As a punishment from the gods for his trickery King Sisyphus was made to roll a huge boulder up a steep hill. Before he could reach the top, however, the massive stone would always roll back down, forcing him to begin again. The maddening nature of the punishment was reserved for King Sisyphus due to his hubristic belief that his cleverness surpassed that of Zeus Himself. Zeus accordingly displayed his own cleverness by consigning Sisyphus to an eternity of useless efforts and unending frustration.
