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.
All the senators, of course, were greatly disturbed, and Nasica demanded that the consul should come to the rescue of the state and put down the tyrant. The consul replied with mildness that he would resort to no violence and would put no citizen to death without a trial; if, however, the people, under persuasion or compulsion from Tiberius, should vote anything that was unlawful, he would not regard this vote as binding. Thereupon Nasica sprang to his feet and said: Since, then, the chief magistrate be trays the state, do ye who wish to succour the laws follow me.
With these words he covered his head with the skirt of his toga and set out for the Capitol. All the senators who followed him wrapped their togas about their left arms and pushed aside those who stood in their path, no man opposing them, in view of their dignity, but all taking to flight and trampling upon one another.
