Levet, along with many dull books issued some very interesting ones. Towards the end of the century an enterprising publisher, Antoine Verard, kept many of the Paris printers busy, and Paris became noted typographically for its fine illustrated editions of the Hours of the Blessed Virgin, issued by Verard, Dupre, Pigouchet (and his publisher, Simon Vostre), and Thielman Kerver. But these with the publications of Verard belong to another chapter. At Lyon printing was introduced by the enterprise of one of its citizens, Barthelemi Buyer, who engaged Guillaume Leroy (a native of Liege) to print for him, and subsequently employed other printers as well. The first Lyon book was a little volume of popular religious treatises, containing among other things the _De miseria humanae conditionis_ of Pope Innocent III. It was completed 17 September, 1473. Until nearly 1490 the books printed at Lyon were mainly popular in character with a considerable proportion of French books, many of them illustrated. From 1490 onwards learned Latin books occur more frequently, and printing rapidly became as general or miscellaneous as at Paris itself, although only a single attempt was made, unsuccessfully, to rival the Paris _Horae_. The two cities between them probably produced more than three-fourths of the three thousand incunabula, which at a rough guess may be attributed to French presses, the share of Paris being about twice as great as that of Lyon. According to the stereotyped phrase, printing was introduced into no fewer than thirty-seven other French towns during the fifteenth century, but as a rule the printers were but birds of passage, and it was only at Poitiers (1479) and Rouen (1487) that it took root and flourished continuously, though on but a small scale. In other towns the struggle to maintain a press continued for several years, as at Toulouse, or was abandoned after the fulfilment of a single commission.
