      abstract     = {Since the beginning of a theoretical occupation with the
                      »city« there is a large uncertainty in defining what urban
                      form is and what it eventually consists of. As a matter of
                      fact, we somewhat instinctively attribute morphologically
                      completely diverse urban entities with this term,
                      notwithstanding their often utterly unlike topographic
                      settings or cultural backgrounds. Moreover, we do so not
                      only with properly existing entities, but expand our »idea
                      of the city« also over the past. And yet, until today we do
                      not find considerable comprehensive definitions for the
                      »city«, which cover all its aspects. Moreover, the growing
                      uncertainty of how to plan and design cities today
                      eventually aggravates the assignment. Yet, despite the
                      definitory quandary, our »idea of the city« is seemingly
                      settled on a commonsensical formal conception than on
                      scientifically verifiable functional features: We recognize
                      cities by taking a look at their layout from an airplane
                      window or by approaching a city's skyline in a vehicle. We
                      perceive urban space by strolling through its streets and
                      places, or even by visiting deserted archaeological sites of
                      long gone civilizations. For this perception, arguably, the
                      sheer formal appearance is sufficient, to which we then of
                      course add functional relations according to our
                      contemporary understanding of urban life. Ultimately, one
                      might speak of a »formal urban continuum« that for us
                      exists since the Bronze Age and carries on until today and
                      which without further thought is inscribed in our common
                      knowledge as reference for any urban entity we encounter.
                      The aim of the proposed presentation is to suggest an
                      approach towards this formal urban continuum, by examining
                      its phenomenological condition and by investigating for its
                      possible parameters, whose systemic interrelation might, in
                      spite of the common formal idea, eventually explain the
                      grand diversity of cities.},
