[Motif] Bi-Lobed Arrow Motif [Description] 
The Bi-Lobed Arrow Motif is often seen in the headdresses of the warriors/birdmen/chunkey players. A complex symbol, it is a graphic representation of a bow and arrow, an atlatl, or possibly a calumet. In the Red Horn Cycle, Red Horn is also called "He who gets hit with deer lungs", which may be a euphemism or an allusion to the fact that deer lungs with the trachea attached, resemble the graphic depiction of the Bi-Lobed Arrow. It may symbolize kinship and adoption rituals related to social hierarchies. Repousse copper examples have been found in Mississippian sites.
