38. Collatia, and what land the Sabines had on the hither side of Collatia, was taken from [p. 137]them, and Egerius, the son of the king's brother, was¹ left in the town with a garrison. [2] The surrender of the Collatini took place, I understand, in accordance with this formula: the king asked, “Are you the legates and spokesmen sent by the People of Collatia to surrender yourselves and the People of Collatia?” “We are.” “Is the People of Collatia its own master?” “It is.” “Do you surrender yourselves and the People of Collatia, city, lands, water, boundary marks, shrines, utensils, all appurtenances, divine and human, into my power and that of the Roman People?” [3] “We do.” “I receive the surrender.” Upon the conclusion of the Sabine war Tarquinius returned to Rome and triumphed. [4] He then made war against the Ancient Latins. In this campaign there was no general engagement at any point, but the king led his army from one town to another until he had subdued the entire Latin race. Corniculum, Ficulea Vetus, Cameria, Crustumerium, Ameriola, Medullia, and Nomentum —these were the towns which were captured from the Ancient Latins, or from those who had gone over to the Latins. [5] Peace was then made.

From that moment the king devoted himself to peaceful undertakings with an enthusiasm which was even greater than the efforts he had expended in waging war, so that there was no more rest for the people at home than there had been in the field. [6] For he set to work to encircle the hitherto unfortified parts of the City with a stone wall, a task which had been interrupted by the Sabine war; and he drained the lowest parts of the City, about the Forum, and the other valleys between the hills, which were too flat to carry off the flood-waters easily, by means of sewers so made as to slope down toward the Tiber. [7] [p. 139]Finally, with prophetic anticipation of the splendour² which the place was one day to possess, he laid foundations for the temple of Jupiter on the Capitol, which he had vowed in the Sabine war.
