Modern blueprint-style educational illustration of an ancient ONAGER siege engine. Deep blue grid background with clean white technical line art. Clearly non-functional, abstract schematic, not to scale. Two views shown: top view and side view. The onager is positioned horizontally. Labels include: Torsion bundle, Throwing arm, Frame, Winch. Minimal text, no measurements, no construction instructions. Museum-style technical diagram, high contrast, consistent with modern engineering blueprints. Voir plus
