Technical diagram of a multi-tiered siege engine or lifting machine.

This woodcut diagram illustrates a complex multi-tiered siege engine, reflecting the advanced military engineering of the late 16th century. The detailed rendering shows the internal structural supports and wheels, providing insight into the mechanical designs described by Hero of Alexandria and translated by Francesco Barocci.

Technical diagram of a multi-story siege tower on wheels with internal ladders.

This woodcut illustrates a multi-story siege tower, a formidable engine of ancient warfare described by Hero of Alexandria. The diagram meticulously details the internal framework, including ladders for soldiers to ascend and wheels for mobility, reflecting the Renaissance fascination with recovering and visualizing classical military technology.

diagram
Technical diagram of a mechanical component, likely part of a catapult or ballista, with alphabetical labels for reference in the text.

This technical diagram illustrates a component of an ancient war machine, as described by Hero of Alexandria. The use of alphabetical labels allows the reader to follow the complex mechanical explanations in the accompanying Greek and Latin text. Such illustrations were crucial for the early modern rediscovery and reconstruction of classical engineering feats.

diagram
Detailed technical engraving of a canal lock system with boats and architectural structures.

This intricate engraving illustrates a sophisticated canal lock system designed for river navigation, likely from Agostino Ramelli's 'Le diverse et artificiose machine' (1588) or a similar engineering treatise. The scene depicts three boats within a circular basin, managed by massive wooden gates and surrounded by supporting structures and workers, showcasing the advanced hydraulic engineering of the late 16th century. The use of lettered labels (A-F) indicates its function as a technical diagram intended to explain the mechanical operation of the lock.

engraving
Engraving of the 'Carro delle Zaffosina' showing technical diagrams and a perspective view of the machine in operation.

This intricate engraving from Vittorio Zonca’s 1607 treatise illustrates the 'Carro delle Zaffosina,' a specialized mechanism designed for heavy transport. The plate masterfully combines technical plan views of the machine's components with a dynamic perspective scene showing the device in operation within a riverside structure, exemplifying the sophisticated mechanical engineering of the early 17th century.

engraving
Technical diagram of a hydraulic organ (hydraulis) showing pipes, water tank, and pumping mechanism.

This technical drawing illustrates the hydraulis, or water organ, an ancient musical instrument powered by water pressure. Attributed to Hero of Alexandria, this diagram demonstrates early sophisticated understanding of pneumatics and hydraulics, preserved here in a 16th-century Greek manuscript.

diagram
Technical diagram of a gastraphetes (belly-bow), an ancient Greek siege engine.

This woodcut diagram illustrates a gastraphetes, or 'belly-bow,' an early form of crossbow described by Hero of Alexandria. The drawing meticulously details the mechanical components, including the sliding mechanism and the bow, serving as a visual aid to the technical Greek and Latin text.

Hero of Alexandria built steam-powered automata. Archimedes calculated the mathematics of levers and spirals. Vitruvius codified Roman architecture. Frontinus documented the Roman water supply. These texts were lost, rediscovered, and translated in the Renaissance — where they sparked the engineering revolution. This collection gathers the ancient originals alongside their Renaissance recoveries.
