This is a black and white engraving depicting a complex geometric pattern surrounded by clouds. The central design is a series of nested shapes. At the very center is a small square, followed by a circle, then an octagon, and finally a larger square. These shapes are all aligned with their corners and sides parallel to each other. Around the central square is a circular border, and beyond that, a series of radiating lines that create a star-like effect. The entire design is framed by a rectangular border. At the top and bottom of the image, stylized clouds are depicted, adding a decorative element. In the lower right corner, there is some text written in a script that appears to be French, reading '21. Figure. Cosmique'. The style of the engraving suggests it is an older illustration, possibly from a scientific or alchemical text.
