Das Geheimniss von dem Salz, als dem edelsten Wesen der höchsten Wohlthat Gottes in dem Reich der Natur ...
An 1770 German treatise by Friedrich Christoph Oetinger, published anonymously, on salt as a divine gift in nature, drawn from the C.G. Jung library and aimed at a learned readership of theologians and natural philosophers. The two pictures are a modern bookplate and an older printed woodcut ornament: the first is a black, gold and grey heraldic device with a winged angel, a shield, a star and a cross, while the second is a dense, fine-lined floral cartouche around a haloed figure, useful for designers studying bookplate heraldry against early woodcut framing.
