The creature in Greek mythology famously known for its ability to turn living beings to stone is the Gorgon, specifically Medusa. Medusa, one of the three Gorgon sisters, was cursed by Athena and transformed into a monster with snakes for hair. Anyone who gazed directly at her would turn to stone. Medusa's story has evolved, with interpretations ranging from a fearsome monster to a tragic figure. She is often depicted in art and literature, symbolizing both danger and the complexities of feminine power.
