Kufic is the oldest calligraphic form of the various Arabic scripts and consists of a modified form of the old Nabataean script. Its name is derived from the city of Kufa, Iraq. although it was known in Mesopotamia at least 100 years before the foundation of Kufa. At the time of the emergence of Islam, this type of script was already in use in various parts of the Arabian Peninsula. It was in this script that the first copies of the Qur'an were written. Kufic is a form of script consisting of straight lines and angles, often with elongated verticals and horizontals. It is still employed in Islamic countries though it has undergone a number of alterations over the years and also displays regional differences. The difference between the Kufic script used in the Arabian Peninsula and that employed in North African states is very marked.
