Themis

Themis was a Titaness, daughter of Uranus and Gaia, and her name is also the ordinary Greek word for divine law, the settled order of custom and right conduct that both gods and mortals were expected to observe. Hesiod's Theogony makes her Zeus's second wife, after Metis, and credits their union with the Horai, goddesses of the seasons and of justly ordered time, and the Moirai, the three Fates who determine the span of a mortal life. Themis is regularly shown seated beside Zeus on Olympus in later literature, less a ruling consort than a personification of the lawful order his rule was supposed to embody, and she is repeatedly the deity who convenes assemblies of gods or announces their decisions, a function tied directly to what her name means. Ancient tradition also gave her an early and important role at Delphi: before Apollo took possession of the oracular shrine, Themis was said to have held it herself, inheriting it from her mother Gaia and, in some versions, handing it on peaceably to Apollo or to her sister Phoebe before Apollo's own succession, making her one of the few Titans credited with founding rather than merely predating a major religious institution. a rare instance of an orderly transfer of sacred authority in a mythology otherwise dominated by conquest.

Unlike several of her fellow Titans, Themis was a genuinely worshipped goddess with real cult centers across Greece. At Rhamnous in Attica, she shared the sanctuary later famous for its temple of Nemesis, goddess of righteous retribution, and inscriptions and dedications there show the two goddesses worshipped jointly, Themis representing the lawful order that Nemesis existed to enforce against those who violated it. She also had a cult presence at Dodona, seat of one of Greece's oldest oracles of Zeus, reflecting the same association with prophecy and lawful order that marked her earlier role at Delphi, and further dedications and temples are attested for her at Athens and in the region of Phthiotis in Thessaly. This combination, an active oracular history predating Apollo's own famous shrine, plus standing altars and temples maintained into the historical period, sets Themis apart from primordial Titans like Oceanus or Tethys, who kept a purely mythological presence. Themis's worship reflects how directly her identity mattered to daily Greek civic life: courts, oaths and assemblies all invoked the concept of themis as lawful order, and the goddess who personified that concept was, unsurprisingly, one the Greeks actually prayed to.
