An epic poem is a lengthy narrative work that often tells the story of heroic deeds and significant events. These poems typically feature a central hero, who embodies the values of their culture, and they explore themes such as bravery, honor, and the struggle between good and evil. Famous examples include Homer's Iliad and Virgil's Aeneid. Epic poems are usually written in a formal style and may include supernatural elements, such as gods or mythical creatures. They often begin with an invocation to a muse and employ various literary devices, such as similes and metaphors, to enhance the storytelling experience.
