"Let me preserve a discreet silence, too, concerning that rite of Demeter which the Greeks call Thesmophoria, except as much of it as I am not forbidden to mention. The daughters of Danaus were those who brought this rite out of Egypt and taught it to the Pelasgian women; afterwards, when the people of the Peloponnese were driven out by the Dorians, it was lost, except in so far as it was preserved by the Arcadians, the Peloponnesian people which was not driven out but left in its home."

- HERODOTOS, THE HISTORIES  2.171

----------------------------

Mysterious and misunderstood, the Thesmophoria festivals of Demeter and Kore (Persephone) prohibited the presence of men and featured distinctively perplexing elements: piglets in pits, ritual swearing, pomegranate seeds and contraceptive plants, frenzied dancing.

What happened during the Thesmophoria has been historically dismissed as "mere" fertility ritual or even a tool of control, reinforcing a woman's role as wife and mother for the patriarchy. Yet the very name Thesmophoria seems to hint at a mystery beyond agricultural concerns or societal expectations -- meaning literally,
The Carrying of the Holy Law / Divine Order.
And then there is the seemingly-unrelated name of the priestesses who performed these mysteries: Μέλισσαι, Melissai -- Bees (Apollodorus, FGrH 244 F89). 

These enigmatic rites of Demeter and Kore were supported financially by husbands and faithfully performed year after year by wives in at least 30 cities across Greece, Southern Italy, and Anatolia. The Ancient Greeks themselves believed the rites to be very ancient, perhaps more ancient than the Eleusinian Mysteries. Their wide diffusion points to an existence at least as early as the late Bronze Age, hundreds of years before the advent of the polis and its great marble and limestone temples.

What happened in the Thesmophoria was not merely symbolic reenactment. It was a carefully-preserved tradition of ritual magic from holy women of prehistoric times. It was a magic which infused the soil with steady sustenance and called down the rain nymphs to weep upon Gaia, an elemental magic which could only be wielded by devotees sitting side by side in seclusion. It was a magic of sexual power, of political power, of economic power. It was understood as the tending of a neglected cosmic hive then -- thousands of years later, it is needed more than ever.

This summer coinciding with Metageitnion, Boedromion, and Pyanopsion, sacred mystery months of Demeter and Kore in Attika, we will step inside the mystery as new Thesmophoric Melissai -- Bees who Carry the Holy Law of the Mother and Daughter, Bringers of the Divine Order.

WE WILL EXPLORE...

  • Prehistoric origins of the goddesses Demeter and Kore, along with theorised origins of the Thesmophoria
  • Lore and traditions of Melissai Priestesses of Demeter and Kore across the ancient world, including trance and entheogenic mysteries
  • Ancient understandings of magic, and the blurred line between magic and ritual in Ancient Hellenic Religion
  • In depth-analysis of each of the four stages of the Attic Thesmophoria rites, and the authentic ways we can perform them today
  • Ritual scripts for related festivals of Demeter and Kore leading up to the Thesmophoria along with step-by-step instruction for the Thesmophoria

This training draws upon secondary scholarship and Bria's own dissertation research which examines prehistoric & ancient sources such as poetry, comedic plays, epigraphy, art and material culture. Building upon the wisdom of previous approaches, she unveils a new layer of the Thesmophoria through sympathetic magic theories and considerations of ritual object materiality / the exerted influence of ritual items, words, dress, space, food, and dromena ("things done", such as trance dances and mythic reenactment).

At the end of the 10 weeks culminating in the Thesmophoria in October, participants may choose to be consecrated as Thesmophoric Melissai. This will involve a 4-day ritual process, a final ceremony online, a vow of commitment and silence (about the Mysteries), invited participation in Mt Nysa's Thesmophorion (ongoing community of Melissai dedicated to carrying on the Thesmophoric rites of Demeter and Kore), and the opportunity for election as an Archousa (Liturgical Leader).

In respect of the ancestral tradition, this training is only for femme-identifying individuals above the age of 18. While biological fertility is an important dimension of the Thesmophoria, it does not seem a requisite of its priestesses; for instance, post-childbearing women were vital to the Mysteries of Demeter and Kore. Thus it is reasonable for modern adaptations of the rites to reflect our more fluid understandings of gender. Please be advised there will be discussions of sexual organs, sexuality, animal sacrifice, and entheogens (psychoactive substances); we ask you to use discernment if these topics may be uncomfortable for you.

student testimonials

Mt Nysa and the Thesmophoric Magic course has done a lot in my life. It gave me a new found drive and passionate motivation to be more of a academic based leader in my community. I truly feel the ability to be a Melissa and elected Archousa has changed me for the better spiritually and in the mundane. This course gave me a large jumping point that cascaded my practice into an evolved state. I am grateful for this course as well as this community that was fostered by it. Having a space to learn about mysteries and not feel judged is wonderful and truly needed in this community. It has been amazing experience and still is. -- XANDRA


As a return student to Mt Nysa, I can say with confidence that every class taught is full of wonderful information. The Melissai Training course is no exception to this. I feel that through this course I gained foundational knowledge of the Thesmophoria, its mysteries, history and a deepened connection with Demeter and Kore. I can’t recommend this course enough! If the great goddesses are calling, this is the course for you. -- MINERVA
