As a stallion full-fed at the manger, stalled too long,
breaking free of his tether gallops down the plain,
out for his favorite plunge in a river’s cool currents,
thundering in his pride – his head flung back, his mane
streaming over his shoulders, sure and sleek in his glory.
knees racing him on to the fields and stallion-haunts he loves –
so down from Pergamus heights came Paris, son of Priam,
glittering in his armor like the sun astride the skies,
exultant, laughing aloud, his fast feet sped him on.

– Homer

The Iliad, Book 6, lines 604-672. Paris, who has been scolded by his brother Hector for avoiding battle, now sets off for the battle lines. Here in this epic animal simile he is compared to a proud stallion, sure in his glory, breaking free of his tether and galloping on to the battlefield.
