Patroclus armed himself in Achilles’ gleaming bronze.
First he wrapped his legs with the well-made greaves,
fastened behind the heels with silver ankle-clasps,
next he strapped the breastplate round his chest,
blazoned with stars – swift Achilles’ own –
then over his shoulder Patroclus slung the sword,
the fine bronze blade with its silver-studded hilt,
and then the shield-strap and the sturdy, massive shield
and over his powerful head he set the well-forged helmet.

– Homer

The Iliad, Book 16, lines 156-164. Patroclus prepares for battle by donning Achilles’s armor, as the Trojans succeed in setting fire to one of the Achaean ships in the battle for the ships.
