This is a mistake, because although the forms that has remained more or less the same their meaning has shifted dramatically over the 5th century BC is vastly different from what it meant in the 3rd century AD, and different again in the 16th century. We always see buildings against a background of buildings that we have seen before, and this influences what it is that we feel about the buildings. The forms of the buildings might remain more or less the same, but we would see them as different architecture from age to age, from culture to culture, and even perhaps from person to person, depending on what our experiences have been, and what it is that we know.
