Some of Kythera is fashioned of rock that began as small creatures - coiling, multi-chambered shells, which descended infinitely - gently - in death to the sea floor. Here water pressure cemented and crystalized them over many millions of years. Movements which occurred in the very crust of the earth, deeper than the ocean itself, conspired to return them to the surface to become the limestone foundations - the bedrock - of continents and islands.
