Meursault vs. Camus' Sisyphus

When I was reading Camus' analysis of Sisyphus' struggle, I couldn't help but think about how similar Sisyphus seemed to Meursault.

• Sisyphus' crimes and mischief during his life = Meursault murdering the Arab
• Sisyphus' underworld = Meursault's jail cell
• Sisyphus' unending rock-moving task = Meursault's repetitive prison schedule
• Sisyphus' hour of consciousness = Meursault's moments of deep thought/room exploration

Of course, the parallels aren't perfect. Sisyphus is damned to eternity pushing a rock up a mountain, and Meursault is only in jail for a year. Meursault is able to speak with guards, go for walks, and eat meals, whereas Sisyphus just spends all of his time pushing a rock up a mountain and then walking down to retrieve it when it falls. Still, it's obvious that Camus' belief that people can get through anything shines through in both The Stranger and "The Myth of Sisyphus." I wonder which he wrote first, and if one could have influenced the other.
