Explanation: Sisyphus was a being of Greek mythology who was punished for defying the gods by being forced to roll a boulder up a hill, only for it to roll back down. And then having to roll it back up. Repeat ad infinitem. For eternity. For this reason, repetitive and futile tasks are often known as ‘Sisyphean’.

Here, our modern Sisyphus is bringing the same rock, every night, for eternity. The toil truly never ends
