Eunomia

Eunomia (Greek: Ευνομια, meaning "Good Order/Good Pasture") is the Greek goddess of good order and lawful conduct, and was numbered among the Horae. She is the daughter of Zeus and Themis.

Myths & Legends
Along with Dike and Eirene, she belonged to the second-generation Horae, goddesses of the seasons and the natural portions of time. Eunomia and her sisters also enacted their namesake upon mankind, and were seen as protectors of civilization and civil order, especially of cities. She opposed the Daimon Dysnomia (Lawlessness).

"'The Horai, as they are called, to each of them, according as her name indicates, was given the ordering and adornment of life, so as to serve to the greatest advantage of mankind; for there is nothing which is better to build a life of felicity than obedience to law (eunomia) and justice (dike) and peace (eirene).'"

"- Diodorus Siculus, Library of History 5. 72. 5 (trans. Oldfather)"

As one of the Horae of the seasons, she was also the spring-time goddess of green pastures (nomia in Greek), and was frequently worshipped in agriculture with her sisters.

Handmaiden
The Horae are often considered handmaidens to certain gods, usally affiliated with Helios/Apollo. Eunomia was frequently depicted on vase paintings as part of Aphrodite's retinue, and could be seen as representing lawful/obedient behavior in marraige. She has also been identified with Eurynome, mother of the Charites (Graces)
