Caystrus

Surviving summaries identify Caystrus primarily as the god of the river by the same name in Lydia (now called Küçük Menderes). Secondary summaries (Pantheon.org citing ancient authors) report that Caystrus was father to an autochthonous son 'from whom the city of Ephesus received its name.' The supplied materials do not preserve a fuller foundation myth or detailed genealogical narrative in the quoted excerpts; the relationship appears in modern summaries of ancient sources rather than in an extended primary tale in the provided set.

The provided sources do not record any anthropomorphic or iconographic description of Caystrus. The entity is presented in the materials chiefly as a geographic river-name that is personified as a local river-god; no bodily form, attributes, or visual motifs are given in the surveyed excerpts. The absence of description is noted in the sources rather than supplemented by conjecture.

The extant excerpts do not list specific supernatural acts, powers, or behaviors for Caystrus. As attested, Caystrus functions as the presiding spirit or deity of the river bearing the same name and plays an etiological/genealogical role in local civic myth (a son linked to the naming of Ephesus). Broader associations implicit in the category 'river-god' (influence over the river, the plain, and local fertility) are not explicitly detailed in the supplied texts and therefore are reported only as contextual roles rather than documented feats.
