Pliny, Epistulae I.VII:
“I hope to be there in Rome around the Ides of October, and to convince Gallus of all these things with your credit joined to mine. Even now you can assure him about my intention ἦ καὶ κυανέῃσιν ἐπ᾽ ὀφρύσι νεῦσε (‘he spoke, and Kronios nodded with his dark brows’). Why do I not always just carry on with you in Homeric lines?”
Me circa Idus Octobris spero Romae futurum, eademque haec praesentem quoque tua meaque fide Gallo confirmaturum; cui tamen iam nunc licet spondeas de animo meo ἦ καὶ κυανέῃσιν ἐπ᾽ ὀφρύσι νεῦσε. Cur enim non usquequaque Homericis versibus agam tecum?
