinrich Cornelius Agrippa’s seminal work, 'De Occulta Philosophia', illustrates the concept of man as a microcosm. A male figure is depicted within a circle, standing upon a cube and holding pentagrams, symbolizing the divine proportions and the integration of the human form with the celestial and terrestrial realms. This image is a quintessential example of Renaissance occult thought, blending geometry, anatomy, and mysticism.
This woodcut depicts a male figure inscribed within a circle and a pentagram, illustrating the Renaissance concept of the human body as a microcosm of the universe. Astrological symbols are placed at the extremities and center, linking human anatomy to celestial influences and geometric perfection. This image is a quintessential example of early modern efforts to harmonize science, art, and occult philosophy.

This woodcut from Albrecht Dürer's seminal 1528 treatise on human proportion demonstrates his rigorous, mathematical approach to anatomical study. By presenting the female form in both frontal and profile views with precise measurement scales, Dürer sought to establish a scientific basis for artistic representation. This plate is a prime example of how Renaissance artists used empirical observation and geometry to understand the natural world.
Heinrich Cornelius Agrippa, Johannes Trithemius, Paracelsus, Albrecht Dürer — the network of Renaissance polymaths around the upper Rhine. Agrippa's De Occulta Philosophia synthesized the entire Western magical tradition. Trithemius invented steganography. Paracelsus reinvented medicine. This is their world.
