1239 Johann Helfrich JÜNGKEN. Chymia experimentalis, sive Naturalis Philosophia Mechanica, ubi Prior Pars Generosiorum Remediorum fabricam ex Triplici Regno cum omnibus manipulationibus, fideliter exhibet. Pars altera Eadem Medicamenta, inter alia, ad quoscunque morbos generaliter adaptare docet. Adjectis Monitis Medicis Affectus Puerorum concernentibus. Nec non Experimentis Rerum Naturalium Principia, Commentarii loco, illustrantibus. Editio Prioribus longe auctior. 4° Francofurti ad Moenum: apud Johannem Maximilianum à Sande 1701 Young [Illustration:- Frontispiece engraving. 177x143mm. Various classical gods and goddesses give their help and approval to the work of Jungken. Zeus with his thunderbolts of fire, a multi-breasted goddess holds out a cornucopia with the fuits of the earth, Pan sends airy fumes of incense, and a Naiad or water goddess gives her blessing on the work. On the earth below to the right a number of winged cherubs have set up a furnace and are performing an alchemical operation. Some of them appear to respresent the four elements.]
