Tazhib, also known as Persian illumination, is a traditional decorative art used primarily in manuscripts, calligraphy, and book arts. It involves intricate geometric, floral, and arabesque patterns, often created with fine lines, rich colors, and the use of gold leaf, which gives the art its luminous and refined quality. Rather than depicting figures or narratives, tazhib focuses on harmony, balance, and spiritual beauty, framing and enhancing the main text or image without overpowering it. Rooted in centuries of Persian artistic tradition, tazhib reflects a deep appreciation for precision, patience, and symbolism, and continues to inspire contemporary artists and designers today.
