Then he’d yoke his racing team to the chariot-harness,
lash the corpse of Hector behind the car for dragging
and haul him three times round the dead Patroclus’ tomb,
and then he’d rest again in his tents and leave the body
sprawled facedown in the dust.

– Homer

The Iliad, Book 24, lines 17-21. Achilles’s hatred for Hector is so extreme that it doesn’t stop even after he slays him. This passage describes the desecration of Hector’s body by Achilles, who drags it behind his chariot three times around the tomb of his friend Patroclus.
