1734—Forty years of age. Voltaire had recently met the marquise du Châtelet. He was doubtless now the most conspicuous, almost the only, literary figure on the continent who wrote in the new, free spirit that began to dominate the few great minds of northern Europe. Booksellers in Europe found his writings profitable. Frederick, prince royal of Prussia, was his disciple. Two editions of his collected works had been published in Amsterdam, and he was in demand everywhere; but more trouble was brewing. J. B.
