[16] An unnamed daughter of his is said to have consorted with Hecaterus and thus became the mother of the five Hecaterides, nymphs of the rustic dance.
[18][19] The Clementine Recognitions mentions Phthia, a daughter of Phoroneus, who became the mother of Achaeus by Zeus.
[20] Hyginus' genealogy expresses the position of Phoroneus as one[21] of the primordial men, whose local identities differed in the various regions of Greece,[22] and who had for a mother the essential spirit of the very earth of Argos herself, Argia.
[24] Poseidon and Hera had vied for the Argive when the primeval waters had receded, Phoroneus "was the first to gather the people together into a community; for they had up to then been living as scattered and lonesome families".
He was worshipped in Argos with an eternal fire that was shown to Pausanias in the 2nd century CE, and funeral sacrifices were offered to him at his tomb-sanctuary.
