Die Adelsdocumente österreichischer Alchemisten und die Abbildung einiger Medaillen alchemistischen Ursprunges / von Alexander Bauer.
A German-language plate from an 1893 Vienna publication by Alexander Bauer, a study of Austrian alchemists' noble documents and alchemical medals, aimed at numismatists and historians of science. The plates show grids of silver-toned medals on black backgrounds, with inscriptions around their rims and emblematic designs such as suns, stars, serpents and mythic figures that a designer could draw on for seals, engraved emblems or vintage occult motifs.
