The marble sculpture PROMETHEUS DELIVERED – a replica of Prometheus Bound by Nicolas Sébastien Adam (1762) – is slowly decomposed by chemolithoautotrophic bacteria. The acidic process water from the bioreactor KAZBEK penetrates the body of the sculpture via tubes and runs off the surface of the stone. The limestone turns into gypsum while the sculpture slowly dissolves. The biomass of the bacteria is the energy source for human liver cells from which the organic sculpture OCTOPLASMA grows. Inorganic stone turns into organic meat. PROMETHEUS DELIVERED is a play on words, referring to birth in the sense of “delivery”, and to the central importance of the liver in myth.
