there in the midst strode powerful Agamemnon,
eyes and head like Zeus who loves the lightning,
great in the girth like Ares, god of battles,
broad through the chest like sea lord Poseidon.
Like a bull rising head and shoulders over the herds,
a royal bull rearing over his flocks of driven cattle –
so imposing was Atreus’ son, so Zeus made him that day,
towering over fighters, looming over armies.

– Homer

The Iliad, Book 2, lines 565-572. Godlike Agamemnon’s powerful presence among the Achaean warriors is dramatized in an epic simile, which attributes to him the eyes and head of Zeus, great girth of Ares, broad chest of Poseidon and power of a royal bull rearing over his cattle.
