14o JOURNAL OF THE HISTORY OF PHILOSOPHY 34: X .JANUARY t996 method of reading the dialogues in an ascending order of philosophical importance need not be reflected completely or consistently in the tetralogical scheme. I pass over the account of Thrasyllus' logos-theory which Tarrant derives from an elusive section of Porphyry's commentary on Ptolemy's Harmonics in order to discuss the more important conclusions he draws in chapter 6, "The Neopythagorean Parmenides." By carefully sifting passages in Proclus' commentary on the Parmenides and Simplicius' commentary on the Physics, Tarrant adds to our still incomplete picture of the development of a Neoplatonic ontology out of the hypotheses of Plato's Parmenides. E. R. Dodds made a brilliant case in this regard for Moderatus, the late first century A.D. Neopythagorean, but Tarrant finds even earlier evidence for it by ascrib- ing to Thrasyllus this quasi-Neoplatonic, fivefold ontology: transcendent One, one-being = the intelligibles, the third principle = the soul, physical particulars, matter. Epistle 2's "King of all" is drawn into Tarrant's net as an "esoteric" or symbolic emblem of the transcendent One. He argues plausibly that, since Thrasyllus was instrumental in getting this and other Epistles included in the standard edition of Platonic works, the connections he finds among the Parmenides, the Epistles, and pas- sages in the latter commentators are not facile and are worthy of..
