Emanuelis Swedenborgii ... Regnum subterraneum sive minerale de ferro : de que modis liquationum ferri per Europam passim in usum receptis : de que conversione ferri crudi in chalybem : de vena ferri et probatione eius : pariter de chymicis praeparatis et cum ferro et victriolo eius factis experimentis &c. &c
Swedenborg's 1734 Latin treatise on iron and minerals, published at Dresden and Leipzig at the expense of Friedrich Hekel for a learned audience of metallurgists and natural philosophers. Its pictures are decorative woodcut headpieces and tailpieces: strapwork cartouches, scrolled acanthus, and vases of fruit set in symmetrical ornament, offering a designer dense, period-correct ornamental borders and frames.
