Sundial and double helix spiral

Time monument - sundial

A sundial has been on display in Wennigsen (Deister) for some time now. This timepiece was created by master precision engineer Erich Pollähne to mark his 80th birthday and his 25 years of work with sundials. All metal parts of the structure are made of stainless steel; the designs are etched and black-chromed, and the basalt stones are exceptionally durable. The sundial consists of a base plate featuring a cross-shaped cover. It depicts the stone engraving from Bornholm with the sixteen-part calendar of the Germanic peoples. The base plate is fitted with a stainless steel frame. This frame features 18 images from the history of timekeeping and astronomy up to the present day, including the moon landing and Neil Armstrong’s “small step.” The top plate of the sundial base features a view of the Earth with the southern hemisphere fanned out at its center. The Platonic cube (south face) displays the main clock. The horizontal clock is arranged on top of the cube (upper side). It shows the Babylonian and Italian hours. The equatorial clock, made of acrylic glass, stands parallel to the Earth’s axis, just like the south base of the cube. Here, it is possible to read both standard time and daylight saving time in CET.

Double helix - spiral of life

Long before our era, the single spiral was revered as a symbol of life. The new form, conceived as a double spiral by Hugo Kükelhaus, a craftsman-philosopher, is reminiscent of the DNA helix of our genetic makeup; however, it spirals in opposite directions. The unity of opposites is demonstrated; it has no beginning and no end. It symbolizes life, physical decay, but also resurrection or rebirth. Here in the town center, it stands for all of us. Take your time to follow the path of the spiral connections. Despite the traffic, a sense of calm will settle over you at this spot. The harmonious reversal of the coils reveals the eternal cycle. Ascent and descent occur in a single movement—the unity of opposites, even though every point on the spiral moves only in a single plane. The Wennigsen symbol at the tip of the spiral reveals another phenomenon. The crisscrossing of the symbol creates a pulsation through its stretching, representing breathing and a heartbeat. The elliptical shape alternates against the sky with the full circular disc. If you stand with your back to the sun and look at the disc, the cross-shaped symbol emits flashes of light corresponding to the fourfold number of turns of the spiral, which are themselves visible on the ground. There is no technical structure that combines as much meaning and significance as the engraved field disc.
