ABSTRACT
This paper discusses geometric proportions as a tool of design process, with specific focus on Islamic pattern design. The key role played by geometry in Islamic pattern is discussed in relation to proportions as an infra-structure to design process, in which evaluations based on spatial structure and aesthetic criteria are integrated into the conceptual phase of the design process. This serves two objectives; firstly, in pattern design proportions are strongly linked to geometry as a self-guiding method of aesthetically proved design. Secondly, geometric proportions regulate primarily the order of patterns, but at the same time it mediates between the two poles of order and diversity as well as between aesthetic levels.
This paper analyzes geometric principles and features of the design of traditional Islamic pattern, with regard to geometric proportion analysis and describes the syntheses of Islamic pattern from the Islamic cosmology, philosophy and metaphysical dimensions of geometry, finding that it followed a pre-established geometric and proportional design with high accuracy and great precision. Furthermore, the underlying relationship between cosmology and geometry is manifested in Islamic pattern where geometry acts as the vocabulary that structures the pattern language. These findings support the argument that geometry was independently discovered and used by Islamic culture as a universal language and constitutes one of the most important multicultural symbols in design.
