Leonardo da Vinci designed a scythed chariot with rotating blades mounted on an axle.
The concept belongs to Leonardo’s military studies and adapts the ancient idea of a chariot fitted with scythes. As the vehicle moved, the rotating axle would carry blades through the area beside the chariot, threatening soldiers and disrupting formations. Leonardo’s version included a mechanical arrangement intended to make the blades rotate as the vehicle advanced.
The design is often associated with Leonardo because his drawings and descriptions show a Renaissance attempt to analyze and improve an ancient weapon. It was not the same as a standard horse-drawn chariot, whose wheels simply supported the vehicle. The added rotating mechanism was the defining feature of Leonardo’s proposal.
There is no reliable evidence that Leonardo’s scythed chariot was built or used in combat. Ancient scythed chariots had already existed centuries earlier, especially in parts of the ancient Near East, so Leonardo should be credited with a redesign or study rather than with inventing the weapon category itself.
