What a strange thing is a man beneath the waves. What a weird, dangerous journey to undertake, to venture into a place where you cannot breathe; to mix, without defences, with things that might tear you apart; to float in an alien element over the ruins of a temple empty these thousand years. All done in quest of what, exactly? Not power, not wealth. He possesses both. Wonder? Is there not enough that is beautiful and appalling on dry land?
