Guñelve
Guñelve (wünelfe in Mapudungun) is a symbol from the Mapuche iconography which can be described as an octagram or a star with eight points.
It represents the planet Venus, but has also erroneously been thought to represent the canelo tree, which is considered sacred among the Mapuches.
The guñelve, also called the "Star of Arauco", was the inspiration of Bernardo O'Higgins to create the current flag of Chile.
Currently the guñelve has been used by many designers, an example of that is the 2015 Copa América in Chile, which was used as the symbol of the cup.
