Not related or inspired by the more religious poetic endeavour of Milton's "Paradise Lost".
This is inspired very loosely on the destruction of the ancient civilisation known as Atlantis. Home to a nation far ahead of their time, but even with their advances the Atlanteans could not survive the wrath of nature and so the island was plunged into the deep expanse of the ocean.
I would also stress I was not influenced or inspired by that godawful BBC drama series called "Atlantis". I have not watched it and I plan never to watch it. Ever. Personally I think 'Atlantis' to be crime, not only to story-telling, but also to the virtue of the myth. From what I've heard classical Greek stories have been manipulated to fit the dynamic of a Saturday night drama serial aimed at children. Pity that children will grow up to be force fed such a load of tripe when the actual myths recorded by Homer, Hesiod, Aeschylus, Euripides and Aristophanes, etc. are a whole lot better plus they're exciting tales from our ancient past.
