Muiraquitã

Muiraquitã (Brazilian Portuguese: /mujɾakiˈtɐ̃/, from Tupi mbïraki'tã, "knot of trees", from muyrá / mbyra, "tree", "stick", "wood" and quit, "knot", "wart", "rounded object")[1] is the name given to various types of old artefacts of Amazonian Indigenous origin, carved in stone (primarily jade, nephrite) or wood,[2] and representing animals (especially frogs, but also others such as fish and turtles) or people.

[4] The legend says that the amulet was offered as a gift by the icamiaba [pt] female warriors to all those Indians who annually visited their camp at the river Nhamundá.

At midnight, they dived into the river and brought up a greenish clay in their hands, which they molded into various forms: frogs, turtles or other animals, and presented these to their loved ones.
