Suetonius, Lives of Illustrious Men, On Grammarians 16
“Quintus Caecilius Epirota, a native of Tusculum and a freedman of Atticus the Roman Knight (the one who corresponded with Cicero), was suspected of taking advantage of his patron Marcus Agrippa’s daughter when he was teaching her and was removed for this. Then he went to Cornelius Gallus and lived with him in a very familiar way, the very matter which was presented against him by Augustus among the most serious crimes.
After Gallus’ conviction and death, Epirota opened a school but received only a few students and adolescents, barring others younger unless he was not able to deny the parent. He is the first reported to have spontaneous debates in Latin and to begin to read Vergil and the recent poets, which is implied in the little verse of Domitius Marsus: “Epirota, little nurse of baby bards”
XVI. Q. Caecilius Epirota, Tusculi natus, libertus Attici equitis Romani, ad quem sunt Ciceronis epistulae, cum filiam patroni nuptam M. Agrippae doceret, suspectus in ea et ob hoc remotus, ad Cornelium Gallum se contulit vixitque una familiarissime, quod ipsi Gallo inter gravissima crimina ab Augusto obicitur. Post deinde damnationem mortemque Galli scholam aperuit, sed ita ut paucis et tantum adulescentibus praeciperet, praetextato nemini, nisi si cuius parenti hoc officium negare non posset. Primus dicitur Latine ex tempore disputasse, primusque Vergilium et alios poetas novos praelegere coepisse, quod etiam Domitii Marsi versiculus indicat: Epirota, tenellorum nutricula vatum.
