Tiberius and Caius Gracchus

Tiberius, accordingly, reported this to those who stood about him, and they at once girded up their togas, and breaking in pieces the spear-shafts with which the officers keep back the crowd, distributed the fragments among themselves, that they might defend themselves against their assailants. Those who were farther off, however, wondered at what was going on and asked what it meant.

Whereupon Tiberius put his hand to his head, making this visible sign that his life was in danger, since the questioners could not hear his voice. But his opponents, on seeing this, ran to the senate and told that body that Tiberius was asking for a crown; and that his putting his hand to his head was a sign having that meaning.
