1. Introduction

The use of psychoactive mushrooms, particularly in religious and ceremonial contexts, has a deep-rooted history that stretches back thousands of years. Evidence from Mesoamerica, Europe, and Africa points to the integral role that hallucinogenic fungi played in rituals aimed at invoking spiritual experiences or connecting with divine entities. Through the centuries, these practices were shaped by cultural exchange, colonization, and scientific exploration, laying the foundation for the modern study and understanding of entheogens.

2. The Origins of Mushroom Use in Religious Ceremonies

2.1. Mesoamerican Rituals: 3000 Years of Tradition

In Mesoamerica, psychoactive mushrooms have been used for ceremonial and religious purposes for over 3,000 years. Ancient cultures in the region, including the Maya and the Aztecs, consumed these mushrooms during rituals that aimed to communicate with deities or enter altered states of consciousness. These rituals were often deeply intertwined with their spiritual beliefs, making mushrooms a significant element in their religious practices.

2.2. Saharan Rock Art: Evidence from 9000–7000 BCE

One of the oldest pieces of evidence of human interaction with psychoactive mushrooms comes from the Sahara Desert. In southeastern Algeria, murals dating from 9000 to 7000 BCE were discovered, depicting horned figures resembling dancers holding mushroom-like objects. These images suggest that psychoactive mushrooms might have been used in early religious ceremonies, potentially symbolizing a link between the human and the spiritual worlds.

2.3. Pictographs from Spain: Evidence of Psilocybe Use

In the region near Villar del Humo, Spain, 6,000-year-old rock paintings were uncovered, illustrating several mushroom-like forms. Researchers have tentatively identified these as Psilocybe hispanica, a species of hallucinogenic mushrooms native to the area. This suggests that the use of psychoactive fungi was not limited to Mesoamerica, but may have had a broader presence in prehistoric European cultures as well.

3. Mushroom Ceremonies in Mesoamerican Civilizations

3.1. The Aztec Connection: Teonanácatl, "God's Flesh"

In the Aztec civilization, psychoactive mushrooms were highly revered, known as teonanácatl, which translates to "God's flesh" in the Nahuatl language. These mushrooms were considered sacred and were consumed during religious ceremonies to foster a connection with the divine. Chroniclers from the 16th century report that mushrooms were used in grand celebrations, such as the accession of emperors or the successful completion of trade expeditions.

3.2. Spanish Conquest and the Suppression of Entheogens

The arrival of Spanish explorers in the 16th century marked a turning point in the use of psychoactive mushrooms in Mesoamerica. Spanish chroniclers recorded the ritual use of mushrooms by indigenous peoples, noting their role in religious festivals and ceremonies. However, after the Spanish conquered the Aztec Empire, they sought to eliminate practices that they considered to be "pagan idolatry." As a result, the ceremonial use of mushrooms was outlawed, and for the next four centuries, native populations were forced to hide their entheogenic practices from colonial authorities.

4. Revival of Interest in Psychoactive Mushrooms

4.1. R. Gordon Wasson’s Groundbreaking Research

The modern world’s rediscovery of the ceremonial use of psychoactive mushrooms began with R. Gordon Wasson, an American banker and amateur ethnomycologist. In the 1950s, Wasson visited a Mazatec village in Mexico, where he participated in a traditional mushroom ceremony. His article, "Seeking the Magic Mushroom," published in Life magazine in 1957, introduced the Western world to the use of mushrooms as sacred tools for spiritual exploration.

4.2. Roger Heim and the Scientific Classification of Psilocybes

Following Wasson’s pioneering research, French mycologist Roger Heim accompanied him on a second expedition to Mexico. Heim’s role was crucial in identifying and classifying the mushrooms that were used in Mazatec rituals. His research confirmed that several of the species involved were from the Psilocybe genus, which includes many of the most well-known psychoactive mushrooms.

4.3. Albert Hofmann’s Discovery of Psychoactive Compounds

The scientific exploration of psychoactive mushrooms reached a new height when Roger Heim sent samples of the mushrooms to Swiss chemist Albert Hofmann. Hofmann, best known for his discovery of LSD in 1938, was employed by the pharmaceutical company Sandoz (now Novartis). His research team successfully isolated and identified the psychoactive compounds present in Psilocybe mexicana, further establishing the scientific basis for the mushrooms' mind-altering properties. Hofmann’s work helped bridge the gap between traditional indigenous knowledge and modern pharmacology.
