query: When did Homer compose the Odyssey?
passage: Homer
The Homeric Question – concerning by whom, when, where and under what circumstances the Iliad and Odyssey were composed – continues to be debated. Broadly speaking, modern scholarly opinion falls into two groups. One holds that most of the Iliad and (according to some) the Odyssey are the works of a single poet of genius. The other considers the Homeric poems to be the result of a process of working and reworking by many contributors, and that "Homer" is best seen as a label for an entire tradition.[4] It is generally accepted that the poems were composed at some point around the late eighth or early seventh century BC.[5]
passage: Homer
Most contemporary scholars, although they disagree on other questions about the genesis of the poems, agree that the Iliad and the Odyssey were not produced by the same author, based on "the many differences of narrative manner, theology, ethics, vocabulary, and geographical perspective, and by the apparently imitative character of certain passages of the Odyssey in relation to the Iliad."[31][32][33][20] Nearly all scholars agree that the Iliad and the Odyssey are unified poems, in that each poem shows a clear overall design, and that they are not merely strung together from unrelated songs.[20] It is also generally agreed that each poem was composed mostly by a single author, who probably relied heavily on older oral traditions.[20] Nearly all scholars agree that the Doloneia in Book X of the Iliad is not part of the original poem, but rather a later insertion by a different poet.[20]
