“Themis’s themes are justice, equity, reason, morality, organization, foresight, karma and truth. Her symbols are balanced items and scales. In Greek tradition, Themis personifies the law in both spirit and deed. She regulates karmic order in the cosmos and presides over matters of moral judgment. Today, Themis strengthens the voice of consciousness and the gift of foresight within us, becoming a sound counsellor in difficult decisions and offering balanced perspectives.
Bearing in mind Themis’s legal theme, tend to any pressing legal matters today. If a court matter is pending, check on it. If you need to catch up on past-due parking tickets, do so. Themis will help resolve any matter of law in the most equitable manner possible.
Should you actually have to go to court today, carry an image of a scale or any balanced geometric figure in your pocket to invite Her assistance. Themis lives in just actions and orderliness, so just by treating people fairly and organizing your day, you invoke Her presence.
Throughout the day, take an extra moment to consider the repercussions of your actions, both mundanely and spiritually. Consider this a time to balance your karmic check book and make right some wrongs in your life. Also, be honest in your words and thoughts today. This honors and pleases this Goddess greatly.”
(Patricia Telesco, “365 Goddess: a daily guide to the magic and inspiration of the goddess”.)
The ‘steadfast one,’ the daughter of Gaia, was the earth Goddess personified as an unshakable power. By Homer‘s time, She had come to signify a second powerful steadfastness: the social contract among people living on the earth (similarly Fides). One of the most ancient and most hallowed of Goddesses, Themis later became a vague and abstract personality. Yet evidence of Her original precedence is suggested: no Olympian gathering could take palace unless She called it, and neither could any divinity lift the cup of nectar before She had drunk.
In the language of Her people, themis was a common as well as a proper noun, the former indicating the power of convention, of whatever is fixed in society as steadfastly as the earth beneath us. The personification of such social cohesion, Themis was shown bearing a pair of scales; as the fruitful earth, She was shown holding the cornucopia. She was mother of the seasons, or Horae, Goddesses who determined the proper moment for the fruitful earth’s budding and exhaustion, and the proper times as well for human events. One of Themis’ daughters, the fierce Dike, was Her own maiden self, a stern, uncompromising virgin.
Themis ruled prophesy, for She knew human nature and the nature of human society and so could predict the outcome of any struggle; thus She shared with Mother Gaia the famous Delphic Oracle. For Her worship, She demanded group dancing, the symbol of group’s bonding through graceful action. Eldest of Greek Goddesses, She was the first to whom temples were built, for before Her there was no human community to offer worship” (Monaghan, p. 294 – 295).
“The only consort for Themis mentioned in the sources below is Zeus.
A Roman equivalent of one aspect of Hellenic Themis, as the personification of the divine rightness of law, was Iustitia (Anglicized as Justitia). Her origins are in civic abstractions of a Roman mindset, rather than archaic mythology, so drawing comparisons is not fruitful. [Themis is] portrayed as an impassive woman, holding scales and a double-edged sword (sometimes a cornucopia), and since the 16th century usually shown blindfolded.”
