Gründliche Ausslegung und warhafftige Erklerung der rythmorum Fratris Basilii Valentini Monachi.
This is a 16th-century German alchemical treatise, a commentary on verses attributed to the monk Basil Valentine, printed for scholars and practising alchemists; its woodcut pictures are small and crude. The first picture is a dense ornamental scroll-and-foliage device on a plain ground, a usable motif for border or emblem work. The second is a brick tower with arched furnace-like openings, a cupola, flag and scrolled finials in a ruled frame, showing how early printers combined architecture and symbol in simple black line.
