Then (1978), The Road to Eleusis
The Chemistry Problem: Was Ergot Preparation Safe?
The primary scientific objection to the Road to Eleusis hypothesis was toxicological: ergot causes ergotism (gangrenous or convulsive poisoning) when consumed in contaminated grain. If the kykeon contained ergot, it would have poisoned the thousands of initiates who drank it annually. This was the objection that Wasson, Hofmann, and Ruck could not fully answer in 1978.
confirmed
Antonopoulos and colleagues (Scientific Reports, February 2026; Carl Ruck is a coauthor) tested the chemistry in the laboratory: lye (wood ash solution, universally available in antiquity as a cooking and processing agent) converts toxic ergot alkaloids (ergotamine, ergotoxine) into water-soluble lysergic acid amide derivatives at doses and temperatures achievable with ancient technology. The conversion is not merely theoretically possible, it was experimentally demonstrated. A kykeon prepared with lye-treated ergot-infected grain would be: free of toxic ergopeptides; containing water-soluble LSA derivatives; pharmacologically active at the concentrations achievable through standard ancient beverage preparation. The 1978 toxicity objection is answered.
