The term "heroic epic" in mythology refers to a long narrative poem that recounts the deeds of a hero and the struggles they face, often involving gods and supernatural elements. A prime example of a heroic epic is Homer's "Iliad", which focuses on the Trojan War and the Greek hero Achilles. These epics serve to preserve cultural values, convey moral lessons, and explore themes such as honor, bravery, and the nature of heroism, making them essential to understanding ancient civilizations' worldviews.
