What is "sosruko"

Sosruko or Sosriqwe is a central character in many cycles of the Nart sagas of the Caucasus.

Sosruko is a powerful but devious man who is the smallest of the Narts; as a character, he is sometimes cast in the light of the trickster god, comparable to the Scandinavian Loki (who finds a closer parallel in the Nart Syrdon however), Georgian Amirani, or the Ancient Greek Prometheus. It is possible that at least in the latter case, Sosruku served as a direct inspiration.

In Circassian mythology, it was Nart Sosriqwe, minion of the gods and his doting mother, Lady Satanaya, who stole fire from the giant.
