Francis bin Fathallah bin Nasrallah Marrash (June 1836 – 1873) was a Syrian writer and poet of the Nahda movement—the Arabic renaissance—and a physician. Most of his works revolve around science, history and religion, analysed under an epistemological light. He travelled through the Middle East and France in his youth, and after some medical training and a year of practice in his native Aleppo, during which he wrote several works, he enrolled in a medical school in Paris; yet, declining health and growing blindness forced him to return to Aleppo, where he produced more literary works until his early death.
Middle Eastern historian Matti Moosa considered Marrash to be the first truly cosmopolitan Arab intellectual and writer of modern times. Marrash adhered to the principles of the French Revolution and defended them in his own works, implicitly criticising Ottoman rule in the Middle East. He was also influential in introducing French romanticism in the Arab world, especially through his use of poetic prose and prose poetry, of which his writings were the first examples in modern Arabic literature, according to Salma Khadra Jayyusi and Shmuel Moreh. His modes of thinking and feeling, and ways of expressing them, have had a lasting influence on contemporary Arab thought and on the Mahjari poets.
