Final answer:
Odysseus was called away from home to fight in the Trojan War, a decision influenced by the Greek ideals of heroism, duty, and the pursuit of adventure and glory.
Step-by-step explanation:
Odysseus was originally called away from home to participate in the Trojan War, an epic struggle between the Greeks and the Trojans detailed in Homer's Iliad. His willingness to take on this challenge, despite the risks, likely stems from the values of his culture, which honor heroism, glory, and duty.
During the ancient Greek era, achieving kleos, or eternal glory, was of utmost importance, and embarking on such a perilous journey would certainly enhance Odysseus's reputation and ensure his memory lived on. As a king and a warrior, he would also be fulfilling his duty to his allies and demonstrating his leadership qualities.
Furthermore, the adventure of sailing to unknown places and gaining new experiences might have appealed to Odysseus's curiosity and intellect, as the Odyssey often depicts him employing cunning and wisdom to navigate challenges. These motives, combined, influenced Odysseus to leave Ithaca and join the Greek forces in the Trojan War.
