Architecture can be regarded as the container in which human being lives his life and it is impossible to think of human life out of its container. The history of architecture is in fact the history of that container. All the historical texts on various aspects of human life can be regarded as the potential source of inquiry about the history of architecture. Persian literature being the most prominent expression of Persian culture over the course of history offers a potentially plentiful source for the investigation about the history of Persian architecture. This study tries to trace and extract any relevant information about Persian architecture within all Persian prose texts written over the course of the early Islamic era from the emergence of Dari language up until the mid fifth century AH (eleventh century AD). The author tried to collect, organize and interpret all the explicit or implicit information from those texts that are related to buildings and their characteristics, cities and urban life, founder of cities, architects, artisans, craftsmen and their patrons, construction projects, materials and instruments as well as architectural archetypes, myths, concepts and esthetic tastes and finally the architectural terminology. Along this he tried to conceptualize a search method aiming at such investigation on historical Persian texts. The data base of what is found in the texts (in a compact disc) is included in the volume.
