He referred to a period "inter prima artis [typographicae] incunabula" ("in the first infancy of the typographic art").[10][11] The term has sometimes been falsely attributed to Bernhard von Mallinckrodt (1591–1664), in his Latin pamphlet De ortu ac progressu artis typographicae ("On the rise and progress of the typographic art"; 1640), but he was simply quoting Junius.[12][13]
