Then (1978), The Road to Eleusis
The Immortality Key Extension: Brian Muraresku's 2020 Update
Wasson, Hofmann, and Ruck published in 1978, when the physical evidence for their hypothesis was limited to philological and ethnobotanical argument. They called for archaeological investigation, specifically chemical residue analysis of Eleusinian vessels, but the technology and funding for such analysis were not available.

Brian Muraresku's The Immortality Key (2020) extended the Road to Eleusis hypothesis to early Christianity and reached mass audiences (500,000+ copies). More significantly, Muraresku worked with Jordi Juan-Tresserras to commission the Mas Castellar de Pontós analysis (published 2020 in Antiquity and subsequent papers), the first physical evidence of ergot at a Demeter cult site. This confirmed what the Road to Eleusis hypothesis required was physically possible. Muraresku's Christianity extension, that early Christian eucharist drinks contained ergot alkaloids, received more skeptical treatment from classical scholars. The Eleusis-specific hypothesis has gained physical support; the early Christianity extension has not. The Road to Eleusis called for archaeology; archaeology has partially answered.
