Other singers of this period were Lavinia Fenton, who became the Duchess of Bolton, and who is chiefly remarkable for having been the original Polly in Gay's "Beggar's Opera;" Marthe le Rochois, who sang many of Lulli's operas,--a woman of ordinary appearance but wonderful magnetism; Madame La Maupin, one of the wildest, most adventurous and reckless women ever on the stage; and Caterina Mingotti, a faultless singer, of respectable habits. Mingotti was seized with the fatal ambition to manage opera, and soon reached the verge of bankruptcy. She contrived, however, to earn enough by singing during the succeeding five years to support her respectably in her old age. To this period also belongs Farinelli, or Broschi, who was the greatest tenor of his age, perhaps the greatest who ever lived, for we are told that there was no branch of his art which he did not carry to the highest pitch of perfection. His career of three years in London was a continuous triumph, and he is said to have made L5,000 each year,--a very large sum in those days. His singing also restored to health Philip V. of Spain, who was a prey to depression, and neglected all the affairs of his kingdom. At the court of Spain his influence became immense until Charles III. ascended the throne, when Farinelli quitted Spain, "at the royal suggestion," and retired to Bologna. Of the long list of men who have distinguished themselves as singers in opera, it is curious to note that almost, if not quite, the first were a Mario and a Nicolini, names which are familiar to us as belonging to well-known tenors of this (nineteenth) century. Of Mario but little is recorded; but Nicolini, whose full name was Nicolino Grimaldi Nicolini, and who was born in 1673, is known to have sung at Rome in 1694. He remained on the stage until 1726, but the date of his death is unknown. Nicolini sang in England in 1708, and at several subsequent times, and was well received. Addison wrote of him, concerning his acting, that "he gave new majesty to kings, resolution to heroes, and softness to lovers."
