Clermont-Ferrand - Notre-Dame-Du-Port

The capitals in the Basilica Notre-Dame-Du-Port are very elaborate. On some of them even a signature (ROTBERTUS) could be found.

This capital, perfectly carved, differs thematically.
It depicts an ape - on a rope, led a man. I have seen a couple of carved monkeys and apes before, but never such a giant creature with such a threatening facial expression. This ape is at least as tall as the man on the side, probably taller, as the ape is bending his knees The ape seen here is probably a symbol for the evil, a creature from hell, - but the evil here is under control of the man.
