Meaning

    29–19 BC, Virgil, Aeneid, book VIIIBut dauntless Pallas bade them give not o'er the sacred festival, and spear in hand flew forward to a bit of rising ground, and cried from far: “Hail, warriors! what cause drives you to lands unknown, and whither bound? Your kin, your country? Bring ye peace or war?” Father Aeneas then held forth a bough of peaceful olive from the lofty ship, thus answering : “Men Trojan-born are we, foes of the Latins, who have driven us forth with insolent assault. We fain would see Evander. Pray, deliver this, and say that chosen princes of Dardania sue for his help in arms.”
