Leonardo da Vinci
Leonardo da Vinci demonstrates his propensity for the colossus in his
famous sketch of a giant crossbow. This scan of da Vinci 's
notebook details the laminated bow, winding mechanism and trigger of the
crossbow. Scholars doubt anyone every built this crossbow, but large
bow like siege engines were part of Greek and Roman artillery long before

Leonardo's notebook also contained studies of a large trebuchet used
for defending a fortification and trebuchet and catapult sling release.
da Vinci's crossbow is also featured in the 1903 Ralph Payne-Gallwey
