For the representation of the Tempietto del Bramante it had to be considered that originally a circular courtyard surrounded by columns was planned, whereas the courtyard today is square and without surrounding columns. Steps also originally led to the temple, so that the observer could see the building from below. Grimm designed the pedestal historically correct as a circular surface and made it so high that the underside of the building, mediated by the steps of the temple, became visible. In the reconstruction of ancient temples such as the Pantheon or Parthenon, fundamental decisions had to be made as to which phase of the respective building should be represented – the ideal state or an image of what the temples look like today. Finally, a scale had to be chosen that illustrates the essential elements of the architecture without getting lost in details.
