This is a black and white engraving depicting two spheres resting on bases. The sphere on the left is rendered with a network of lines creating a grid-like pattern across its surface, suggesting a representation of latitude and longitude. The sphere on the right is similarly patterned, but the lines are arranged in concentric circles, creating a layered effect. Both spheres are positioned on square bases, which in turn rest on a slightly raised, stepped platform. The image includes cast shadows, adding depth and dimension to the scene. The style is reminiscent of scientific illustrations from historical texts, with a focus on precise lines and geometric forms. The letter 'G.I.' is visible in the upper right corner.
