In the title page for Daniel Sennert’s Institutionum medicinæ Libri V, Matthäus Merian the Elder (1593–1650) did not only transfer elements from the engraved title page of Andreas Libavius’s (1560–1616) Alchymia. The engraver made even stronger reference to Heinrich Khunrath’s (~1560–1605) Philosophical Athanor, an object that was at once a Paracelsian laboratory utensil, a spiritual vehicle and a lavishly produced art chamber piece – a genuine Artificium. Merian thus allusively visualised Sennert’s (1572–1637) iatrochemical approach, which also combined Paracelsian elements, in the pictorial programme of the title page. For, on the one hand, Sennert wanted to emulate Libavius, on the other hand, he also insisted on the ostentatious depiction of the philosophical furnace of an Paracelsian, whose nature-magical views he thus conceded an unmistakable place within his own doctrinal edifice.
