Apel handrail in the Naumburg Cathedral, Sysiphus

Directly on the handrail you see a man struggling with a heavy stone. Perhaps you recognize him?
It is Sysiphus who tries in vain to roll a heavy stone up to the top of the mountain. But the stone rolls back the slope every time. Here, on the railing, lies the longed-for destination just before Sysiphus: the entrance to paradise. And again there is an animal as guardian.
