Hector bore his round shield in the forefront, blazing out
like the Dog Star through the clouds, all withering fire,
then plunging back in the cloud-rack massed and dark –
so Hector ranged on, now flaring along me front,
now shouting his orders back toward the rear,
all of him armed in bronze aflash like lightning
flung by Father Zeus with his battle-shield of thunder.

– Homer

The Iliad, Book 11, lines 69-75. On the battlefield on the Trojan side, the troops mass around Hector. In a dramatic epic simile, the Trojan warrior is likened to a blazing star as if lit up by lightning from Zeus.
