چکیده
پژوهش پیشِ رو، با هدف تحلیل نظام زیبایی شناختی کاشی های ستاره ای شکل زرین فام (نمونه ای ممتاز از هنر ایرانی اسلامی) و بر پایه آراء ابن هیثم انجام شده است. نظریه ادراک زیبایی ابن هیثم، به عنوان یکی از جامع ترین مبانی زیبایی شناسی، قابلیت تطبیق با آثار هنر اسلامی را داراست. پرسش اصلی آن است که الگوهای طراحی در کاشی های ستاره ای شکل چگونه بازتابی از فرایند ادراک زیبایی در نظریه ابن هیثم (شامل مراحل مشاهده گری نظام مند، تحلیل عقلانی و همنشینی معانی جزئیه) هستند؟ یافته های تحقیق در دو بخش حاصل شده است: اول؛ تطابق معانی جزئیه در نظریه ابن هیثم (مبتنی بر مشاهده گری نظام مند و تحلیل عقلانی) با الگوهای طراحی کاشی های ستاره ای شکل که شامل این موارد است: کاربرد دقیق زیرنقش های هندسی در ترکیب بندی آثار؛ و نیز، شیوه بازنمایی سوژه ها. و دوم؛ مطالعه فرایند نقش پردازی که بیان گر آن است که بر پایه مراحل ادراک ابن هیثم، هنرمند مراحل گزینش و چینش عناصر را ابتدا مشاهده، سپس تأمل و سرانجام استنتاج می کند. نتیجه آن که زیبایی در کاشی های ستاره ای شکل، صرفاً نتیجه مهارت فنی نیست، بلکه بازتابی از فرایند ادراک نظام مند است که به خوبی بازتابی است از آراء ابن هیثم در باب زیبایی شناسی. دو دستاورد کلیدی این تحقیق عبارتند از: 1. وحدت بصری در کاشی ها، حاصل تعامل میان «معانی جزئیه» (جزءنگرایی هدفمند) و «کلان نگری هندسی» است که انسجام فرمال را تقویت می کند. 2. همخوانی میان مبانی نظری ابن هیثم و شیوه اجرای آثار، گویای پیوند عمیق هنر اسلامی با دانش تجربی است؛ پیوندی که در آن، زیبایی نه به مثابه امری ذوقی، بلکه به عنوان فرایندی عقلانی-حسی تعریف می شود.Aesthetic Reading of Star-Shaped Tiles (6th-8th Century AH) Based on the Principles of Visual Perception by Ibn al-Haytham
Tile art in the 6th century AH, characterized by the evolution of lusterware techniques and the development of complex geometric pattern-making methods, reached one of the most brilliant periods in Islamic art. During this era, Iranian artists created a distinctive style through the invention and use of star compositions and multi-petalled crosses, designed with mathematical precision within intricate geometric networks. A notable feature of these tiles is the detailed illustration of literary stories, executed with meticulous attention to detail. This style not only adorned mosques and tombs but also symbolized the connection between art, science, and mysticism in Islamic civilization. However, despite extensive technical studies on the materials and methods used to produce luster tiles, the theoretical foundations governing the aesthetics of these works—particularly in terms of design and visual perception—have been less thoroughly analyzed within the context of the scientific knowledge of that era. This gap calls for a re-examination of luster tiles through the lens of scholars such as Hasan Ibn al-Haytham (354–430 AH).In his “Book of Optics,” one of the earliest systematic texts on visual perception, he explains the process of seeing and perceiving beauty based on empirical and mathematical principles. In this book, Ibn al-Haytham proposes twenty-two fundamental principles: 1) Light (brightness), 2) Dark (dimness), 3) Color, 4) Dimension or distance (far or closeness), 5) Status or Place (spatial direction), 6) Embodiment (physicality), 7) Shape, 8) Magnitude (size), 9) Distraction (dispersion), 10) Connection (continuity), 11) Number, 12) Movement, 13) Immobility, 14) Softness (smoothness), 15) Roughness (unevenness), 16) Transparency, 17) Turbidity, 18) Shadowing, 19) Beautifulness, 20) Ugliness, 21) Similarity (homogeneity), and 22) Dissimilarity (heterogeneity.) These principles, coherently and with an emphasis on “systematic observation,” “rational analysis of phenomena,” and “integrating details into a harmonious whole,” provide a novel framework for understanding beauty. Ibn al-Haytham delineates hierarchical stages in the process of perceiving beauty. These stages start with the identification of visual qualities and, through analogy, assessment, and perception, culminate in perceiving the highest form of beauty. According to his theory, perceptual knowledge is acquired through three avenues: 1) sense alone, 2) prior knowledge, and 3) analogy and rational inquiry—the latter is the primary path to understanding beauty. Notably, Ibn al-Haytham asserts that perceiving all twenty-two visual qualities is not necessary; even a single quality—such as light or luminescence—can evoke beauty. In the context of the star tiles, light and luminosity alone can generate a sense of beauty. However, in their illustration style, there are also characteristics that can be aligned with Ibn al-Haytham’s detailed meanings and the visual concepts derived from them. Based on this understanding, the present study aims to address the fundamental question: How do the design patterns of star-shaped tiles reflect the process of beauty perception according to Ibn al-Haytham’s theory (including the stages of systematic observation, rational analysis, and the association of particular meanings)? This research was conducted using a qualitative approach and a descriptive-analytical method. Data were