As I've written in other blog posts, the fact that Tunisia is on the opposite side of the world from the South Pacific and the presumable location of the Island is likely significant. Furthermore, Tunisia's proximity to Egypt is interesting given the proliferation of hieroglyphs we've seen around the Island, notably by the frozen wheel, the Temple, in the Swan, and on the control room door for the Monster. I've theorized in the past that the ancients who first settled the Island and we responsible for building things like the Ruins and the four-toed statue had some connection to Egypt. Perhaps they were a community of people living in what is modern day Tunisia who had fled Egypt, were Egyptian themselves, or at the very least were familiar with Egyptian culture.
Hurley's painting of the Sphinx adds to this Egyptian connection.
Any thoughts on this?
