Kleos (κλέος) is an Ancient Greek word meaning glory, renown, or fame, particularly in the context of heroic deeds and immortality through remembrance. It comes from the verb kleiō (κλείω), meaning “to celebrate” or “to make famous.”
In Homeric epic, kleos is a central concept, especially in The Iliad and The Odyssey, where heroes strive for eternal glory through their actions in battle or great journeys. It is often linked to the idea of kleos aphthiton (κλέος ἄφθιτον), or “undying fame”, which is the ultimate goal for a warrior—to be remembered forever.
