The crossbow, a weapon popular with some modern hunters, looks like a cross between a bow and a rifle. Like a bow, it uses a fast-moving string to launch projectiles, but it also has a trigger and a stock, like a rifle. Based on these similarities, some people may think that the inventor of the crossbow took pieces from a rifle and attached them to a bow.

But crossbows have been around much longer than guns have. Archeologists have found crossbows in 2,500-year-old Chinese graves, and some historians believe that they existed in China as early as 2000 B.C. Crossbows also appeared in the Mediterranean region by the fourth century A.D. Roman military writer Flavius Vegetius Renatus mentions them in a text written in 385 AD, and they were prevalent in Europe throughout the Middle Ages.
