After the animals overthrow Mr. Jones, they discover that life on Animal Farm is not as easy and carefree as they thought it would be. Although the farm has plentiful resources, the animals lack the ability to use tools designed for humans. As a result, they must invent new ways to provide for themselves, which often requires work that is strenuous, exhausting, and unsuccessful. The animals’ hapless attempts to break up rocks in the quarry closely resemble the Greek myth of Sisyphus, who was cursed to eternally roll a boulder up a hill, only to have it roll back down when he reached the top.
