Chelone was a woman who lived in a house by a river. She was the only human to refuse Hermes' invitation to the great wedding of Zeus and Hera. For this she was punished by the gods, who had Hermes topple her into the river. Her house fell into the river as well, on top of her, and ever since then she was cursed to carry her house on her back and forever be silent.
Cheilona means tortoise in Greek.
