verification note: The primary chapters have NOT been obtained. The exact chapter citations above are transcribed from the reference list of Antonopoulos et al. 2026 (refs. 23–24), read in full on 2026-08-25. Everything this case says about the find is therefore secondhand; obtaining and re-verifying the primary publication is research item TIK-R004, and the record is labeled unverified until then.
reliability notes: The single archaeological hinge of the Eleusinian case: reported ergot in a ceremonial vessel and in human dental calculus at a Demeter/Kore-linked site.
A 2002 analysis never independently replicated; note the documented source-drift risk — 'fragments of ergot identified' has been converted downstream into 'hallucinogenic alkaloids detected,' which the primary wording (as quoted by the 2026 paper) does not state.

what the source states: As summarized (with primary citations) by Antonopoulos et al. 2026: at Mas Castellar de Pontós, near the ancient Greek colony of Emporion, inside a sanctuary dedicated to the two Eleusinian Goddesses, archaeologists discovered fragments of ergot both inside a ceremonial vase and in the dental calculus of a 25-year-old man, providing evidence of its consumption (Juan-Tresserras 2002).
what we infer: The one datum combining substance, ingestion evidence, and cultic context — much closer to the hypothesis than generic ancient drug use, and still a thousand kilometers from Eleusis. Note the source-drift hazard this record exists to freeze: the primary-level claim is identified ergot microremains; "hallucinogenic alkaloids chemically detected" is a downstream hardening the record does not support.
limitations: Single 2002 analysis, never independently replicated; this case has so far seen the primary publication only through the 2026 paper's citations (TIK-R004 is the retrieval and re-analysis item).
Iberia, not Attica: evidence that an ergot-associated practice could exist in one Demeter/Kore-related setting, not that it was the recipe at the mother sanctuary — analogy, not identity.
