Besides Iliad 10 and the end of the Odyssey, book 11 of the Odyssey has been the most disputed passage in Homer in terms of authorship. This thesis presents the first modem scholarly commentary devoted to the book. It deals with the topic at more length than the commentaries of Stanford and Heubeck, and is more advanced than the commentary of Untersteiner, which is directed towards students. The introduction discusses the place of Od. 11 within the Odyssey, in terms of theme and narrative structure. It discusses the katabasis in early Greek myth and poetry, and argues that the ritual performed by Odysseus in Hades is not necromancy, but is based on an ordinary sacrifice to the dead. A survey is given of possible Near Eastern influences on the book. The 'problem' of Od. 11 is then addressed, in which it is argued that the book is not an interpolation, but that it is probably a later addition to a revised version ofthe poem. Hapax legomena and metre are also analysed. . The commentary itself is based broadly on three lines of interpretation: linguistic, literary, and historical. The main purpose of the thesis is to present aÃ‚Â· detailed commentary on which further discussion of the book may be based. It is argued that 440-64 and 565-600 are interpolations, but that the rest of the book is genume.
