In the Eighth Circle, among the evil counselors, a twin flame holds Ulysses and Diomedes. Ulysses tells how, after returning to Ithaca, he could not stay. He sailed west past the Pillars of Hercules, urging his aged crew with this famous speech. They glimpsed a mountain (Purgatory) before God sent a whirlwind that drowned them all.
Ulysses’ speech to his crew — a Renaissance call to human aspiration, though Dante places him in Hell for it.
