Arius Didymus in Wikipedia
Arius Didymus (Areius, Greek: Ἄρειος; 1st century BC-1st century AD) was a citizen of Alexandria, and a Stoic philosopher in the time of Augustus, who esteemed him so highly, that after the conquest of Alexandria, he declared that he spared the city chiefly for the sake of Arius. Arius as well as his two sons, Dionysius and Nicanor, are said to have instructed Augustus in philosophy. He is frequently mentioned by Themistius, who says that Augustus valued him not less than Agrippa. From Quintilian it appears that Arius also taught or wrote on rhetoric. He is presumably the "Arius" whose Life was among those in the missing final section of book VII of Diogenes Laėrtius.
It's not good to have too many Caesars
According to Plutarch Arius advised Augustus to execute Caesarion, the son of Cleopatra and Julius Caesar, with the words "ouk agathon polukaisarie" ("it's not good to have too many Caesars"), a pun on a line in Homer. The original line was "ouk agathon polukoiranie": "Too many leaders are not good" or "the rule of many is a bad thing" (Homer, Iliad, Bk. II. vers. 204 and 205). In Greek "polukaisarie" is a variation on "polukoiranie". "Kaisar" (Caesar) replacing "Koiran(os)", meaning "leader".
Arius Didymus is usually identified with the Arius whose works are quoted at length by Stobaeus, summarising Stoic, Peripatetic and Platonist philosophy. That his full name is Arius Didymus we know from Eusebius, who quotes two long passages of his concerning Stoic views on God; the conflagration of the Universe; and the soul.
