Though many other grammarians could be named, such as Al-Akhfash al Ausat, Abu Amr as Shaibani, Abu Bakr al Anbari, etc., none can be considered so celebrated as the persons above mentioned, who are regarded as the founders of the principles on which Arabic grammar has been established.
In the middle of the third century of the Hijrah (A.D. 816-913), the Arabs first began to distinguish themselves as travellers and geographers. When Muslim Homeir was, in A.D. 845, ransomed from his captivity among the Byzantines and returned to his country, he wrote a book with the title of 'Admonitions on the Countries, Kings and Offices of the Greeks.' Forty years afterwards Jaafar bin Ahmed al Mervezi produced the first geographical work under the title of 'Highways and Countries,' which was followed by those of Ibn Foslan, Ibn Khordabeh, Jeihani, Al-Istakhri, Ibn Haukul, Al-Beruni, Al-Bekri and Idrisi. The great historian, Masudi, was also a writer of travels and an ambassador. Ibn Foslan was sent by the Khalif Muktadir (A.D. 908-932) to the King of the Bulgarians. Abu Dolaf, who accompanied an ambassador from China to the frontiers of that country, made, on his return, a report which Yakut afterwards embodied in his voluminous geographical Dictionary.
A few details will be given about the six chief geographers and travellers of this period, viz., Ibn Khordabeh, Al-Istakhri, Ibn Haukul, Al-Beruni, Al-Bekri and Idrisi.
As regards the first-named, it would appear that he has been the object of considerable controversies among the Orientalists of Europe. After employment in the post and intelligence departments in the provinces, he subsequently came to the court of the Khalif Motamid (A.D. 870-892), and became one of his privy councillors. He is the author of several works on various subjects, but his 'Geography,' says Sir H.M. Elliot, is the only work we possess of this author, and of this there is only one copy in Europe, in the Bodleian Library at Oxford. He died about A.D. 912.
Al-Istakhri, who flourished about the year A.D. 951, obtained his name from Istakhar (i.e., Persepolis), where he was born. He was a traveller whose geographical work has been translated into German by Mordtmann. When Istakhari was in the Indus Valley he met another celebrated traveller, Ibn Haukul, whose book Sir William Ouseley translated in A.D. 1800 into English, under the title of 'The Oriental Geography of Ibn Haukul.' Haukul, who died A.D. 976, had travelled for nearly twenty-eight years in the countries of Islam with the works of Ibn Khordabeh and Jeihani in his hands, and his work, which bears the generally approved title of 'Highways and Countries,' is based on the book of Istakhri.
But the greatest geographer and naturalist of this period is Abu Raihan Al-Beruni (born about A.D. 971), who accompanied Mahmud the Ghaznavide on his invasions to India. He was to Mahmud of Ghazni what Aristotle was to Alexander, with the difference, however, that he actually accompanied the conqueror on his Indian campaigns. He travelled into different countries and to and from India for the space of forty years, and during that time was much occupied with astronomy and astronomical observations, as well as geography. His works are said to have exceeded a camel-load, but the most valuable of all of them is his description of India. It gives an account of the religion of India, its philosophy, literature, geography, chronology, astronomy, customs, law and astrology about a.d. 1030, and has been edited by Edward Sachau, Professor in the Royal University of Berlin. An English edition, containing a preface, the translation of the Arabic text, notes and indices, has also been published. Al-Beruni died at Ghurna A.D. 1038. He used to correspond with Avicenna, who was his contemporary, and who gives in his works the answers to the questions addressed to him by this famous geographer, astronomer, geometrician, historian, scholar, and logician.
Some years later Abu O'beid Abd-Allah Al-Bekri distinguished himself as one of the greatest geographers, with whose labours Quatremere and Dozy and Gayangos have made us better acquainted. He was, by birth, from Andalusia, whence also many others travelled to the East, either for instruction or for trade or as pilgrims, and of whom about a couple of dozen are mentioned by Makkari. Some of these gave descriptions and topographies, to which class of literature also the poetical laudations of celebrated towns belong. Not only Baghdad, Damascus, Cairo, Fez, Morocco and Khairwan were praised or satirized, but also Cordova, Seville, Granada, Malaga, Toledo, Valencia and Zohra were described in Arabic poems. Al-Bekri died in A.D. 1094-1095, and was followed by Idrisi, the author of a work on Arabian geography of some celebrity, and which has been translated into Latin. He died A.D. 1164.
Of historians in Arab literature there are many, but only the most celebrated will be noted. Muhammad bin Ishak, who died about A.D. 767, produced the best and most trustworthy biography of the prophet Muhammad. His work was published under the patronage of the Abbaside princes, and was, in fact, composed for the Khalif Al-Mansur (A.D. 754-775). It was used as the chief source of information by Ibn Hisham, the next historian of note, in his life of the Prophet, which work has been edited by Dr. Wustenfeld, and translated into German by Dr. Weil, and into English by Mr. E. Rehatsek, whose manuscript, however, has not yet been printed. Ibn Hisham, who died in A.D. 828, was the father of Arabic genealogy, and Abu-el-Siyadi, who died in A.D. 857, is next to him.
But the real father of Arabian history was Al-Wackidi, a good and trustworthy historian, thirty-two of whose works are known, all relating to the conquests of the Arabs, and other such subjects. He died A.D. 822. With him generally has been associated his secretary, Muhammad bin Saad, a man of unimpeachable integrity, and of the highest talents, merit, and eminence. He has left us some most interesting works, full of valuable information relating to those times. He died at Baghdad A.D. 844.
Al-Madaini, who died A.D. 839, was the author of two hundred and fifty historical works, of which, however, nothing has yet been discovered, except their titles as given in the 'Fihrist.'
