Solution. Is it for the reason here rehearsed? This sort of men (as it seems) had great privileges accruing to them from the grant of King Numa, by reason of his [p. 235] godly devotion; which things afterward being taken from them when the Decemviri managed the government, they forsook the city. Whereupon there was a search made for them, and one of the priests, offering sacrifice without music, made a superstitious scruple of so doing. And when they returned not upon invitation, but led their lives in Tibur, a certain freedman told the magistrates privately that he would undertake to bring them. And providing a plentiful feast, as if he had sacrificed to the Gods, he invited the minstrels; women-kind was present also, with whom they revelled all night, sporting and dancing. There on a sudden the man began a speech, and being surprised with a fright, as if his patron had come in upon him, persuaded the pipers to ascend the caravans that were covered all over with skins, saying he would carry them back to Tibur. But this whole business was but a trepan; for he wheeling about the caravan, and they perceiving nothing by reason of wine and darkness, he very cunningly brought them all into Rome by the morning. Most of them, by reason of the night-revel and the drink that they were in, happened to be clothed in flowered women's robes; whereupon, being prevailed upon by the magistrates and reconciled, it was decreed that they should go up and down the city on that day, habited after this manner.
