This is a black and white engraving depicting a grid of nine circular frames, each containing a different geometric shape. The shapes appear to be variations of cubes and polyhedra, rendered with intricate line work and shading to create a sense of depth and volume. The arrangement is divided into two columns, with the left column containing four circles and the right column containing five. Each circle is framed by an ornate, decorative border featuring small floral or leaf-like motifs. The shapes within the circles are complex, with lines converging towards vanishing points to create a perspective effect. Some shapes are simple cubes, while others are more complex polyhedra with multiple faces and angles. The shading and line work create a sense of three-dimensionality, making the shapes appear to be solid objects. At the bottom of the image, there are inscriptions 'B.V.' on the left and 'C.V.' on the right. The overall style of the engraving is reminiscent of Renaissance or Baroque art, with a focus on geometric precision and decorative detail.
