Verae alchemiae artisque metallicae, citra aenigmata is a 1561 alchemical treatise printed in Basel by Heinrich Petri and Pietro Perna, written for scholars and practitioners of metallurgy and the occult arts. The pages are dense blocks of Latin roman type with decorative initial letters, large capitals and running headers, and a designer might take their rhythm of tight columns and ornamental openings for typographic layouts.
