Ueber die Chursächsische Bergwerksverfassung : Ein Beytrag zur Statistik von Sachsen
A 1787 German treatise by Thomas Wagner, published by Beer, on the mining administration of Electoral Saxony, written as a contribution to the statistics of Saxony for officials and mining specialists. Its pictures are a red wax seal of a standing robed figure with lettering around its rim, and an engraved cartouche held up by two putti on clouds beneath a radiating sun, suggesting a designer could draw on heraldic seal shapes or the classical putto-and-shield vignette for frames and emblems.
