Grifone on the bridge is a Renaissance study from horatius cocles.
Such, according to old Roman story, was the feat of horatius cocles.
It was no longer a Leonidas or horatius cocles desperately holding a pass; it was an army encountering an army.
Seneca states that horatius cocles came back victorious; and Dionysius that he was wounded in the leg.
It was horatius cocles five times over, ready to defend the bridge with life.
