€ 150Weinmann (1683-1741) was a Regensburg apothecary who organised this massive work, which was published from 1737-1745 and contained over a thousand colour-printed mezzoprint plates representing thousands of plants. The mezzotint process used had been invented by Johann Teyler in the Netherlands around 1688. As practised here by Bartholomäus Seuter (1678-1754) and Johann Elias Ridinger (1698-1767), it was really a combination of etching and mezzotint, which made possible delicate lines and a very fine grain. The addition of handtinting brought about unusual and subtle effects. Some of the best work was done in later volumes by Johann Jakob Haid (1704-1767), who also provides portraits of Weinmann and Bieler (Hunt). The plates are after drawings by Georg Dionysus Ehret, his first published botanical illustrations (although unsigned), N. Asamin and others. Probably from the Dutch edition, which is preferably to the German one Phytanthoza iconographia, as the quality of the paper and finishing is much higher.
