So he triumphed
and now he was bent on outrage, on shaming noble Hector.
Piercing the tendons, ankle to heel behind both feet,
he knotted straps of rawhide through them both,
lashed them to his chariot, left the head to drag
and mounting the car, hoisting the famous arms aboard,
he whipped his team to a run and breakneck on they flew,
holding nothing back.

– Homer

The Iliad, Book 22, lines 465-472. Achilles, after killing Hector in revenge for the death of his dead friend Patroclus, goes on to defile and mistreat the body of Hector, cutting a hole through Hector’s tendons, putting straps through them and tying the body to his chariot and dragging it at full speed for all to see. This is a barbaric act by Achilles and speaks to his uncontrollable rage and total lack of compassion for the fallen Trojan prince and his family.
