By now the daylight covered the land, but Pallas,
shrouding them all in darkness,
quickly led the four men out of town.

– Homer

The Odyssey, Book 23, lines 420-422. Odysseus, Telemachus, Eumaeus and Philoetius depart the bloodied halls of the palace to travel to see Laertes. Athena cloaks them in darkness so that their enemies won’t see them leaving town.
