The Eleusinian Mysteries honored Demeter and Persephone with annual initiations involving a sacred drink called kykeon. A 2026 experiment showed that treating ergot in lye for 2 hours removed toxic ergopeptides while preserving psychoactive LSA compounds. Critics Shardai Mejia and Richard Ascough caution chemical feasibility isn't historical proof — no Eleusis vessel has yielded ergot residue.

Key facts
- The Eleusinian Mysteries were annual initiations at Eleusis near Athens honoring Demeter and Persephone, involving a sacred drink called kykeon.

- No vessel from Eleusis has yielded ergot residue, and no ancient recipe survives.
- Ergot appeared in a ritual context at Mas Castellar de Pontós sanctuary in Spain, associated with a cave sacred to a mother goddess.
