The Senate immediately appointed Cincinnatus, a noble patrician, dictator. The ambassadors that carried to him the message from the Senate found him upon his little farm near the Tiber, at work behind the plough. Accepting the office at once, he hastily gathered an army, marched to the relief of the consul, captured the entire army of the Æquians, and sent them beneath the yoke. [Footnote: This was formed of two spears thrust firmly into the ground and crossed a few feet from the earth by a third. Prisoners of war were forced to pass beneath this yoke as a symbol of submission.] Cincinnatus then led his army back to Rome in triumph, laid down his office, and sought again the retirement of his farm. THE DECEMVIRS AND THE TABLES OF LAWS.--Written laws are always a great safeguard against oppression. Until what shall constitute a crime and what shall be its penalty are clearly written down and well known and understood by all, judges may render unfair decisions, or inflict unjust punishment, and yet run little risk--unless they go altogether too far--of being called to an account; for no one but themselves knows what the law or the penalty really is. Hence in all struggles of the people against the tyranny of the ruling class, the demand for written laws is one of the first measures taken by the people for the protection of their persons and property. Thus we have seen the people of Athens, early in their struggle with the nobles, demanding and obtaining a code of written laws (see p. 119). The same thing now took place at Rome. The plebeians demanded that a code of laws be drawn up, in accordance with which the consuls, who exercised judicial powers, should render their decisions. The patricians offered a stubborn resistance to their wishes, but finally were forced to yield to the popular clamor. A commission was sent to the Greek cities of Southern Italy and to Athens to study the Grecian laws and customs. Upon the return of this embassy, a commission of ten magistrates, who were known as decemvirs, was appointed to frame a code of laws (451 B.C.). These officers, while engaged in this work, were also to administer the entire government, and so were invested with the supreme power of the state. The patricians gave up their consuls and the plebeians their tribunes. At the end of the first year, the task of the board was quite far from being finished, so a new decemvirate was elected to complete the work. Appius Claudius was the only member of the old board that was returned to the new.
