Exacter of Justice
PRAXIDIKE was the goddess or personified spirit (daimona) of exacting justice. She and her two daughters--Arete (Virtue) and Homonoia (Concord)--together formed a divine triad known as the Praxidikai.
Perhaps a daughter of ZEUS, though nowhere stated
PRAXI′DICE (Praxidikê), i. e. the goddess who carries out the objects of justice, or watches that justice is done to men. When Menelaus arrived in Laconia, on his return from Troy, he set up a statue of Praxidice near Gytheium, not far from the spot where Paris, in carrying off Helen, had founded a sanctuary of Aphrodite Migonitis (Paus. iii. 22. § 2). Near Haliartus, in Boeotia, we meet with the worship of Praxidicae, in the plural (ix. 33. § 2), who were called daughters of Ogyges, and their names are Alalcomenia, Thelxinoea, and Auilis (ix. 33. § 4; Suid. s. v.; Steph. Byz. s. v. Tremilê). Their images consisted merely of heads, and their sacrifices only of the heads of animals. With the Orphic poets Praxidice seems to be a surname of Persephone. (Orph. Argon. 31, Hymn. 28. 5.)
