Kitab Kashf al-Hijab fi 'Ilm al-Hisab. كتاب كشف الحجاب في علم الحساب

Butrus al-Bustani was a writer and scholar from the present-day Lebanon. He was a major figure in the Nahda, which began in Egypt in the late 19th century and spread to the Middle East.
He is considered to be the first Syrian nationalist, due to his publication of Nafir Suria, which began following the 1860 Mount Lebanon civil war. In 1870, he founded Al-Jinan, the first important example of literary and scientific periodicals, which began to appear in Arabic in the 1870s alongside the independent political newspapers.
