The subject matter deeply reflects the culture that produced it.
Step-by-step explanation:
Epic is a genre that is highly associated with the heroic deeds of legendary characters. It always impacts the moral belief system of readers. The cultural impact of these long narratives is really high. It shapes the morality with the dealing of godly characters and the consequences faced by the hero for his misdeeds. This imparts a self-assessment to the readers to think about their actions and hence, assisting in the reformation of their beliefs. Homer's 'Iliad' and Odyssey are known as the greatest epics, are quite reflective of this thought.
