That clod Polyphemus, who you may know as Cyclops, kept after her, singing his mangled songs and giving her cheap, gaudy gifts. Not how you woo a sea nymph, I'll tell you that. So Galatea took up with the pool boy, Acis. When word got back to Ol' One Eye, he threw a fit and crushed the kid's skull with a boulder. He could do that, you know, since he was a giant. Well, the rock split open and water spilled out and the water was Acis. He flowed all about and eventually made it to her sea.
