 As mentioned above, Hadot (1968) made a case for identifying Porphyry as the author of the so-called Anonymous commentary on Plato’s Parmenides. The late ancient author of this commentary, extant in mere fragments, takes the Parmenides to present Plato’s ontological view. The commentary employs a notion of the One as an ineffable first principle that according to Hadot makes it post-Plotinian. However, in the commentary the distinction between the first and the second hypostasis is somewhat blurred: the ineffable One is somehow also at the same time the first member (“Father”) in a triad of being, life and intelligence and in this context identical with being. Positing a first principle that is a part of such a composite is surely un-Plotinian. If Hadot’s identification of the author with Porphyry is right, Porphyry indeed held metaphysical views that differ significantly from those of Plotinus. However, even if Hadot’s hypothesis about Porphyry as the author of the commentary quickly won wide acceptance, in later years it has suffered several blows at the hands of scholars with the result that it must be considered highly questionable (see, e.g., Edwards 1990, Bechtle 1999, Corrigan 2000, Rasimus 2011). The discovery that most of the supposedly Porphyrian characteristics of the Parmenides commentary are to be found in pre-Porphyrian Gnostic texts (unavailable to Hadot in the 1960s) seems especially troublesome for Hadot’s thesis (see Rasimus 2011). Porphyry’s authorship has, however, been recently defended by Chiaradonna (2014). Smith (1987, 2007), though unwilling to assert Porphyry as the author, holds that it comes from his circle and, hence, is definitely post-Plotinian.
