Blockbooks were used for popular religious literature because of the close relationship they set up between images and explanatory texts, both cut and printed from the same wooden block. In the Apocalypse blockbook there is an abbreviated form of the Biblical text in Latin, along with excerpts from the 9th-centruy gloss of Berengaudus, incorporated into the woodcut image. This image is then coloured with water-based ink, frequently using orange, yellow, russet, green, brown, black, and grey.
This extremely rare leaf is from one of 6 total editions by Schreiber, a reminder of this 'archaic' technique that was used by printers before and contemporaneously with Gutenberg's invention of moveable, type c. 1455. The dating and localisation of blockbooks is generally difficult due to the ubiquity of their creation, and the survival of this leaf is surprising because of how many were circulated in the 15th-century. Most did not endure due to intensive use over a long period.
