USER: Write a concise summary of the following. Be sure to preserve important details: Once upon a time, Corinth was a very strong Greek city-state, the remains of which can be found to this day. Some sources refer to the great city of Efyra as the city founded by Sisyphus, which was later named Corinth. Others say that the witch Medea gave Corinth to Sisyphus, who became its king. One day, Asopos' daughter, Aegina, had been abducted by Zeus and when Asopos asked if Sisyphus had seen anything, Sisyphus mentioned that he saw Zeus fly over with Aegina. When Zeus heard that, he got really angry that he was betrayed by a mortal. So, the king of the gods sent Death to take Sisyphus' life. However, when Death came to chain Sisyphus, the latter asked Death a demonstration of how the chains work and then deceived Death and chained him instead.
