Ottoman-Turkish calligraphy is associated with geometric Islamic art on the walls and ceilings of mosques, as well as on the page.
Contemporary artists in the Islamic world draw on the heritage of calligraphy by using calligraphic inscriptions or abstractions in their work.
The first to gain popularity was the Kufic script – an angular script made of short vertical strokes, long horizontal strokes and bold, compact circles.
The Diwani script is a cursive style of Arabic calligraphy that was developed during the reign of the early Ottomans (16th–early 17th century). It was invented by Housam Roumi and reached its height of popularity under Süleyman I the Magnificent.
