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 da Vinci's birth.
Leonardo's notebook also contained studies of a large
trebuchet used for defending a fortification and trebuchet and catapult
sling release.
