Bows (tlahuitolli) up to 1.5 meters (5 feet) long, with animal- sinew or deerskin-thong bowstrings,24 were also major weapons in prehispanic Mesoamerica (see fig. 33), but they were apparently simple rather than compound bows. War arrows (yaomitl) had a variety of points—barbed, blunt, and single pointed of obsidian, flint, or fishbone. During battle, archers kept their arrows in quivers [micomitl or mixiquipilli) (see fig. 3). How many arrows they had is uncertain, but data from elsewhere suggest around twenty per quiver, and archers are invariably depicted with a single quiver. Unlike arrows of Indian groups elsewhere, those in Mesoamerica were not poisoned (despite Huaxtec claims to the contrary), but fire arrows ( tlemitl) were used against buildings.
