MAIER, Michael (?1568-1622). Secretioris naturae secretorum scrutinium chymicum, Frankfurt: Johann Philipp Andreus for Georg Heinrich Oehrling, 1687. Small 4° (199 x 154mm.), half title, 50 engraved illustrations (lacking the final blank, most lower margins lightly waterstained, a few with very neat repairs, some light spotting). A reduced edition of Maier's Atalanta Fugiens (1617) without the musical scores and German verses, the plates showing allegorical and symbolical pictures of chemical processes. DSB notes that his writings "were highly valued and popular among alchemists ... Maier was a fervent believer in the transmutation of metals, which was for him a synonym of the word 'chymia.'"
