 It is thus no wonder that the lodestone has a prominent place in Porta’s performative practice and his theoretical endeavors. Porta takes the attractive powers of magnets on iron as a paradigm for magical attraction: the speculation is that all bodies have an inherent property to attract certain other bodies. In the second version of the Magia he plagiarized and popularized many basic insights from an unpublished Jesuit source (Leonardo Garzoni), for instance that the magnet has two opposite poles and the many tricks that could be performed by dint of these attractive and repulsive qualities of the lodestone (Copenhaver 1991, 2007, Ugaglia 2006, Sander 2016, Kodera 2020a).
