Suetonius, Life of Tiberius 70
“He pursued the liberal arts of both languages most seriously. He was a follower of Messala Corvinus when it came to Latin oratory, a man whom he had observed while an adolescent. But he used to confuse his style with such excessive affectation and officiousness that he was considered more effective as an extemporaneous speaker than a prepared one.
He also wrote a lyric poem which had the title “A Lament on the Death of Lucius Caesar.” When he composed Greek poems, he imitated Euphorion, Rhianus, and Parthenius, those poets whose writing he liked most of all, and he placed their portraits in the public libraries among the older, famous authors. For this reason, many of the learned men of the time were in a competition dedicating many books about these men to Tiberius.
Still, he took the greatest care in knowledge of the stories of myth, to the point of absurdity and silliness. For he even used to quiz the grammarians, a class of men whom, as I said, he was really preoccupied with, posing questions like: “Who was the mother of Hecuba?” “What name did Achilles have among the girls?” “What were the Sirens accustomed to singing?”
LXX. Artes liberales utriusque generis studiosissime coluit. In oratione Latina secutus est Corvinum Messalam, quem senem adulescens observarat. Sed adfectatione et morositate nimia obscurabat stilum, ut aliquanto ex tempore quam a cura praestantior haberetur. Composuit et carmen lyricum, cuius est titulus “Conquestio de morte L. Caesaris.” Fecit et Graeca poemata imitatus Euphorionem et Rhianum et Parthenium, quibus poetis admodum delectatus scripta omnium et imagines publicis bibliothecis inter veteres et praecipuos auctores dedicavit; et ob hoc plerique eruditorum certatim ad eum multa de his ediderunt.3Maxime tamen curavit notitiam historiae fabularis usque ad ineptias atque derisum; nam et grammaticos, quod genus hominum praecipue, ut diximus, appetebat, eius modi fere quaestionibus experiebatur: “Quae mater Hecubae, quod Achilli nomen inter virgines fuisset, quid Sirenes cantare sint solitae.”
