Note 137 — XIV

The Latin and Dutch editions of the Speculum maintain such a remarkable conformity with each other in the engravings, in the types, in the quality of the paper, in the presswork, and in every typographic feature, that it is evident that the four editions were published in the same country and by the same printer. As all bibliographers, whatever theory they may have concerning the origin of printing, attribute, without hesitation, the Dutch edition of the Speculum to Holland, the Latin editions should also be attributed to Holland. Guichard, Notice sur le Speculum, pp. 118 and 119. This is the opinion of all bibliographers except Heineken.
