Joh. Joachimi Beccheri ... Physica subterranea profundam subterraneorum genesin e principiis hucusque ignotis ostendens : opus sine pari, primum hactenus et princeps
This is a 1738 Leipzig edition of Johann Joachim Becher's Physica subterranea, a natural philosophy treatise on the origin of subterranean bodies, edited by Georg Ernst Stahl and printed by the Weidmann press for scholars of chemistry and alchemy. Its four pictures are small woodcut typographic ornaments: a central monogram flanked by sprawling leafy scrolls, and a heart-shaped interlace of ribbon strapwork with foliage, the sort of decorative headpiece a designer could borrow for monograms, dividers, or heraldic emblems.
