When cable diving last week, I came across a "double take" image on the History Channel. The illuminated green water at a cave entrance sure looked like the Light Source cave in Lost. The narrators were describing a global network of six ancient openings or gates that old civilizations believed were passageways into the underworld or Hell. The cave image above is from a Mayan location in Belize. Once the investigative team entered the cave, they found it a dangerous place, littered with human bones. They said the Mayans used this place to go to the underworld, and to make human sacrifices to their gods. By appeasing their gods, they could sustain life on the surface world. The Light Source cave was also littered with human skulls and bones.
The concept of gates to a different dimension were part of the Lost mythology. The FDW room had hieroglyphs that made mention of Earth gates. The countdown timer in the Swan could have been used to maintain closure of a gate (a place of death). And the Light Source cave contained a hieroglyphed plug that when removed, caused the light to vanish and the island quake. That mechanism caused the "immortal" Flocke to turn into mortal form (from death, to life, to death).
