The Fall of Lucifer and the Rebel Angels, illustration from a copy of the 'Biblia...

The Biblia pauperum ("Paupers' Bible") was a tradition of picture Bibles beginning probably with Ansgar, and a common printed block-book in the later Middle Ages to visualize the typological correspondences between the Old and New Testaments. Unlike a simple "illustrated Bible", where the pictures are subordinated to the text, these Bibles placed the illustration in the centre, with only a brief text or sometimes no text at all. Words spoken by the figures in the miniatures could be written on scrolls coming out of their mouths. To this extent one might see parallels with modern cartoon strips.
