Sciron was an Isthmian outlaw. He dwelled at the Sceironian Rocks, a cliff on the Saronic coast of the Isthmus of Corinth. He robbed travelers passing the Sceironian Rocks and forced them to wash his feet. When they knelt before him, and were distracted by the smell, he kicked them over the cliff into the sea, where they were eaten by a monstrous sea turtle. Theseus, his half-brother through Poseidon, killed him in the same way, by pushing him off the cliff. https://riordan.fandom.com/wiki/Sciron Example shown is Berlin. Germany. Altes Museum.
