Symbol of Corosh'nai

From The Stargate Omnipedia


A dark and imposing statue representing a warning to "turn back." It is used as a warning to Goa'uld and Jaffa, typically posted near the Stargate, to advise travelers that the world has been left in waste by Goa'uld invaders, and is possibly still radioactive.
