Homer's epics are said to be written by an ancient Greek blind poet Homer, who is revered as the greatest of ancient Greek epic poets. The epics include two great works of Greek history: the Iliad and the Odyssey . The two epics are the earliest works of Greek literature, and are among the greatest treasures of the ancient world, regarded by Westerners as the greatest epics in history. They have had an enormous influence on the history of literature and are of great value for the study of history, geography, archeology and folklore. Both the epics are divided into 24 volumes, the Iliad containing 15,693 lines and the Odyssey 12,110 lines. The Iliad is the oldest surviving work of Greek literature, which tells the story of the 10-year siege of the city of Troy. The Odyssey mainly centers on the Greek hero Odysseus and his journey home after the fall of Troy. Given the concise language, vivid plots and characters, Homer's epics are great pieces of literature and occupy an important position in the world literature history.
