There is no mention of Eucleia in
Hesiod's
Theogony, and no early genealogy is known for the goddess. However, a fragment of
Euripides suggests that as a personified abstraction Eucleia was, by the fifth century BC at least, considered to be the daughter of another personified abstraction
Ponos (Toil). In
Athens, Eucleia was a personified abstraction, representing good reputation and glory. She shared a common Athenian sanctuary and priest with another personified abstraction
Eunomia (Good Order). Their common priest also served as the cosmetes, the official who was responsible for the training of Athens' young military cadets, the
ephebes.
Roland Hampe has argued that the cosmetes was probably also responsible for moral supervision of the Athenian young women. The geographer
Pausanias reports that a sanctuary of Eucleia (with no mention of Eunomia) was set up in or near the Athenian market as a
thank-offering for the victory at
Marathon (490 BC). The
Greek lyric poet Bacchylides, in Ode 13 (c. 485-483 BC), also associates Eucleia with Eunomia on the island of
Aegina, as one of the protectors of the state (
polis), saying that
Arete (Excellence) "guides the state with garland-loving Eucleia, and sound-minded Eunomia". A reserved seat inscription for Eucleia and Eunomia's common priest at Athen's
Theater of Dionysus, attests to their cult association during the
Roman imperial period. The name "Eucleia", in reference to a goddess, was widespread. In addition to the Athenian personified abstraction, there are also references to a goddess Eucleia in
Boetia,
Locris,
Corinth, and
Delphi. According to
Plutarch, although Eucleia was generally regarded as the same as Artemis, others said she was a daughter of
Heracles and
Myrto, and that she died a virgin and was worshipped among the
Boeotians and the
Locrians: Eucleia religious festivals were celebrated in
Corinth, and
Delphi. The Corinthian festival was multi-day and hence of some importance. According to
Xenophon, a "sacrilegious" mass murder took place in the Corinthian market place on "the last day" of the Eucleia festival. The Eucleia at Delphi was an important festival for the Labyads who offered sacrifices at the festival for newlyweds and newborns that were being initiated into the family. From the festival name comes Eucleios, the name of a month for several, particularly Doric, communities, such as
Corfu,
Astypalaia,
Byzantium, and
Taormina. In
Paros and
Epiros, military generals (
stratêgoi) offered dedications to Eucleia along with
Aphrodite,
Zeus Aphrodisios,
Hermes, and Artemis. The connection between the Eucleia paired with Eunomia at Athens, and the Eucleia of Boetia and elsewhere is unclear.
Martin P. Nilsson saw little connection between what he calls this Locrian-Boeotian-Corinthian wedding goddess (
Hochzeitsgöttin), and the Eucleia at Athens, other than a shared name. That the temple of Eucleia at Athens was set up as a thank-offering, "indicates a different sort of cult" than the one in Boeotia. ==Epithet of Artemis==
