Asopus

They are duplicated a second time as supposed mortal kings who gave their names to the corresponding rivers.

Pausanias[6] writes that during the reign of Aras, the first earth-born king of Sicyonian land, Asopus, said to be son of Poseidon by Celusa (this Celusa otherwise unknown but possibly identical to Pero mentioned above), discovered for him the river called Asopus and gave it his name.

Pausanias[9] and Diodorus Siculus[10] also mention a daughter Harpina and state that according to the traditions of the Eleans and Phliasians, Ares lay with her in the city of Pisa and they had a son, Oenomaus, who Pausanias[11] says founded the city of Harpina named after her, not far from the river Harpinates.

The Bibliotheca[12] refers to Ismene daughter of Asopus who was wife of Argus Panoptes to whom she bore Iasus, the father of Io.

We find first in Pindar's odes[13] the sisters, Aegina and Thebe, here the youngest daughters of Boeotian Asopus by Metope who came from Stymphalia in Arcadia.

Both are abducted by the god Zeus, one carried to the island of Oenone later to be named Aegina and the other to Dirce's water to be queen there.

Euboea is near Boeotia, but Salamis and Aegina are regions that would perhaps associate better with the Phliasian Asopus.

In these tales Asopus discovers the truth about the abduction from Sisyphus, King of Corinth in return for creating a spring on the Corinthian Acropolis.

To make up the twelve Diodorus' list also adds Peirene (the famous spring in Corinth), Cleone (possible eponym of the small city of Cleonae on the road from Corinth to Argos according to Pausanias),[16] Ornia (possible eponym of the small town of Orneai south of Phlius), and Asopis.

He mentions no dispute about the others which suggests that in his time the assignment of Aegina to the Phliasian Asopus was generally admitted.
