Atlatls are ancient weapons that preceded the bow and arrow in most parts of the world and are one of humankind's first mechanical inventions. The word atlatl (pronounced at-latal or atal-atal) comes from the Nahuatl language of the Aztec, who were still using them when encountered by the Spanish in the 1500s. Other words include spear-thrower, estolica (Spanish), propulseur (French), speerschleuder (German) and woomera or miru (English versions of the most common Australian terms).

An atlatl is essentially a stick with a handle on one end and a hook or socket that engages a light spear or “dart” on the other. The flipping motion of the atlatl propels a light spear much faster and farther than it could be thrown by hand alone.
