 Much work from the past few years has concentrated on Marchia’s ideas in metaphysics, both in his commentaries on the Aristotelian work and in the various versions of his Sentences commentary. In particular, Marchia has been singled out for the theory of ‘supertranscendentals’ and for his explicit distinction between special and general metaphysics, foreshadowing an early modern development. There is some indication that Marchia’s innovations in metaphysics were influential into the fifteenth century, but more research is called for (see especially Folger-Fonfara 2008; Amerini 2008b; Aertsen 2012; Duba 2014a). In anticipation of the reaction of the scholarly community to these and other new studies and of the further contextualization of Marchia’s ideas, the present edition of this entry will concentrate on what is already known to be both distinctive and influential in Marchia’s thought.
