In the 6th century, the Neoplatonist philosopher Simplicius, who was persecuted for his pagan beliefs during the reign of Justinian, wrote an extant commentary on the Enchiridion.

Simplicius was a disciple of Ammonius Hermiae, and Damascius, and was consequently one of the last members of the Neoplatonist school.

The knowledge we have of them derives from accounts of later philosophical writers ( especially Aristotle, Plutarch, Diogenes Laërtius, Stobaeus and Simplicius ), and some early theologians, ( especially Clement of Alexandria and Hippolytus of Rome ).

For an expanded account of Zeno's arguments as presented by Aristotle, see Simplicius ' commentary On Aristotle's Physics.

A general idea of the content of On Speeds can be gleaned from Aristotle's Metaphysics XII, 8, and a commentary by Simplicius of Cilicia ( 6th century CE ) on De caelo, another work by Aristotle.

He was a widower with two children when he was elected to succeed Pope Simplicius in 483.

Seven philosophers, among whom were Simplicius, Eulamius, Priscian, and others, with Damascius, the last president of the Platonist school in Athens at their head, resolved to seek protection at the court of the famous Persian king Chosroes, who had succeeded to the throne in 531.

Only at the end of his explanation of the treatise of Epictetus, Simplicius mentions, with gratitude, the consolation which he had found under tyrannical oppression in such ethical contemplations ; which might suggest that it was composed during, or immediately after, the above-mentioned persecutions.

Simplicius addition, the eight books in the Commentaries Aristotle, that " the places where they were deposited and preserved corpses of the nine heroes got from Hercules Tespiesi and came to Sardinia with the colony of Iolaus, became the famous oracles.

Simplicius tells us he had never met with the verses about the earth stretching infinitely downwards ( fr.

Acacius, who had now fully ingratiated himself with Zeno, suggested the emperor to take sides with Mongus in spite of the vehement opposition of Simplicius.

John Talaia refused to subscribe to it and retired to Rome ( 482-483 ), where his cause was taken up with great vigour by letters of Pope Simplicius urging Acacius to check the progress of heresy elsewhere and at Alexandria.

According to a story reported by Simplicius, Plato posed a question for Greek astronomers: " By the assumption of what uniform and orderly motions can the apparent motions of the planets be accounted for?

Likewise we find mention of monographs of Theophrastus on the early Greek philosophers Anaximenes, Anaxagoras, Empedocles, Archelaus, Diogenes of Apollonia, Democritus, which were made use of by Simplicius ; and also on Xenocrates, against the Academics, and a sketch of the political doctrine of Plato.

There is some evidence for what today would be considered strictly scientific research: Simplicius reports that Plato had instructed the other members to discover the simplest explanation of the observable, irregular motion of heavenly bodies: " by hypothesizing what uniform and ordered motions is it possible to save the appearances relating to planetary motions.
