We have come to an epoch when the difficulties resulting from confusion between the booksellers' and binders' trades began to be understood. The revocation of the Edict of Nantes had implicitly prepared a crowd of measures and rules in all branches of national industry. It was a good occasion to prevent the artisans of binding unduly parading themselves as booksellers and selling merchandise of which they understood nothing; Louis XIV. interfered, and separated the two communities. The binders then became the _relieurs-doreurs_ of books; they had their own organisation, but remained subject to the university; the heads of the fraternity were called the "guards." The principal arrangements of the regulation of 1749 were: the members of the corporation had the sole right to bind books, from the elegant volume to registers of blank paper. Five years of apprenticeship and three of companionship were necessary to obtain the brevet of freedom and to hold a shop. Moreover, it was indispensable to read and write. One regulation ordained that the workman should be "able to bind and ornament ordinary books or others, to render them perfect and entire, to sew the sheets at most two together with thread and real bands, with joints of parchment, and not paper, and in case of infraction the said books were to be remade at the expense of the offender, who was besides condemned to a penalty of thirty livres for each volume." Their establishment was confined to the quarter from the Rue St. André des Arts to the Place Maubert; they regulated the sale of calfskin and of tools; in a word, they were surrounded by precautions by which the production remained always under the supervision of the masters and completely satisfied the client. This calculating policy was, in fact, a close imitation of the royal ordinance of 1686. [Illustration: Fig. 117.--Mosaic binding of the eighteenth century for the _Spaccio de la Bestia Trionfante_.]
