out of his grasp the sword dropped to the ground –
over his table, head over heels he tumbled, doubled up,
flinging his food and his two-handled cup across the floor –
he smashed the ground with his forehead, writhing in pain,
both feet flailing out, and his high seat tottered –
the mist of death came swirling down his eyes.

– Homer

The Odyssey, Book 22, lines 88-93. Eurymachus falls down dying and Odysseus’ revenge on another of the leading suitors is complete. Homer uses a metaphor to compare Eurymachus’ death to a swirling mist coming down over his eyes.
