Baco Verulamius alchemicis philosophis quid debuerit / Facultati Parisiensi hanc thesim proponebat Pierre Janet.
A thesis printed at Angers in 1889 by Pierre Janet, held by Glasgow University Library, on Francis Bacon's debt to alchemical philosophers, written for the Paris faculty. The single picture is a printer's emblem shield rather than a text illustration: a shield holds a bare tree, a bell, a lamp-topped pillar with an open book, and a fish, above a banner reading 'Vita veritas vita'. A designer might take its heraldic layout, banner lettering and compact symbolic motifs as a model for a crest or label.
