As soon as Idomeneus reached his well-built shelter
he strapped his burnished armor round his body,
grasped two spears and out he ran like a lightning bolt
the Father grips and flings from brilliant Olympus,
a dazzling sign to men – a blinding forked flash.
So the bronze flared on his chest.

– Homer

The Iliad, Book 13, lines 284-289. King of Crete and warrior Idomeneus gets ready to return to battle. An epic simile describes how he runs like a bolt of lightning flung by Zeus from Mount Olympus.
