This book studies the principles of urban spatial organization of historic cities. It can be considered a guide to design, presenting qualitative criteria to satisfy practical needs. The subject is explored through interconnected chapters, each addressing an important aspect of form-space and design values, knowledge and our present problems.   In this book the interpretation is artistic and socio-cultural. Discussion is not concentrated on singular urban space but on interrelated spaces and elements across the city, and complexes. Considering the comparative aspects of study, the reader will notice that despite cultural differences, there is a common understanding in artistic creativity and sensibility in the presented examples.
