Ευαδνη Euadnê Evadne Very holy
(eu-, adnos)
EUADNE (or Evadne) was the Naiad Nymph of a well or fountain of the town of Argos (southern Greece). She was, somewhat curiously, called the daughter of the River-God Strymon in the distant lands of Thrake.

Euadne married Argos the eponymous king of the land, a son of Zeus and Niobe, and bore him four sons: Kriasos the next king of Argos, Ekbasos father of Argos Panoptes (a hundred-eyed giant), Peiras father of the serpentine-monster Ekhidna, and Epidauros founder of his self-named town.

Euadne was probably closely identified with Ismene, the wife of Argos according to others.

Pseudo-Apollodorus, Bibliotheca 2. 3 (trans. Aldrich) (Greek mythographer C2nd A.D.) :
"Niobe the first mortal woman with hom Zeus had sex, bore Zeus a son Argos . . . He got the rule and named the Peloponnesos Argos after himself. He married Euadne, the daughter of Strymon and Neaira, and sired Ekbasos, Peiras, Epidauros, and Kriasos. The son of Ekbasos was Agenor, and his son was Argos surnamed Panoptes. This man had eyes all over his body . . .
It is also said that he waited until Ekhidna fell asleep, and then killed her. She was a daughter of Tartaros and Ge (Earth), who would kidnap travellers passing by . . .
Argos [son of Niobe] and Asopos' daughter Ismene had a son Iasos, who is alleged to be the father of Io."
[N.B. Both Apollodorus and Pausanias, below, appear to have sourced their genealogies and stories from Epimenides.]

Pausanias, Description of Greece 8. 17. 6 (trans. Jones) (Greek travelogue C2nd A.D.) :
"Epimenides the Kretan (Cretan) [poet C5th B.C.] has also made Styx a daughter of Okeanos . . . makes her the mother of Ekhidna by Peiras (End), whoever Peiras was."

Pseudo-Hyginus, Fabulae 145 (trans. Grant) (Roman mythographer C2nd A.D.) :
"Nioba was the first mortal to be embraced by Jove [Zeus]; to her was born Argus who named the city Argos from his own name. From Argus and Evadne, Criasus, Piranthus [Peiras], and Ecbasus were born; from Piranthus and Callirhoe, Argus, Arestorides, and Triopas." [N.B. The genealogy appears to be corrupt.]
