Pygmalion is the story of a
sculptor who was so incredibly skilled in his art that he fell in love with one of his statues, and when he slept with it, it
came to life.
It is one of a bundle of Greek myths about metamorphosis, left to us in the words of Ovid. As far as I'm aware, they are mainly concerned with the consequences of sexual desire.
For a modern, Americanized version, see the Stepford wives.
'Pygmalion' is also a play by George Bernard Shaw, with a very different message, as far as I can see.
