My pleasure!
I’m glad I found that link, I thought that documentary had been removed from online. I picked it up on DVD, uh, a long while back, it’s mostly excellent, although the segments seem too short.
I just realized I omitted this topic from the weekly GGG digest I sent an hour or so ago. I’ll note that next week.
"The Eleusinian Mysteries were initiations held every year for the cult of Demeter and Persephone based at the Panhellenic Sanctuary of Eleusis in ancient Greece.0 They were celebrated annually for at least a thousand years until 329 CE. The festival started in early September in Eleusis, a town 14 miles from Athens, and was known as the most mysterious of the ancient Greek world.2 According to the myth told in the Homeric Hymn to Demeter, the earth goddess Demeter went to Eleusis in search of her daughter Kore (Persephone), who had been abducted by Hades (Pluto). The Eleusinian Mysteries are considered the most famous of the secret religious rites of ancient Greece."

"Ergotism was likely discovered when humans began cultivating grain, about 10,000 years ago. Roman scholar Pliny is the first to mention ergot-infested grain much later, in the first century AD, but not until after historians and chemists described the Greeks using the fungus as a chemical weapon and a psychoactive drug during the celebrations of the Eleusinian Mysteries."
