He refused to acquit his young man, but submitted to the loss of one of his own eyes instead of exacting the full penalty of the offender; He also established a law forbidding a citizen to enter the Senate-house bearing a weapon but he violated his law in a sudden emergency during the stress of war, was reminded of the law, and straightway fell upon his sword as a sacrifice to the sovereignty of the claims of social order.
