article on Clebsch and Klein in the family room for more information on that very special occasion. The version we present here consists of its 27 lines only.lfred Clebsch (1833-1872) presented his nowadays quite famous model of a diagonal surface in 1872 at Göttingen during a meeting – see our
One of the main features of Clebsch’s diagonal surface model is the fact that it was the first model of a cubic surface which had all its 27 straight lines real and nicely situated on the object. It was known since 1849 that any smooth cubic surface contains exactly 27 straight lines – but possibly imaginary! Earlier attempts by others failed to produce such a beautiful model of a cubic with its 27 lines. Either not all lines were real or all were real, but some of the lines where either too close together or too far apart to be easily distinguishable. Or – in the case of Wiener’s model – the model was not symmetric and did thus not allow to easily understand the interesting intersection properties of the lines. In the early 1880s, a model of Clebsch’s diagonal surface became part of Rodenberg’s series of 26 cubic surface models.
As you can see from the photo, the lines are designed a little thicker than the thin surface part, but the thin surface part also contains a small border curve which is exactly as thick as the lines. As one can see, the sculpture is quite fragile in order to focus on the structure of the lines.

It was back in the 1872 Göttingen, Germany, at a meeting of the scientific society. Alfred Clebsch and Felix Klein each presented a model of a cubic surface. Our modern versions of these historical - nowadays quite famous - sculptures are the main figures in our photo.
