Aeneid 7.655–669

655After them handsome Aventinus, son of handsome Hercules, displays over the grass his chariot decorated with the palm and his victorious horses, and on his shield bears his father's emblem, a hundred snakes and the Hydra girt with serpents; 659whom, in the woods of the Aventine hill, the priestess Rhea brought forth in secret into the borders of light, a woman mated with a god, after the Tirynthian, victorious, having killed Geryon, reached the Laurentine fields and bathed his Iberian cattle in the Tyrrhenian river. 664They carry javelins in their hands and cruel pikes to war, and they fight with the smooth blade and the Sabine spit. 666He himself, on foot, swinging a huge lion's skin, bristling with fearsome shaggy mane, with its white teeth, worn on his head, entered the royal palace in this way, rough and wild, his shoulders wrapped in the garb of Hercules.
