Incipit prologus formicarij iuxta edic[i]onem fratris Ioh[ann]is Nyder ..
A late fifteenth-century Latin treatise, the Formicarius of Johannes Nider, printed in Cologne by Ulrich Zell and held by the Boston Public Library, aimed at clerics and scholars writing on theology and witchcraft. The two pictures are a Boston Public Library seal with a wreath, figures and a central shield, and a red-and-black printed initial with a hand-ruled chapter heading, showing how early print borrowed manuscript decoration; a designer might take from them the ornamental wreath and the rubricated initial as models for emblems and display lettering.
