Having fought and conquered the Sabines, he took from them Collatræ, as a collateral security for their good behaviour; and coming home with a great deal of money, he built the Temple of Jupiter on the capitol.
Tarquinius, being desirous of increasing the army, was opposed by a celebrated augur of the day, one Attus Navius, whose reputation seems to have been well deserved, if the annexed anecdote is to be believed; for it indicates that he could see further into a whetstone than any one who has either gone before or followed him. Navius declared that augury must determine whether the plan of Tarquinius could be carried out, which caused the latter to ask, sneeringly, whether he knew what he was thinking about. The question was ambiguous, but Navius boldly replied he did, and added, that what Tarquinius proposed to do was perfectly possible. "Is it indeed," said the King, "I was thinking of cutting through this whetstone with this razor." "It will be a close shave," was the reply of the augur, "but it can be done, so cut away;" and the bluntness of the observation was only equalled by the sharpness of the blade, which cut the article in two as easily as if it had been a pound of butter, instead of a stone of granite. This reproof was literally more cutting than any other that could have been possibly conveyed to the king, who ever afterwards paid the utmost respect to the augurs, of whom he was accustomed thenceforth to say, that the affair of the whetstone proved them to be much sharper blades than he had been willing to take them for.
Having been at war with the Tuscans, whom he vanquished, he was admitted into the ranks of the Kings of Etruria; a position which led him to indulge in the most extravagant desires. He must needs have a crown of gold, which often tears or encumbers the brow it adorns; a throne of ivory, on whose too highly polished surface the foot is apt to slip; and a sceptre, having on its top an eagle, which frequently gives wings to the power it is intended to typify. His robe was of purple, with so costly an edging, that the border exceeded all reasonable limits, and furnished an instance of extravagance carried to the extreme, while the rate at which he went on may be judged from the fact of his always driving four in hand in his chariot. He did not, however, wholly neglect the useful in his taste for the ornamental; and though his extravagance must have been a drain upon the public pocket, he devoted himself to the more honourable drainage of the lower portions of the city. He set an example to all future commissioners of sewers, by his great work of the _Cloaca Maxima_, some portion of which still exists, and which contains, in its spacious vault, a far more honourable monument than the most magnificent tomb that could have been raised to his memory.
