Highlighted in the comments so far on the cosmic river Ōkeanos is the role of this world-encircling fresh-water stream as a boundary delimiting light from darkness, wakefulness from sleep, life from death. Such delimitations, as we have seen, are elaborated poetically in contexts that picture the rising of the sun out of the waters of the Ōkeanos at sunrise—after its setting into these same waters at sunset. See the comments on I.07.421–423 and I.08.485–486. And now, in the context of a scene that evokes the themes of hieros gamos ‘sacred sexual intercourse’, we find that the role of Ōkeanos evokes also the themes of theogony and cosmogony. These themes are conveyed by wording that points to the role of Ōkeanos as a personified god who combines with a personified goddess Tēthus in prototypically initiating a genesis ‘generating’ of gods, as we see here at I.14.201, and even a genesis ‘generating’ of all things, as we will see at I.14.245–246–246a.