collected through documentary research and a review of library resources, including specialized texts on Islamic art, scientific articles, and historical documents. Samples were purposefully selected from star tiles preserved in museum collections. To enhance robustness, the data analysis was carried out in two stages: Identification of visual features: Examining design elements such as motifs, visual patterns, and composition, and comparing them with the principles outlined in Ibn al-Haytham’s “Book of Optics.” Theoretical adaptation: Extracting key concepts from Ibn al-Haytham’s theory—such as "systematic observation," "rational analysis," and "particular meanings"—and assessing their consistency with observed visual patterns in the tiles.The study employs an interpretive reasoning approach to analyze the relationship between the theoretical principles and the artistic practices, ensuring validity through triangulation—comparing literary sources, visual examples, and the overarching theoretical framework.The findings are presented in two main sections. First, the alignment of “particular meanings” in Ibn al-Haytham’s theory—based on systematic observation and rational analysis—with the design patterns of star-shaped tiles, including the precise application of geometric sub-patterns in composition and the method of depicting subjects within the star-shaped frames. Second, insights into the design process itself, which indicate that, in accordance with Ibn al-Haytham’s stages of perception, the artist first observes, then contemplates, and finally infers the selection and arrangement of elements. Building on these insights, five key patterns—variety, rhythm, scale, unity, and harmony—are analyzed within the visual structure of star-shaped tiles as follows: Consistency of “Particular Meanings” with Tile Design: Ibn al-Haytham’s “particular meanings”—such as movement, similarity, difference, dispersion, distance, farness, and nearness—are reflected in the tile designs, especially through geometric sub-patterns and mathematical compositions. Artists, by emphasizing core characteristics and eliminating superfluous details, achieved a form of “visual unity” resulting from the calculated juxtaposition of elements within the frame. This formal characteristic accentuates the independence of the star-shaped frame, which functions as a self-contained visual world. The placement of pictorial elements adheres to systematic rules—such as diagonal arrangements—which create directional tension and dynamic balance. Perception as a Rational-Sensory Process: Considering Ibn al-Haytham’s emphasis on reason in aesthetic perception, the organization of fundamental elements within the star framework produces complex structures. Reflective analysis of these structures and the recognition of relationships among visual elements lead to the highest levels of aesthetic cognition—perception through analogy and distinction—achieved via geometric harmony between parts and the whole. Although individual characteristics may be general, keen observation combined with structural reflection underpins the artistic process in these works. The Nexus of Art and Science in Islamic Civilization: The alignment of Ibn al-Haytham’s principles with the design patterns of star tiles exemplifies the profound interaction between art and empirical sciences in the Islamic Golden Age. This research elucidates the design process by emphasizing visual perception and the purposeful organization of patterns based on observation, selection, organization, and proportionality. Applying geometric sub-patterns as a bridge between scientific principles and artistic practice underscores that the beauty of star tiles from the 6th to 8th centuries AH is rooted not only in technical skill but also in a systematic perceptual process that reflects Ibn al-Haytham’s aesthetic philosophy. Conclusion: The two main achievements of this research are: 1) Visual unity in star tiles results from the interaction between “particular meanings” (purposeful atomism) and a “geometric holism,” which enhances formal coherence. 2) The consistency between Ibn al-Haytham’s theoretical principles and artistic execution demonstrates a deep connection between art and empirical knowledge—where beauty is understood as a rational-sensory process rather than mere taste. Generally, based on Ibn Haytham’s ideas about the perception of beauty in Zarinfam tiles, it can be said that “perception” is the most significant factor in creating beauty. This perception involves components such as keen observation, conscious thinking, contemplation, and maintaining a balanced understanding of surrounding phenomena. Reliance on logical inference and conditional knowledge is essential for appreciating the beauty in these works.Future research is suggested to expand this framework by exploring the application of optical principles (from <em>Al-Manazir</em>) in other Islamic art forms, such as calligraphy and architecture.
