Final answer:
The Islamic art form represented by a popular style of writing is calligraphy. This art form is integral to Islamic culture, emphasizing the beauty of written language manifesting in various artistic and architectural works.
Step-by-step explanation:
The popular style of writing that represents a common Islamic art form is calligraphy. Islamic calligraphy is a significant art form in the Muslim world; it is not only a means of conveying language but also an expression of artistic beauty. The Qur'an, written in elegant scripts, signifies Allah's divine word as revealed to Muhammad. Quranic verses are commonly found executed in calligraphy across various forms of art and architecture, highlighting the importance of language and script in Islamic culture.
In Islamic tradition, figural representations are generally avoided as forms of idolatry, which is why mediums such as calligraphic design became crucial. The exquisite use of calligraphy often reflects ideals of beauty, including harmony and balance, and can be highly stylized, showcasing an artist's skill and personal style. This form of art is found in multiple domains, including pottery, textiles, and especially in architectural elements such as the Dome of the Rock in Jerusalem.
Apart from religious texts, Islamic calligraphy also incorporates poetry and other writings, adding to the richness of the visual arts. Overall, it serves as an essential aspect of Islamic culture, reflecting its sophisticated approach to non-figurative art and underlining the intrinsic value placed on language and written word.
