Atlantis first appeared in Plato's dialogues and was relatively unused until the past few hundred years. Atlantis was supposedly a fierce naval power who dominated the seas until one day they found themselves deep within it. The reality of the city was debated and even mocked in its time, and people took little stock in the idea of the sinking city. Then, in the 16th century, British philosopher Francis Bacon (not to be confused with the painter) re-invigorated the city as a symbol for a possible utopian society. Atlantis has been taken into the lexicon and mythology readily, inspring many people's fantasies—of being a fish-person.
