21. For¹ the next three years there was neither settled peace nor open war. The consuls were Q. Cloelius and T. Larcius. They were succeeded by A. Sempronius and M. Minucius. [2] During their consulship a temple was dedicated to Saturn and the festival of the Saturnalia instituted. The next consuls were A. Postumius and T. Verginius. [3] I find in some authors this year given as the date of the battle at Lake Regillus, and that A. Postumius laid down his consulship because the fidelity of his colleague was suspected, on which a Dictator was appointed. [4] So many errors as to dates occur, owing to the order in which the consuls succeeded being variously given, that the remoteness in time of both the events and the authorities make it impossible to determine either which consuls succeeded which, or in what year any particular event occurred.

[5] Ap. Claudius and P. Servilius were the next consuls. This year is memorable for the news of Tarquin's death. His death took place at Cuma, whither he had retired, to seek the protection of the tyrant Aristodemus after the power of the Latins was broken. [6] The news was received with delight by both senate and plebs. But the elation of the patricians was carried to excess. Up to that time they had treated the commons with the utmost deference, now their leaders began to practise injustice upon them.

[7] The same year a fresh batch of colonists was sent to complete the number at Signia, a colony founded by King Tarquin. The number of tribes at Rome was increased to twenty-one. The temple of Mercury was dedicated on May 15.
