The Eye of the Imagination (Ars Memoriae)

The engraving shows the left profile of a clean-shaven man in a 17th-century collar, with a prominent eye depicted on his temple. Lines radiate from this eye toward a rectangular grid containing five distinct scenes used as memory aids. Clockwise from the top left, these are: the multi-tiered Tower of Babel, a ship at sea, a scene of the Archangel Raphael leading young Tobias, the Last Judgment with Christ in glory above figures rising from the earth, and a central monolithic obelisk.

This illustration originates from Robert Fludd's 'Utriusque Cosmi Maioris scilicet et Minoris metaphysica, physica atque technica Historia' (1617–1621), a foundational text of Renaissance hermeticism and memory systems that sought to map the human microcosm to the macrocosm.
