The Place of Sacred Geometry in Identification of Iran Traditional Architecture

The concept of identity encompasses a variety of elements and categories, and traditional arts have always been one of the identification bases of Iran's identity. Traditional architecture as the most sensible and perceivable part of Iranian art, have emerged in constructing elements and various physical structures that have been effective as identifying elements on Iranian architecture's soul of position. One of these elements emerges in the form of sacred geometry. Sacred geometry, as the highest model of symbolic material forms, appears in the structure of traditional architecture in a best way, and influences on the architecture identity. Now the question arises that, what is the role of geometric decoration in identity-making of Iranian traditional architecture in Islamic era? And what concepts and forms are the factors of architecture identity making in sacred geometry? This research has been performed by analytical-descriptive method in order to present a model for drawing the relationship between sacred geometry and components of its identity. Finally, the result was that the presence of geometric shapes in traditional decoration is like a metaphorical language that gives specific place aesthetic experience to the man. The "sameness" achieved by this experience, is the predisposition of significant meaningful identity for traditional architecture. It means that the consistency of sacred geometry with human identity leads to the continuation of the relationship between human and place; the place that its identity is consistent with human, in the way that the operational, semantic and physical characteristics of the sacred geometry will carry messages that give meaning to the traditional architectural identity.
