If you're an accomplished or budding artist you may enjoy these lovely sketches from Roman mythology. I especially like the one depicting Narcissus and will be using it for inspiration sometime soon.
I've always liked the Amphion and Zethus pic, they've always reminded me of Apollo (Zethus) and Hermes (Amphion) - which is sad because Amphion's sons and daughters die by Leto's twins Artemis and Apollo.
