The most difficult parts of this reconstruction are — without any detailed

elaborated capitals. Besides the aspect that nearly no column by the 
base without damages is available, additionally the fact has to architec 
be taken into account that the columns could not be acquired by achieve 
photo-grammetry from all directions due to spatial restrictions. arcs. À 
In contrast to the architrave the bases consist of a lot of curved planes,

can be obtained by combination of different circular discs, done, «

The flutes were constructed by a horizontal contour line 
extracted from photogrammetric measurements. A vertical 
displacement leads to a volumetric description of the column

Each storey has its own type of columns and capitals (Figure 9 Figure 11. Reconstructed capital (type of upper storey) 
and 10). For each type of capital a special generalised model 
was constructed. Both are strongly abstracted by a basic shape
