In Greek mythology, Sisyphus or Sisyphos was the founder and king of Ephyra. He was a devious tyrant who killed visitors to show off his power. This violation of the sacred hospitality tradition greatly angered the gods. They punished him for trickery of others, including his cheating death twice. The gods forced him to roll an immense boulder up a hill only for it to roll back down every time it neared the top, repeating this action for eternity. Through the classical influence on modern culture, tasks that are both laborious and futile are therefore described as Sisyphean.

Corinth was a city-state (polis) on the Isthmus of Corinth, the narrow stretch of land that joins the Peloponnese to the mainland of Greece, roughly halfway between Athens and Sparta. The modern city of Corinth is located approximately 5 kilometres (3.1 mi) northeast of the ancient ruins. Since 1896, systematic archaeological investigations of the Corinth Excavations by the American School of Classical Studies at Athens have revealed large parts of the ancient city, and recent excavations conducted by the Greek Ministry of Culture have brought to light important new facets of antiquity.
