Artists love to mix their real life and their art. And sometimes, it's hard to tell the difference between what's real and what's not. Think about it. Miley Cyrus is a pop singer, but she also played one on Hannah Montana. Where did the character stop and the real person begin? The mind boggles.
In the Pygmalion myth, the boundary between art and life gets very blurry. Pygmalion makes a statue so lifelikethat he starts treating it like an actual person. Even as he's touching it (and, um, it's made of ivory), he keeps thinking it might be real. Seriously, every time he kisses the statue's lips, he's like, "Maybe they'll be soft this time!" (Nope. Still rock-hard.)
When the statue finally does come to life, the division between art and life completely falls away—now she's actually a real person. Art is life! Life is art! It's all mixed up.
