Plutarch of Athens wrote commentaries on what Greek philosopher, whose writings constitute the first comprehensive system of Western philosophy?
Plutarch of Athens Plutarch of Athens (Greek: Πλούταρχος ὁ Ἀθηναῖος ; c. 350 – 430 AD) was a Greek philosopher and Neoplatonist who taught at Athens at the beginning of the 5th century. He reestablished the Platonic Academy there and became its leader. He wrote commentaries on Aristotle and Plato, emphasizing the doctrines which they had in common.
Eurytus (Pythagorean) Eurytus ( ; Greek: Εὔρυτος ; fl. 400 BC), was an eminent Pythagorean philosopher who Iamblichus in one passage describes as a native of Croton, while in another, he enumerates him among the Tarentine Pythagoreans. He was a disciple of Philolaus, and Diogenes Laërtius mentions him among the teachers of Plato, though this statement is very doubtful. It is uncertain whether Eurytus was the author of any work, unless we suppose that the fragment in Stobaeus, which is there ascribed to one Eurytus, belongs to this Eurytus.
