This article discusses transmutation medals as a sub-genre of “Gedächtnismünzen” which were in high esteem as media of baroque courtly self-fashioning and propaganda. It does so by contextualizing the medal commemorating a successful alchemical performance in Innsbruck on December 31 1716. Legend and image of the coin can be understood as an allusion to the prophecy of the Golden Age in Virgil’s fourth Eclogue, creating a meaning potential beyond the transmutation of metals. Given the frequent reception of the fourth Eclogue in panegyrical contexts we can assume that Karl III Philipp von Pfalz-Neuburg wanted the transmutation symbolized by the coin to be seen as a prosperous omen for his reign. However, it is possible that he also meant to insinuate a connection to the Emperor.
