The French, though not an insular people, have been subject to rapid revolutions in their language. The ancient Gaulish-French has long been as unintelligible to a modern Frenchman as our Saxon is to us; even those numerous poets of France who at a later period composed in their _langue Romane_, are strewed in the fields of their poesy only as carcasses, which no miracle of antiquarian lore shall ever resuscitate. Compare the style of one writer with another only two centuries later, or Rabelais with Voltaire! The age of Louis XIV. effected the most rapid change in the vernacular style, insomuch that the diction of the writers of the preceding reign of Louis XIII. had fallen obsolete in the short space of half a century. And yet the chastened style of the age of Louis XIV., with its cold imitation of classical antiquity, was to receive a higher polish from the hand of a Pascal, a novel brilliancy from the touch of a Montesquieu, and a more numerous prose from the impassioned Rousseau. The age of erudition and taste was to be succeeded by the more energetic age of genius and philosophy. An anecdote recorded of Vaugelas may possibly be true, and is a remarkable evidence of this perpetual mobility of style. This writer lived between 1585 and 1650, and during thirty years had been occupied, _more suo_, on a translation of Quintus Curtius. It was during this protracted period that the French style was passing through its rapid transitions. So many phrases had fallen superannuated, that this martyr to the purity of his diction was compelled to re-write the former part of his version to modernise it with his later improved composition. The learned Menage lived to be old enough to have caught alarm at this vicissitude of taste, and did not scruple to avow that no work could last which was not composed in Latin.
