Then Pallas Athena granted Tydeus’ son Diomedes
strength and daring – so the fighter would shine forth
and tower over the Argives and win himself great glory.
She set the man ablaze, his shield and helmet flaming
with tireless fire like the star that flames at harvest.
bathed in the Ocean, rising up to outshine all other stars.

– Homer

The Iliad, Book 5, lines 1-6. The fierce Greek warrior and leader Diomedes is described in an epic simile as being like fire and blazing like a star, as goddess Athena gives him strength and daring to win great glory for himself.
