(Not that killing guests is encouraged now or anything.).

People took the laws of hospitality super seriously back then, so this was a big no-no.

Some say that he kills guests that come into his house.

There are a lot of different opinions out there about the other bad things that Sisyphus does.

Sisyphus really isn't much better than his brother though.

Sisyphus is disappointed that his plot to kill his brother doesn't work out, but in the end it doesn't matter because Zeus zaps Salmoneus with a lighting bolt for being disrespectful.

Tyro finds out what Sisyphus intends for the baby boys, though, so she kills them.

'Sounds great,' says Sisyphus, and he goes and sleeps with his niece, impregnating her with two sons.

(Psst, this is a lot like the myth of Atreus and Thyestes.).

The oracle tells him that he's got to seduce Salmoneus's daughter, Tyro, and have some kids with her.

In one well-known story, Sisyphus decides that he hates his brother, Salmoneus, and goes to an oracle to figure out the best way to kill him without getting blood on his hands.

Overall, he's known for being smart as whip, but he's also known for being a liar, a cheater, and a generally sadistic guy.

Although Sisyphus does a good job of promoting trade for his town and founds the popular Isthmian games, this dude has a really bad reputation all over the land.

Sisyphus is the founder and king of a town called Ephyra (which will one day be the big city of Corinth).

As punishment for his crimes Sisyphus must push a giant boulder up a hill for all eternity. Eventually, Zeus steps in and gets Hermes to drag Sisyphus back down to the Underworld for good. When Sisyphus is eventually put back in the Underworld, he escapes again by convincing Persephone to let him go back up and punish his wife for not giving him a proper burial (never mind the fact that he told his wife not to bury him). Sisyphus outsmarts Thanatos, though, and leaves the death god chained instead. As punishment for his crimes, Zeus sends Thanatos, the god of death, to chain Sisyphus down in Tartarus.

Some say he also kills guests and travelers, and he even betrays the secrets of the gods. He does all kinds of bad stuff like impregnate his niece in a plot to kill his brother.

Sisyphus is super smart, but super evil too. How It (Supposedly) Went Down The Short Story
