The most striking feature of the catalogue's geography is that it does not portray Greece in the Iron Age, the time of Homer. Minton places the catalogue within similar "enumerations" in Homer and Hesiod, and suggests that part of their purpose was to impress the audience with a display of the performer's memory. Visser argues that this knowledge was transmitted by the heroic myth, elements of which introduce each geographical section.

In the most recent extended study of the Catalogue, Edzard Visser, of the University of Basel, concludes that the Catalogue is compatible with the rest of the Iliad in its techniques of verse improvisation, that the order of the names is meaningful and that the geographical epithets evince concrete geographical knowledge. Īn intermediate theory is that the catalogue developed through a process of accretion during the poem's oral transmission and reflects gradual inclusion of the homelands of local sponsors by individual singers. Others contend that the Catalogue is based on the time of Homer himself in the eighth century BCE and represents an anachronistic attempt to impose contemporary information on events five centuries earlier. A few argue that parts of the recitation, such as the formulae describing places, date as early as the time of the Trojan War in the mid-13th century BCE, or possibly before. Following Milman Parry's theory of Homeric oral poetry, some scholars, such as Denys Page, argue that it represents a pre-Homeric recitation incorporated into the epic by Homer. If taken to be an accurate account, the Catalogue provides a rare summary of the geopolitical situation in early Greece at some time between the Late Bronze Age and the eighth century BCE. The consensus before the mid-twentieth century was that the Catalogue of Ships was not the work of the man who composed the Iliad, though great pains had been taken to render it a work of art furthermore, that the material of the text is essentially Mycenaean or sub-Mycenaean, while disagreement centers largely on the extent of later additions. The separate debate over the identity of Homer and the authorship of the Iliad and the Odyssey is conventionally termed "the Homeric Question". Dörpfeld notes that while in Odyssey Odysseus's kingdom includes Ithaca, Same, Dulichium, and Zacynthus, the Catalogue of Ships contains a different list of islands, again Ithaca, Same, and Zacynthus but now also Neritum, Krocylea, and Aegilips. In the debate since antiquity over the Catalogue of Ships, the core questions have concerned the extent of historical credibility of the account, whether it was composed by Homer himself, to what extent it reflects a pre-Homeric document or memorized tradition, surviving perhaps in part from Mycenaean times, or whether it is a result of post-Homeric development.
