The _Doloneia_ is the most controversial book of the _Iliad_, its authenticity having been doubted since antiquity. Modern scholars are divided between those who regard it as a major interpolation by a later poet who was trained in the technique of epic composition and those who see it as the earliest manifestation of the very ancient theme of lochos. However, the first claim assumes the stylistic homogeneity of book 10, while the second sweeps out dictional and thematic difficulties by attributing them to the theme of ambush that is weakly represented in the extant corpus of archaic Greek epic. By applying sophisticated interpretive tools such as intratextual association, intertextual allusion, and oral neoanalysis, this book maintains that Iliad 10 is thematically consonant with the rest of the _Iliad_ and that it has evolved from an earlier Iliadic version after the addition of the Rhesus episode, which did not circulate as an independent composition but formed part of lost oral epic poetry with cyclic features that focused on the events after the death of Achilles.
