Greek heroes are legendary figures from ancient Greek mythology known for their extraordinary feats and adventures. They often possess divine ancestry, such as being the offspring of a god and a mortal. Famous heroes include Hercules, known for his strength and the Twelve Labors, and Achilles, a key warrior in the Trojan War. These heroes typically embark on epic quests, facing challenges that test their bravery and skills. Their stories often explore themes of honor, sacrifice, and the struggle between good and evil. Many of these tales were passed down through oral tradition and later written down by poets like Homer and Virgil.
