Leonardo da Vinci Sketches the Design for a Scythed Chariot

The scythed chariot is potentially one of the most lethal battlefield weapons and has ancient origins, though Leonardo noted their propensity to damage friend as readily as foe. The drawing for these war machines dates from his first years in Milan.

In Renaissance times, war was the order of the day and war machines were at the centre of interest not only for their practical use but also from a cultural point of view, with the rediscovery of inventions from classical times.
