Herakles crossed the Libyan desert. At the narrow channel that separates Europe and Africa, he built the Pillars of Herakles. The Sun was hot and Herakles threatened to shoot him with his bow and arrows. The Sun asked him not to do this. Herakles agreed. He borrowed the Sun's Golden Cup and sailed away in it. The Titan Oceanus tested Herakles' seamanship by causing violent waves. Herakles threatened to shoot Oceanus, too. Oceanus calmed the waves. Some say Herakles sailed in an urn and used his lion skin as a sail.
