The Mãe-do-Ouro (lit.
'Mother of Gold') is a Brazilian mythological figure primarily known in the folklore of the interior of the Brazilian Southeast, Northeast, and Center-West regions.
[1] Depending on the region, this figure takes the form of either a beautiful blonde woman that wears a silk dress or a fireball that has the ability to transform itself into the former.
[2] Her appearance is said to indicate areas where gold and precious minerals should not be exploited.
[3] The origins of the Mãe-do-Ouro date to the 18th century Brazilian Gold Rush.
