The Iliad, together with the Odyssey, is one of two ancient Greek epic poems traditionally attributed to Homer. The poem is commonly dated to the 8th or 7th century BC, and many scholars believe it is the oldest extant work of literature in the Greek language, making it the first work of European literature. The existence of a single author for the poems is disputed as the poems themselves show evidence of a long oral tradition and hence, multiple authors. The poem concerns events during the tenth and final year in the siege of the city of Iliun, or Troy, by the Greeks. (Summary adapted from Wikipedia by Karen Merline.)
