One of 2 cornice details showing pairs of Telamons. (thanks Lapin)
The name Telamon derives from a Greek word meaning support or bearer. Telamon is thus shown in sculpture as a brawny male bearing a weight or burden. His name has become the architectural term for a sculpted figure with arms aloft holding a cornice or a lintel. - See more at: http://blog.classicist.org/?p=2977
