Serendipity created a topic of The Hounds of Sisyphus

Sisyphus: a mythology character that was punished for his bad behaviour with pushing a rock up a mountain knowing at the end of the day it would fall down and his efforts were in vain, next day he would have start all over again being forced to repeat this repetitive circle everyday. I have no idea about the concept of "hounds" of Sisyphus but I'm curious to know why the use of his name on the title.
