were very stringent. He imposed a heavy tax upon dress and personal adornment, especially of women, and upon young slaves purchased as favourites. In 181 BC he supported the lex Orchia (according to others, he first opposed its introduction, and subsequently its repeal), which prescribed a limit to the number of guests at an entertainment, and in 169 BC the lex Voconia, one of the provisions of which was intended to limit the accumulation of what Cato considered an undue amount of wealth in the hands of women. Public works Among other things he repaired the aqueducts, cleansed the sewers, and prevented private persons drawing off public water for their own use. The Aqua Appia was the first aqueduct of Rome. It was constructed in 312 BC by Appius Claudius Caecus, the same Roman censor who also built the important Via Appia. Unauthorised plumbing into Rome's aqueducts had always been a problem, as Frontinus records much later. Cato also ordered the demolition of houses which encroached on the public way, and built the first basilica in the Forum near the Curia (Livy, History, 39.44; Plutarch, Marcus Cato, 19). He raised the amount paid by the publicani for the right to collect taxes and, at the same time, reduced the contract prices for the construction of public works. Later years From the date of his censorship (184) to his death in 149, Cato held no public office, but continued to distinguish himself in the Senate as the persistent opponent of the new ideas. He was struck with horror, along with many other Romans, at the licence of the Bacchanalian mysteries, which he attributed to the influence of Greek manners, and he vehemently urged the dismissal of the philosophers Carneades, Diogenes, and Critolaus, who had come as ambassadors from Athens, on account of what he believed was the dangerous nature of their ideas. He also uttered warnings against the influence of Chaldean astrologers who had entered Italy along with Greek culture. He had a horror of physicians, who were chiefly Greeks. He obtained the release of Polybius, the historian, and his fellow prisoners, contemptuously asking whether the Senate had nothing more important to do than discuss whether a few Greeks should die at Rome or in their own land. It was not until his eightieth year that he made his first acquaintance with Greek literature, though some think after examining his writings
