This large-scale charcoal drawing shows a group of scholars huddled together during a geometry lesson. A central bald figure leans over a slate on the floor using a compass to measure a diagram, while four students around him observe with varying degrees of comprehension. The visible grid of lines across the paper was used by the artist to transfer the proportions of the drawing to the final wall surface.

This scene represents Geometry, one of the seven liberal arts and a cornerstone of Renaissance natural philosophy. In the Neoplatonic framework of the Stanza della Segnatura, geometry served as the intellectual bridge between the observation of the physical world and the understanding of divine, abstract truths.
