Although these paragraphs were written with specific reference to our arguments about Iliad 10, they are equally applicable to the theoretical infrastructure on which we have built the Homer Multitext. The Multitext takes as its starting point the historical documents that transmit the Homeric Iliad and Odyssey from antiquity, including quotations in ancient authors, papyrus fragments, medieval manuscripts and their accompanying scholia. Instead of privileging one source over another, or culling from among them to produce a single authoritative text, we value each of these documents individually for the multiforms that they transmit, and the insight that they might provide into the poetics, composition, and performance of these song traditions. The Iliad and Odyssey were at one time dynamic and evolving, and the particular nature of oral epic song, as described by Milman Parry and Albert Lord, allowed layer upon diachronic layer of this poetry to be preserved within the system of formulaic language as it evolved. Greg’s diachronic view of Homeric poetry enables him (and us and all of his students) to appreciate the multiformity attested in the surviving historical witnesses as the byproduct of a system that evolved over many centuries, and to search for meaning in the poetry that was created over time and passed down through performance.
