Javelins

But anon new foes / come swarming up, while ever and again / fast fall the showers of stones, and thick the javelins rain.

"Spare, O AEneas, spare a wretch, nor shame / thy guiltless hands, but let the dead repose. / From Troy, no alien to thy race, I came. / O, fly this greedy shore, these cruel foes! / Not from the tree – from Polydorus flows / this blood, for I am Polydorus. Here / an iron crop o'erwhelmed me, and uprose / bristling with pointed javelins."
