Ghost Tree
Christoph Rihs' work 'Ghost Tree' explores nature as an ephemeral phenomenon, made newly visible and tangible through art.
The Ghost Tree – III hovers just above the ground in a small forest clearing within the Wartegg Castle park, nestled among smaller and larger trees.
The sculpture consists of a slender, upward-tapering truncated cone, its outer skin crafted from geotextile. From this material, leaf contours and veins of ivy leaves and tendrils are cut out, reminiscent of a trunk entwined with ivy. The light grey polypropylene fleece is translucent, revealing individual fibres and giving the shell the appearance of Japanese paper.
The cut-outs create a mashrabiyya-like semi-transparency, allowing both glimpses into the interior and views of the surroundings. The form is supported by sewn-in iron rings, which give the sculpture a uniform curvature.
The entire structure hangs from wire ropes, anchored to the forks of surrounding trees. The weight of the rings tightens the geotextile shell and accentuates its characteristic, tapering silhouette. Despite its size and volume, the transparency and material structure create the impression of a light, floating form that subtly moves with the wind.
Particularly fascinating is the dynamic interplay of light and shadow: At certain times of day, the surrounding trees cast their shadows onto the translucent outer skin of the Ghost Tree. This creates a deceptively real illusion, as if the cast shadows themselves were the trunk and foliage of the sculpture, organically merging with the natural surroundings.
