Islamic art
Calligraphic design is omnipresent in Islamic art, where, as in Europe in the Middle Ages, religious exhortations, including Qur'anic verses, may be included in secular objects, especially coins, tiles and metalwork, and most painted miniatures include some script, as do many buildings. Use of Islamic calligraphy in architecture extended significantly outside of Islamic territories; one notable example is the use of Chinese calligraphy of Arabic verses from the Qur'an in the Great Mosque of Xi'an. Other inscriptions include verses of poetry, and inscriptions recording ownership or donation. Two of the main scripts involved are the symbolic "kufic" and "naskh" scripts, which can be found adorning and enhancing the visual appeal of the walls and domes of buildings, the sides of minbars, and metalwork. Islamic calligraphy in the form of painting or sculptures are sometimes referred to as "quranic art".
History of writing
There have recently been discoveries of tortoise-shell carvings dating back to c. 6000 BC, like Jiahu Script, Banpo Script, but whether or not the carvings are complex enough to qualify as writing is under debate. At Damaidi in the Ningxia Hui Autonomous Region, 3,172 cliff carvings dating to 6000–5000 BC have been discovered, featuring 8,453 individual characters, such as the sun, moon, stars, gods, and scenes of hunting or grazing. These pictographs are reputed to be similar to the earliest characters confirmed to be written Chinese. If it is deemed to be a written language, writing in China will predate Mesopotamian cuneiform, long acknowledged as the first appearance of writing, by some 2,000 years; however it is more likely that the inscriptions are rather a form of proto-writing, similar to the contemporary European Vinca script.
