Planetare Allianz

In expansive compositions in light, Susanne Rottenbacher (b. Göttingen, 1969; lives and works in Berlin) visualizes the fire of life in its timebound and fluid dimension. Plotinus called fire the “spiritual potency of beauty.” Pursuing a similar vision, Rottenbacher’s works orchestrate light as energy in space. To this end, the artist, who studied light and stage design in the United States and the United Kingdom, creates weightless luminous choreographies realized in colorful LED technology in combination with acrylic glass as a translucent vehicle of form. The results are installations in three dimensions that are deeply silent yet unfold in a magical ecstasy of light.

In Christian sacred architecture, light has been deployed and perceived since the Middle Ages as the aesthetic equivalent of the divine mind’s lucidity. The history of light art, by contrast, is much younger, going back to the years after the First World War. Having built her creative practice over the past fifteen years, Rottenbacher not only continues a century-old tradition of light art in Europe and the U.S.; her works also anticipate a future in which humanity will have room for feelings no less than for scientific knowledge.

The Political Substance of Wood

Jems Koko Bi (b. Sinfra, Côte d’Ivoire, 1966; lives and works in Kaarst, Germany, Dakar, and Abidjan) is world-renowned for the monumental wood sculptures he creates using a machine saw. This book juxtaposes his most recent body of works with the large-format woodcuts of HAP Grieshaber (b. Rot an der Rot, Germany, 1909; d. Eningen unter Achalm, 1981). Although the two artists never met, their oeuvres are characterized by similar themes, values, and materials. The central concern is the fate of the forests and its momentous political and social implications: Grieshaber’s woodcuts articulate his principled opposition to the predatory exploitation of nature in the 1970s—an issue that is more relevant than ever today in light of the climate crisis and the Fridays for Future movement. Koko Bi’s figural groups bring this tradition of political art into our time, making a global and universally compelling case for a sustainable husbandry of our resources.

Jems Koko Bi studied at the Institut National Supérieur des Arts et de l’Action Culturelle (INSAAC), Abidjan, and the Düsseldorf Academy of Fine Arts. His work has been exhibited widely, including at the Centre Pompidou, Paris; at documenta 13; the Havana Biennial; and several Venice Biennials and Dakar Biennials. In 2019, he founded the forest biennial Abidjan Green Arts.

HAP Grieshaber studied advertising art at the Staatliche Kunstgewerbeschule, Stuttgart. His work is regarded as a signal contribution to the renewal of the woodcut medium in the twentieth century. He participated in documentas I, II, and III, held a professorship at the State Academy of Fine Arts Karlsruhe, and was honored with numerous awards and retrospectives.
