2. THE ARABIAN LANGUAGE.--The Arabian language belongs to the Semitic family; it has two principal dialects--the northern, which has, for centuries, been the general tongue of the empire, and is best represented in literature, and the southern, a branch of which is supposed to be the mother of the Ethiopian language. The former, in degenerated dialects, is still spoken in Arabia, in parts of western Asia, and throughout northern Africa, and forms an important part of the Turkish, Persian, and other Oriental languages. The Arabic is characterized by its guttural sounds, by the richness and pliability of its vowels, by its dignity, volume of sound, and vigor of accentuation and pronunciation. Like all Semitic languages, it is written from right to left; the characters are of Syrian origin, and were introduced into Arabia before the time of Mohammed. They are of two kinds, the Cufic, which were first used, and the Neskhi, which superseded them, and which continue in use at the present day. The Arabic alphabet was, with a few modifications, early adopted by the Persians and Turks. 3. ARABIAN MYTHOLOGY AND THE KORAN.--Before the time of Mohammed, the Arabians were gross idolaters. They had some traditionary idea of the unity and perfections of the Deity, but their creed embraced an immense number of subordinate divinities, represented by images of men and women, beasts and birds. The essential basis of their religion was Sabeism, or star-worship. The number and beauty of the heavenly luminaries, and the silent regularity of their motions, could not fail deeply to impress the minds of this imaginative people, living in the open air, under the clear and serene sky, and wandering among the deserts, oases, and picturesque mountains of Arabia. They had seven celebrated temples dedicated to the seven planets. Some tribes exclusively reverenced the moon; others the dog-star. Some had received the religion of the Magi, or fire-worshipers, while others had become converts to Judaism. Ishmael is one of the most venerated progenitors of the nation; and it is the common faith that Mecca, then an arid wilderness, was the spot where his life was providentially saved, and where Hagar, his mother, was buried. The well pointed out by the angel, they believe to be the famous Zemzem, of which all pious Mohammedans drink to this day. To commemorate the miraculous preservation of Ishmael, God commanded Abraham to build a temple, and he erected and consecrated the Caaba, or sacred house, which is still venerated in Mecca; and the black stone incased within its walls is the same on which Abraham stood.
