When did he sailed to the island of aegean sea?

The context of "he" is unclear, but if you're referring to Odysseus from Homer's "The Odyssey," he sailed to various islands in the Aegean Sea during his journey home from the Trojan War, which is traditionally set in the 12th century BCE. Specific islands mentioned include Ithaca, where he ultimately returned, as well as others like ChiOS and Lesbos. If you are referring to a different historical figure or event, please provide more details for an accurate answer.
