Ammianus Marcellinus, Constantius et Julianus 17.11
“Once these facts were known in the court of Constantius—for it was required that Caesar should report about all of his deeds to Augustus like any inferior—everyone who previously had power in the palace and were already professors of learned praise, they were converting Julian’s correctly considered and successfully accomplished deeds into mockery, wisecracking without end like this: “This girl-goat, not a man, is getting hateful because of his victories”; they picked on Julian because he was hairy, calling him a “talking mole”, or “a purple-robed ape”, or “a Greek professor” and other similar insults.
Because they were echoing in the ears of an emperor who longed to hear these kinds of things, they were also trying to hide his virtues with shameful speeches, calling him lazy and fearful and one who dressed up his failures with polished words. This was not happening then for the first time.”
Haec cum in comitatu Constantii subinde noscerentur—erat enim necesse, tamquam apparitorem, Caesarem super omnibus gestis ad Augusti referre scientiam—omnes qui plus poterant in palatio, adulandi professores iam docti, recte consulta prospereque completa vertebant in deridiculum, talia sine modo strepentes insulse: “In odium venit cum victoriis suis capella, non homo,” ut hirsutum Iulianum carpentes, appellantesque “loquacem talpam” et “purpuratam simiam” et “litterionem Graecum,” et his congruentia plurima. Atque ut tintinnabulaprincipi resonantes, audire haec taliaque gestienti, virtutes eius obruere verbis impudentibus conabantur ut segnem incessentes et timidum et umbratilem, gestaque secus verbis comptioribus exornantem; quod non tunc primitus accidit.
