    Entheogens in Christian Art: Wasson, Allegro and the Psychedelic Gospels

    In light of new historical evidence regarding ethnomycologist R. Gordon Wasson’s correspondence with art historian Erwin Panofsky, this article provides an in-depth analysis of the presence of entheogenic mushroom images in Christian art within the context of the controversy between Wasson and philologist John Marco Allegro over the identification of a Garden of Eden fresco in the 12th century Chapel of Plaincourault in France. It reveals a compelling financial motive for Wasson’s refusal to acknowledge that this fresco represents Amanita muscaria, as well as for Wasson’s reluctance to pursue his hypothesis regarding the entheogenic origins of religion into Christian art and artifacts. While Wasson’s view – that the presence of psychoactive mushrooms in the Near and Middle East ended around 1000 BCE – prevailed and stymied research on entheogens in Christianity for decades, a new generation of 21st century researchers has documented growing evidence of A. muscaria and psilocybin-containing mushrooms in Christian art, consistent with ethnobotanist Giorgio Samorini’s typology of mushroom trees. This article presents original photographs, taken during fieldwork at churches and cathedrals throughout Europe and the Middle East, that confirm the presence of entheogenic mushrooms in Christian art: in frescoes, illuminated manuscripts, mosaics, sculptures, and stained glass windows. Based on this iconic evidence, the article proposes a psychedelic gospels theory and addresses critiques of this theory by art historians, ardent advocates, medieval historians, and conservative Catholics. It calls for the establishment of an Interdisciplinary Committee on the Psychedelic Gospels to independently evaluate the growing body of evidence of entheogenic mushrooms in Christian art in order to resolve a controversial question regarding the possible role of entheogens in the history and origins of Christianity

    Solid-state Isotopic Power Source for Computer Memory Chips

    Get PDF
    Recent developments in materials technology now make it possible to fabricate nonthermal thin-film radioisotopic energy converters (REC) with a specific power of 24 W/kg and a 10 year working life at 5 to 10 watts. This creates applications never before possible, such as placing the power supply directly on integrated circuit chips. The efficiency of the REC is about 25 percent which is two to three times greater than the 6 to 8 percent capabilities of current thermoelectric systems. Radio isotopic energy converters have the potential to meet many future space power requirements for a wide variety of applications with less mass, better efficiency, and less total area than other power conversion options. These benefits result in significant dollar savings over the projected mission lifetime

    Beam splitter employing birefringent optics provides either widely different or precisely equal beam ratios, it can be used with laser light source systems for interferometry of lossy media, holography, scattering measurements, and precise beam ratio applications

    Abundance and Identification of the Leafmining Guild on Apple in the Mid-Atlantic States

    Get PDF
    The leafmining guild on apple in the northeastern United States was studied from 1983 to 1988. Ten species of leafminers, all Lepidoptera, were encountered during the sampling. Phyllonorycter spp. (P. blancardella and P. crataegella) were the most ubiquitous and most abundant throughout the region. Lyonetia speculella was also abundant in both managed and unmanaged orchards, indicating a potential to become a pest. Bucculatrix pomiloliella and Coptodisca splendorilerella were abundant in unmanaged orchards, but were only rarely found in managed orchards. Coleophora serratella, Stigmella pomivorella, Parornix geminatella, Tischeria malifoliella, and Recurvaria nanella were also found. A key to the most important leafminer species on apple in the mid-Atlantic states, based on leafmine characteristics, is presented

    Stabilization of interferometer fringe patterns

    Get PDF
    Fringe pattern motion is compensated by closed-loop servo system that adjusts a mirror mounted on piezoelectric crystal, so that path difference in interferometer is maintained at constant values at one point in the field. System is applicable to holography with continuous wave laser sources
