Ille ego, qui quondam gracili modulatus avena

Spurious opening lines of the Aeneid (tr. Stanley Lombardo), not found in the earliest manuscripts. Attributed to Virgil on the authority of "the grammarian Nisus", who claimed to have "heard from older men" that Varius had "emended the beginning of the first book by striking out" the four introductory lines, as reported in Suetonius' Life of Vergil http://penelope.uchicago.edu/Thayer/E/Roman/Texts/Suetonius/de_Poetis/Vergil*.html, 42 (Loeb translation). John Conington, in his Commentary on Vergil's Aeneid, remarks: "The external evidence of such a story it is impossible to estimate, but its existence suspiciously indicates that the lines were felt to require apology" (Vol. II, p. 30).
