St Anthony's Fire and the Sun Door

It is through this Sun Door circle of wheat that the heavens were said to open up. The reason it was made from wheat is most likely due to the entheogenic effects of a fungus called ergot that grew on the wheat.

Ergot is believed to have been used in the kykeon, an entheogenic tea, during the Eleusinian Mysteries. The ingestion of the kykeon was a component of the famous ceremony at Eleusis, performed for nearly two thousand consecutive years to worship Demeter, the Goddess of grain and fertility. Initiates at Eleusis included Socrates, Plato, and many other great names of Greek antiquity.

The Eleusinian Mysteries were composed of the Greater and Lesser Mysteries. Initiates at Eleusis would go through the Lesser Mysteries first, then they would experience the Greater Mysteries. Ergot is believed to be the active ingredient that was part of the Greater Mysteries, while psilocybin mushrooms are believed to be the active ingredient that was part of the Lesser Mysteries.

An overdose of ergot was known as "St Anthony's Fire." It was Albert Hoffman who discovered ergotamine could be used to synthesize LSD while searching for a cure for migraines.
