These lines from the second book of the Aeneid introduce the night on which Troy falls. They have always been felt to be impressive: rich in allusion, noteworthy for the monosyllabic ending of the first line, and memorable for the majestic zeugma of the last two lines. Line 250 opens by incorporating a half line from Ennius: vertitur interea caelum cum ingentibus signis and closes with a near-translation of the substance of a half-line from Homer.
