Konrad Kyeser Writes Bellifortis
1404
The Bavarian military engineer produced the most comprehensive illustrated treatise on warfare technology yet compiled in Europe. Its lavish pages depicted siege engines, incendiary devices, diving suits, and chariots armed with rotating scythes in exquisite detail. Some designs were wildly fanciful; others anticipated Renaissance military engineering by decades. The manuscript circulated among German princes and their arsenals, shaping a generation of fortress design.
