Interpretations
According to the solar theory, King Sisyphus is the disk of the sun that rises every day in the east and then sinks into the west. Other scholars regard him as a personification of waves rising and falling, or of the treacherous sea. The 1st-century BC Epicurean philosopher Lucretius interprets the myth of Sisyphus as personifying politicians aspiring for political office who are constantly defeated, with the quest for power, in itself an "empty thing", being likened to rolling the boulder up the hill. Friedrich Welcker suggested that he symbolises the vain struggle of man in the pursuit of knowledge, and Salomon Reinach that his punishment is based on a picture in which Sisyphus was represented rolling a huge stone Acrocorinthus, symbolic of the labour and skill involved in the building of the Sisypheum. Albert Camus, in his 1942 essay The Myth of Sisyphus, saw Sisyphus as personifying the absurdity of human life, but Camus concludes "one must imagine Sisyphus happy" as "The struggle itself towards the heights is enough to fill a man's heart."
In experiments that test how workers respond when the meaning of their task is diminished, the test condition is referred to as the Sisyphusian condition. The two main conclusions of the experiment are that people work harder when their work seems more meaningful, and that people underestimate the relationship between meaning and motivation.
