In the first place, then, as regards cast of features and look and bearing, Tiberius was gentle and sedate, while Caius was high-strung and vehement, so that even when haranguing the people the one stood composedly in one spot, while the other was the first Roman to walk about upon the rostra and pull his toga off his shoulder as he spoke. So Cleon the Athenian is said to have been the first of the popular orators to strip away his mantle and smite his thigh.[*](See the Nicias, viii. 3. )
