I have had for many years an artifact - present from someone from Peru What god is that?

Question

Quetzalcoatl?

I made a picture of it and put it as my avatar

Answer 1

It is not Quetzalcoatl since that God is from Mexico and is a giant flying snake.

Your artifact seems to be a ceremonial Peruvian knife called Tumi. It was used for ritual sacrifices of Llamas for good crops, and also was used by the ancient Peruvians to perform brain surgeries (For real, ancient Peruvians made great discoveries concerning brain surgeries).

Your artifact must surely be a replica (true ones belong to museums) which are sold by merchants as souvenirs. True ones are made of gold, replicas are made of wood or cooper.

Concerning the god of the knife, it has been related commonly with Naymlap, a God king of the mythology of an ancient Peruvian culture called Lambayeque or Sican.

Glad I could help you.
