Medieval Catapult Illustration - Historical Siege Engine Design #47727 (License: Personal Use)

This black-and-white line illustration depicts a classic onager-style catapult, featuring a sturdy wooden chassis mounted on four spoked wheels for mobility. The torsion mechanism uses twisted ropes or sinew to store energy in the two vertical arms, which snap forward to launch projectiles from the spoon-shaped bucket at the end of the throwing arm. The drawing emphasizes structural details like mortise-and-tenon joints and bracing, suggesting historical engineering accuracy.
