An elaborate allegorical woodcut shows the path to knowledge through mathematics. At the base of the image, Euclid stands at the gate of a circular walled garden. He holds a large key and a tablet. Inside the first enclosure, the author Niccolò Tartaglia stands surrounded by figures representing the mathematical arts: Music, Arithmetic, Geometry, Astronomy, and Perspective. On the left side of the courtyard, a cannon fires. A line traces the projectile's trajectory. This represents the new science of ballistics. In the background, steps lead to a second, higher enclosure. Aristotle and Plato stand before a seated figure of Philosophy. A banner above the inner gate bears a Latin inscription. At the top of the frame, two coats of arms flank a central column with more inscriptions.

Let no one ignorant of geometry enter here. original: "NEMO HVC GEOMETRIÆ EXPERS INGREDIATVR"; this is the famous motto attributed to the entrance of Plato's Academy.
