Structurally the Trojan Battle Order is evidently inserted to balance the preceding Catalogue of Ships. It is, however, much shorter. Denys Page summarizes the prevailing explanation that "the Catalogues are substantially Mycenaean compositions rather expanded than altered by the Ionians" . Noting that the Greek catalogue occupies 265 lines but the Trojan catalogue only 61, Page wonders why the Ionian authors know so little about their native land and concludes they are not describing it but are reforming poetry inherited in oral form from Mycenaean times .
