Lost has drawn on many religions and pantheons over the years. The most obvious has been Egyption with the hieroglyphs, ankh, and statue. Then there is the Hinduism suggested by Dharma. And then the Greek pantheon suggested by the Apollo bars and Cerberus notations. We have finally seen the temple and it suggests a Aztec influence on the show. While doing research on an unrelated topic I stumbled upon an Aztecs God that may be the inspiration for Nemesis. The name of this god is Tezcatlipoca.
Tezcatlipoca was the Aztecs god of the nocturnal sky and ancestral memory. He was also the god of temptation, discord, and the embodiment of change through conflict. His name means god of the smoking mirror because he carried a obsidian mirror that bellowed black smoke.
Tezcatlipoca had many names and aspects for he was a shapeshifter. As Tezcatlipoca Yaotl he was the enemy. As Tezcatlipoca Telpochtli he stands for eternal youth and when he was Necoyaotl he was the enemy of both sides.
Tezcatlipoca had two aspects that he used often. In his jaguar aspect, Tepeyollotl, he was the lord of darkened caves and echoes. In his blood stained Turkey form, Chalchihuihtotolin, he would tempt humans into self destruction. But in this form he could also cleanse humans of contamination, absolve their sins, and overcome their fates. When Tezcatlipoca carried his smoking mirror the black smoke could kill bad people or punish them with illness.
Tezcatlipoca, along with his twin brother (and also his opposite ) Quetzalcoatl, created the world. There is one myth about Quetzalcoatl that says that he allowed himself to be tempted by Tezcatlipoca but then threw himself on a funeral pyre. After that Quetzalcoatl became a symbol of death and resurrection.
There is an interesting story told by the Aztecs about Tezcatlipoca. They say that if you are alone in the woods at night and see a glowing light accompanied by a sound like chopping wood beware, for Tezcatlipoca is near. The wood chopping like sound is the sound of his ribs opening and closing. The only way to escape Tezcatlipoca is to wait for his ribs to open, thrust your hand inside and pull out his heart.
I believe that it is obvious that Tezcatlipoca parallels many of the same aspects that Nemesis/Smokey has. Considering that the writers have drawn from many areas and subjects to craft Lost I don’t think it is farfetched to think that Tezcatlipoca is the inspiration for Nemesis / Smokey. And even if Tezcatlipoca didn’t inspire them there are a lot of interesting similarities.
