In the course of the year 1653 Sir Thomas Urquhart published the last of his original works--his _Logopandecteision_, and the translation of the first two books of Rabelais, in connection with which his name is best known. The object of the former of these was to suggest a wonderful scheme for a universal language, with the idea of being restored by the Government to the full possession of his liberty, and of being reinstated in the position of power and wealth, which he maintained was his by hereditary right, in order to carry out the scheme. His hopes and anticipations of success in this appeal to the English Government were not daunted by the fact that to do what he required would need several legislative changes, a reversal of proceedings in Scottish courts of law, and a substantial grant from the Treasury. This, after all, he considered, was a very small price to pay for the benefits he would thereby confer upon the world. That the appeal was not successful needs scarcely be told. Probably in no country in the world, and at no period in history, could any be found more likely to turn a deaf ear to such requests, than such men as Cromwell, Fleetwood, and Overton. Men like these were too practical, and of too hard a nature, to be impressed by any such visionary schemes as those which their prisoner delighted in constructing. A veil of obscurity hangs over the closing years of our author's life. His last appearance before the public was in the issuing of the books above mentioned. The only further record of him is in the continuation of the Pedigree of the Urquharts, which is contained in the Edinburgh edition of his Tracts. In this we read that "he was confined for several years in the Tower of London; from whence he made his escape, and went beyond seas, where he died suddenly in a fit of excessive laughter, on being informed by his servant that the King was restored."[126] If this account of matters be true, it would seem that Sir Thomas had forfeited some of those privileges which he had won so soon after he had become a State prisoner. It is quite possible that this was in consequence of having joined in some Royalist plot against the Commonwealth and for the restoration of Charles II. In the preface to the second book of Rabelais, Sir Thomas promises very speedily to translate the three remaining books of that author, so that the whole "Pentateuch of Rabelais," as he calls it, might be in the hands of English readers. But this design was never completed. The translation of the third book was found among his papers, and was published in 1693 by Pierre Antoine Motteux, but it is probable that the editor himself had some share in the work as issued to the public.
