Here's a trope in art that never gets old - The Idealized Woman. She's the virgin/mother/princess/bride. Every little thing she does is magic, everything she touches becomes Life. She is the star that never dies, She is the sea that never ends... and She's not real. But that's okay.
She reminds a bit of that mythic Ireland that Butler Yeats speaks of. The kind of place that is too magical to be real, but it still inspired by the real Ireland. In the same way, the Idealized Woman of countless poems is too perfect to be real, but she is inspired by the women of our life. The good ones.
