BMC IX, 42: IB.47507) -- Wavre (Brabant), Reformed Franciscans (1705 inscriptions in Latin, French and Dutch) -- Eric Sexton (bookplates, sale Christie's, New York, 8 April 1981, lot 5).
First and only 15th-century edition from the Low Countries of an authoritative compendium of canon law by the Franciscan Angelo Carletti, first printed in his native town of Chivasso in 1486. Thierry Martens and Johannes de Westfalia, the two prototypographers of the southern Low Countries, almost certainly spent time in Italy before setting up the first Belgian press at Alost in 1473. Westfalia was evidently the senior partner and a more experienced typographer; he may have worked at Venice before the crisis of 1473, and he seems to have owned the press and the distinctly Italianate type material. When Johannes left to study law at Louvain, Martens continued alone for a few months, then abruptly disappeared for 12 years, possibly to Spain (cf. Hellinga, Printing Types I, p. 78). During this period Martens undoubtedly returned to Italy, for when he set up his second Alost press in 1486, his two principal typefaces, both used here, were modelled after types of Ratdolt, from whom they may have been acquired. Martens' humanist inclinations and Italian orientation are also evident from the texts he chose to publish, both at this first press and later at Antwerp and Louvain, and from his continued use of Venetian-style gothic types, even after Netherlandish types had come into vogue, and until he definitively turned to roman types in 1501.
