Besides monarchs, the princes, noblemen and simple middle class of all conditions seemed to be collectors at this period. The passion for collecting numbers names such as Richelieu and Mazarin, among antiquaries, amateurs and dealers were Jabach and others. The number and importance of art collections, as well as of intelligent art lovers in France during the seventeenth century, can be gathered from the many publications on this century. They are many, and most of the contemporary ones are quite documentary and important for the number of collectors they mention. We may quote among them the _Itinerarium Galliæ_, 1612, by Just Zinzerling, a German signing himself Jodocus Sincerus, Abraham Golnitz’s _Ulysses Belgico-Gallico_, a work written in 1631 dealing with the collections of medals and painting that the author found in France during his journey. There is also the _Voyage pour l’instruction et la commodité tant des François que des Étrangers_, printed in 1639 and reprinted by Verdier, with interesting additions, in the year 1687. John Evelyn, the English diarist, visited France in the year 1643 and gave an account of many collections of art and their cabinets, which was partially republished in the _Voyage de Lister_, in an edition of the year 1878. We can enumerate further the _Traité des plus belles bibliothèques_, published for the first time in 1644 by Père Louis-Jacob, the librarian of Cardinal de Retz and of President Du Harlay; the _Liste anonyme des curieux des diverses villes_, etc. In these works thousands of names of collectors of art, whether specialists or not, are mentioned, not only those residing in Paris but in all towns of the provinces. Collectomania was becoming epidemic!
