Oneness of Mind
HOMONOIA was the spirit (daimona) of concord, unanimity, and oneness of mind.
Her opposite number was Eris (Strife). She was sometimes numbered amongst the goddesses Praxidikai, (Exacters of Justice), who were said to be daughters of an early Theban King named Ogygos. As such Homonoia was probably closely identified with the Theban Goddess-Queen Harmonia (Harmony).
Pausanias, Description of Greece 5. 14. 9 (trans. Jones) (Greek travelogue C2nd A.D.) :
"Next [at Olympia] come an altar of Homonoia (Concord), another of Athena, and the altar of the Mother of the Gods (Metros Theon)."
Suidas s.v. Praxidike (trans. Suda On Line) (Byzantine Greek Lexicon C10th A.D.) :
"Praxidike (Exacter of Justice): A deity whose head alone is venerated. Mnaseas [Greek C2nd B.C.] in his treatise On Europe says that Soter (Saviour) and his sister Praxidike (Exacter of Justice) had a son Ktesios (Household) and daughters Homonoia and Arete, who were called Praxidikai (Exacters of Penalties) after their mother."
