In 1364, the royal library of France did not exceed twenty volumes. Shortly after, Charles V. increased it to 900, which, by the fate of war, as much at least as by that of money, the Duke of Bedford afterwards purchased and transported to London, where libraries were smaller than on the continent, about 1440. It is a circumstance worthy observation, that the French sovereign, Charles V. surnamed the Wise, ordered that thirty portable lights, with a silver lamp suspended from the centre, should be illuminated at night, that students might not find their pursuits interrupted at any hour. Many among us, at this moment, whose professional avocations admit not of morning studies, find that the resources of a public library are not accessible to them, from the omission of the regulation of the zealous Charles V. of France. An objection to night-studies in public libraries is the danger of fire, and in our own British Museum not a light is permitted to be carried about on any pretence whatever. The history of the "Bibliothèque du Roi" is a curious incident in literature; and the progress of the human mind and public opinion might be traced by its gradual accessions, noting the changeable qualities of its literary stores chiefly from theology, law, and medicine, to philosophy and elegant literature. It was first under Louis XIV. that the productions of the art of engraving were there collected and arranged; the great minister Colbert purchased the extensive collections of the Abbé de Marolles, who may be ranked among the fathers of our print-collectors. Two hundred and sixty-four ample portfolios laid the foundations, and the very catalogues of his collections, printed by Marolles himself, are rare and high-priced. Our own national print gallery is growing from its infant establishment. Mr. Hallam has observed, that in 1440, England had made comparatively but little progress in learning--and Germany was probably still less advanced. However, in Germany, Trithemius, the celebrated abbot of Spanheim, who died in 1516, had amassed about two thousand manuscripts; a literary treasure which excited such general attention, that princes and eminent men travelled to visit Trithemius and his library. About this time, six or eight hundred volumes formed a royal collection, and their cost could only be furnished by a prince. This was indeed a great advancement in libraries, for at the beginning of the fourteenth century the library of Louis IX. contained only four classical authors; and that of Oxford, in 1300, consisted of "a few tracts kept in chests."
