Carsten Höller (*1961 in Brussels) traces the myth of soma, a healing drink made by Vedic nomads in northern India during the 2nd century BCE. It promised knowledge, immortality, and access to the divine sphere. The exact psychoactive contents of this drink are not known for certain. One of the substances favored by researchers is the fly agaric, a common, poisonous mushroom. This publication focuses on a collection of written research on soma; the sources date from the early eighteenth century to the present day, and represent a variety of scientific disciplines and approaches. Soma, then, is the subject of the excerpted material that serves as the basis for Höller’s artistic work, while at the same time, the material inquires into the exactitude of scientific knowledge.
