Calligraphy has been central to Iran's cultural identity. Handwritten, poetic works by Shahnameh, Hafez and Khayan, as well as the Holy Quran are revered for the artistic value they hold. The country also boasts of a distinct collection of calligraphic styles such as Kufic, Taliq, Naskh, Req and Shekasteh. The art form also blends with Iranian painting through the form of Naqashi-Khat.
