The preceding chapter was written in the summer of 1851, a year before the appearance of Stirling's "Cloister Life of Charles the Fifth," which led the way in that brilliant series of works from the pens of Amédée Pichot, Mignet, and Gachard, which has made the darkest recesses of Yuste as light as day. The publication of these works has deprived my account of whatever novelty it might have possessed, since it rests on a similar basis with theirs, namely, original documents in the Archives of Simancas. Yet the important influence which Charles exerted over the management of affairs, even in his monastic retreat, has made it impossible to dispense with the chapter. On the contrary, I have profited by these recent publications to make sundry additions, which may readily be discovered by the reader, from the references I have been careful to make to the sources whence they are derived. The public has been hitherto indebted for its knowledge of the reign of Charles the Fifth to Robertson,--a writer who, combining a truly philosophical spirit with an acute perception of character, is recommended, moreover, by a classic elegance of style which has justly given him a preëminence among the historians of the great emperor. But in his account of the latter days of Charles, Robertson mainly relies on commonplace authorities, whose information, gathered at second hand, is far from being trustworthy,--as is proved by the contradictory tenor of such authentic documents as the letters of Charles himself, with those of his own followers, and the narratives of the brotherhood of Yuste. These documents are, for the most part, to be found in the Archives of Simancas, where, in Robertson's time, they were guarded, with the vigilance of a Turkish harem, against all intrusion of native as well as foreigner. It was not until very recently, in 1844, that the more liberal disposition of the government allowed the gates to be unbarred which had been closed for centuries; and then, for the first time, the student might be seen toiling in the dusty alcoves of Simancas, and busily exploring the long-buried memorials of the past. It was at this period that my friend, Don Pascual de Gayangos, having obtained authority from the government, passed some weeks at Simancas in collecting materials, some of which have formed the groundwork of the preceding chapter.
