Some quote from great book.
One day Amphitryon asked his grandfather if it was true that he had turned into stone a monster that wanted to devour Grandmother Andromeda. The Aedes sang that Perseus used the head of a dead Medusa. The boy passionately wanted to hear it firsthand – it seemed to him that he would touch the feat himself.
And he heard it.
–Nonsense,– said Grandpa gloomily. – Women's gossip. What kind of head? I slaughtered him like a butcher slaughtering a pig. I flew higher, waited until the stupid animal was interested in my shadow on the waves, and fell on the back of his neck… Then everything was simple. A lot of blood, and the end. They'll come up with it too: A Medusa, a head! I guess there won't be anything left of my whole life over time. Medusa, a bunch of rocks, and no Perseus…

I hope one day I put more bit from this book. Old Perseus is damn badass (and scary, if he want).
