Zeus was so taken with Leda's beauty that he turned himself into a swan to seduce her. From their union came Helen, Clytemnestra, Pollux & Castor. Helen, of course, was so beautiful that after she ran off with Paris to Troy, Menelaus and his brother Agamemnon got the Greeks together to cross the Aegean to storm Troy. It's easy to see why, if her mother looked like this.
In the modern world, I was so taken with Leda's beauty that I approached at an event at the ambassador's residence, and asked if she'd be a model for my Faces of Aphrodite project. She agreed, though it took 6 months and two intercontinental flights to make it happen. But I'm very happy with the results.
