A complex web of documentary and fiction forms the core of the photo series, installations and films realized by Joachim Koester. After careful consideration, the artist selects from a diverse range of sources paying special attention to the mystery surrounding missing fragments and ambiguities present in our history. In doing so his work reveals a common link, sparked by his personal interests: the discovery of unknown regions, the human body, body language and performance; art, history and art history; the occult (or the secret doctrine of the unknown), the hidden or the immeasurable; the limits of the human mind and experiments for its expansion. Exploring the threshold of the esoteric is a constant theme in his oeuvre.
