The palace they call Knossos in Crete has to be the source for all the labyrinth-minotaur stuff, yes. Dozens of squirreled-away rooms upon rooms. But to a tourist circa 2008 there is so so little to trust. Conjectured stairways made of obvious 1903 concrete. Restored columns a little too perfect red. And this:

Not a Minoan fresco, or a restored Minoan fresco. But a copy of a restored Minoan fresco. The original (by Emile Gillieron, assistant to Arthur Evans, the guy who excavated it) is in the museum at Iraklio. You can see where the real pieces end and interpolations begin, at least. And they left the bottom corner to our imaginations. But what true details there remain need every exegesis!
Bare-chested women? Priestesses? Goddesses? An actual matriarchy here.

Crowds of anonymous men. Red-faced as always.

And crowds within crowds. Are they all watching a ceremony, a dance?

What are those things sticking up at the top? Legs, arms? Why? And what's happening with the blue on the bottom out of nowhere like that, with the man's arm extending into it?
A better question: why isn't this one on postcards instead of that ridiculous Prince of the Lillies?
