The perfect man/ woman. Like the mythical city, he/she may or may not exist. This person possesses all of the positive attributes one could possibly desire.
I've found Atlantis. He's the most amazing man I've ever met.

Mythical place, told of by Socrates (i think), where all people work together in harmony. It was this ideology of a pure race and a pure place that led to the Holocaust in the Second World War.

Also, the name given to an ancient Greek city, well known for its good work ethics, which was hit by a tidal wave a couple of thousand years ago.

These two stories are usually linked, and it is not known if Socrates meant that Atlantis was a real place or a spiritual ideal.
Well if it does exist, there is one example. If it doesnt, there is none.
