This conclusion served to link the “Theogony” to what must have been a distinct poem, the “Catalogues of Women”. This work was divided into four (Suidas says five) books, the last one (or two) of which was known as the “Eoiae” and may have been again a distinct poem: the curious title will be explained presently. The “Catalogues” proper were a series of genealogies which traced the Hellenic race (or its more important peoples and families) from a common ancestor. The reason why women are so prominent is obvious: since most families and tribes claimed to be descended from a god, the only safe clue to their origin was through a mortal woman beloved by that god; and it has also been pointed out that ‘mutterrecht’ still left its traces in northern Greece in historical times.
The following analysis (after Marckscheffel)  will show the principle of its composition. From Prometheus and Pronoia sprang Deucalion and Pyrrha, the only survivors of the deluge, who had a son Hellen (frag. 1), the reputed ancestor of the whole Hellenic race. From the daughters of Deucalion sprang Magnes and Macedon, ancestors of the Magnesians and Macedonians, who are thus represented as cousins to the true Hellenic stock. Hellen had three sons, Dorus, Xuthus, and Aeolus, parents of the Dorian, Ionic and Aeolian races, and the offspring of these was then detailed. In one instance a considerable and characteristic section can be traced from extant fragments and notices: Salmoneus, son of Aeolus, had a daughter Tyro who bore to Poseidon two sons, Pelias and Neleus; the latter of these, king of Pylos, refused Heracles purification for the murder of Iphitus, whereupon Heracles attacked and sacked Pylos, killing amongst the other sons of Neleus Periclymenus, who had the power of changing himself into all manner of shapes. From this slaughter Neleus alone escaped (frags. 13, and 10-12). This summary shows the general principle of arrangement of the “Catalogues”: each line seems to have been dealt with in turn, and the monotony was relieved as far as possible by a brief relation of famous adventures connected with any of the personages–as in the case of Atalanta and Hippomenes (frag. 14). Similarly the story of the Argonauts appears from the fragments (37-42) to have been told in some detail.
