Fortification Wall: Elevation and Angle Plans
A scarped, buttressed wall in perspective with small angular plan sketches below
The e-Leo caption records this inverted page as a fortification study combining an elevation and a plan. The main drawing shows a massive wall in perspective, its long face closely hatched to read as a battered scarp and stiffened by heavy piers or buttresses. Beneath it are several small angular sketches — nested triangles and squares — that appear to work out the plan geometry of the wall's salient angles.

Scarped wall in perspective (elevation)
A long fortification wall is drawn in perspective, its inclined face rendered with dense parallel hatching to show a battered scarp. Vertical piers or buttresses reinforce the front, and a curved sweep at the right suggests a returning flank. It reads as the elevation of a defensive rampart.
Small angular plan sketches
Below the wall are several small studies of nested triangles and squares drawn in outline. They look like quick worked-out plans of the angular salients or corner geometry of the fortification. They are much fainter and smaller than the main elevation above.
