Trivia: What giant military weapon did Leonardo design?
Three-man sword
Crossbow
Flame thrower
Mechanical horse
Correct Answer: Crossbow
So why is this answer correct? : During his employment as a military engineer, Leonardo da Vinci crafted the designs for a crossbow so large that it took six wheels and a small army of soldiers to maneuver it. Rather than shooting large arrows, the bow was designed to fire large stones — possibly lit on fire — across the battlefield.
