Osman Waqialla
Osman Waqialla (Arabic: عثمان وقيع الله, 1925−4 January 2007), was a 20th century Sudanese painter and calligrapher, noted for his creative use of Arabic letter forms in his artworks, thereby integrating African and Islamic cultural traditions into the contemporary art of Sudan. This use of Arabic calligraphy as a modern, non-religious graphic form places Waquialla within the Arabic art movement that became known as the Hurufiyya movement.
