Quick as a thought goes flashing through a man
who’s traveled the world – "Ah to be there, or there!" –
as his mind swarms with journeys, fresh desires –
so quick in her eager flight flew noble Hera now
and scaling steep Olympus went among the gods,
the immortal powers thronging Zeus’s halls.

– Homer

The Iliad, Book 15, lines 99-104. Homer uses an epic simile of an eager world traveler to decribe how Hera rushes off to Mount Olympus to carry out Zeus’s instructions. Just before this passage an angry Zeus, having seen Hector’s armies being routed and Poseidon in the battle, accused Hera of treachery. He then ordered her to summon Iris and Apollo so as to put his plan into action to turn the tide of the war in favor of the Greeks.
