Simoeis

In the genealogical scheme preserved in Greek sources and summarized in the provided material, Simoeis is one of the river-personifications born of the primordial water-deities Oceanus and Tethys. As with other named rivers in Greek myth, the name denotes both the physical watercourse in the Trojan plain and its divine personification, integrated into the wider family of elemental water divinities and local landscape deities.

The cited sources do not provide a detailed anthropomorphic or iconographic description of Simoeis. Literary references emphasize the river's physical character — described as a small river of the Troad and as a rapid mountain torrent whose springs rise on Mount Ida (Mount Cotylus), pass by Troy, and formerly join the Scamander — and treat the god primarily through its hydraulic manifestations rather than through specific bodily attributes in the supplied excerpts.

In the mythic episode summarized from Homer (Iliad 21), Simoeis functions as a river-god who can be summoned by a neighboring river-deity (Scamander) to swell streams and raise torrents in defense of Troy; the Iliad passage cited requests that Simoeis 'fill your streams... stir up all your torrents, stand high in a great wave, and rouse a mighty roar' against Achilles. This reflects the typical capabilities attributed to river-personifications in Greek epic — control over their waters and the mobilization of floods/torrents — and shows partisan alignment in divine contests. The supplied material also indicates that such river-deity action can be countered by other gods, as when Hephaestus uses fire to subdue Scamander in the same episode (the sources do not report a direct subduing of Simoeis in the provided excerpts).
