  Petrizi names the philosophers whom he treated in his Interpretation: Orpheus, Parmenides, Zeno, Plato, Aristotle, Alexander of Aphrodisias, Porphyry and the Fathers of the Church (Petrizi, Opera I, pp. XXVI–LII; Alexidse, pp. 148–168). He held Platonic philosophy in particularly high esteem. Its representatives included in his view both Plato’s predecessors (Orpheus, Pythagoras, etc.) and the neo-Platonists. He calls Plato ‘the philosopher of the day’ (Petrizi, Opera I, p.  XXVII). When Petrizi speaks of the ‘philosopher’, he means Proclus. By contrast, in the Latin middle ages, the designation philosophus was reserved for Aristotle.
