A little before the city of Dyme there is, on the right of the road, the grave of Sostratus. He was a native youth, loved they say by Heracles, who outliving Sostratus made him his tomb and gave him some hair from his head as a primal offering. Even today there is a slab on the top of the mound, with a figure of Heracles in relief. I was told that the natives also sacrifice to Sostratus as to a hero.
