This black-and-white line illustration depicts a classic Roman-style semicircular arch constructed from wedge-shaped bricks (voussoirs), arranged radially around a central axis. The keystone at the apex locks the structure in place, demonstrating fundamental principles of compressive force transfer in masonry. The hand-drawn texture adds authenticity, evoking historical architectural manuals and engineering textbooks.
