The contention that the Homeric epics, and perhaps also the Hesiodic poems and the Homeric Hymns, are the products, directly or at a very short remove, of a tradition of orally improvised poetry is widely accepted as a basic premiss in Homeric criticism. The cogency of the argument depends on the frequency and characteristic use of formulae in the early hexameter poetry, and their rarity in the literature of Classical, Hellenistic, and Roman times, which is known or assumed to have (...) been composed in the study. The reasoning appears to me valid, but in some respects overstated or ambiguously stated in recent publications, and the first fault arises out of the second. (shrink)
