"West C.E.1966 p. 36, which, concerning Hesiod's list of names, says: "Its very heterogeneity betrays its lack of traditional foundation. Rhea, Zeus' mother, must be married to Kronos, Zeus' father. Hyperion, as father of Helios, must be put back to that generation; so must ancient and venerable personages as Oceanus and Tethys, Themis and Mnemosyne. By the addition of four more colourless names (Koios, Kreios, Theia, and Phoibe), the list is made up to a complement of six males and six females";cf. West C.E.1966, p. 200 on line 133."
