The next interesting result, however, of these Arabian discoveries is, that they disclose not only a civilized and commercial kingdom at a remote antiquity, but that they show us a literary people, who had their own alphabet and system of writing at a date comparable to that of Egyptian hieroglyphics and Chaldæan cuneiforms, and long prior to the oldest known inscription in Phoenician characters. The first Arabian inscriptions were discovered and copied by Seetzen in 1810, and were classed together as Himyaritic, from Himyar, the country of the classical Homerites. It was soon discovered that the language was Semitic, and that the alphabet resembled that of the Ethiopic or Gheez, and was a modification of the Phoenician written vertically instead of horizontally. Further discoveries and researches have led to the result, which is principally due to Dr. Glaser, that the so-called Himyaritic inscriptions fell into two groups, one of which is distinctly older than the other, containing fuller and more primitive grammatical forms. These are Minæan, while the inscriptions in the later dialect are Sabæan. It is apparent, therefore, that the Minæan rule and literature must have preceded those of Sabæa by a time sufficiently long to have allowed for considerable changes both in words and grammar to have grown up, not by foreign conquest, but by evolution among the tribes of the same race within Arabia itself. Now the Sabæan kingdom can be traced back with considerable certainty to the time of Solomon, 1000 years B.C., and had in all probability existed many centuries before; while we have already a list of thirty-three Minæan kings, which number will doubtless be enlarged by further discoveries; and the oldest inscriptions point, as in Egypt, to an antecedent state of commerce and civilization. It is evident therefore that Arabia must be classed with Egypt and Chaldæa as one of the countries which point to the existence of highly civilized communities in an extreme antiquity; and that it is by no means impossible that the records of Southern Arabia may ultimately be carried back as far as those of Sargon I., or even of Menes. This is the more probable as several ancient traditions point to Southern Arabia, and possibly to the adjoining coast of North-eastern Africa, as the source of the earliest civilizations. Thus Oannes is said to have come up from the Persian Gulf and taught the Chaldæans the first arts of civilization. The Phoenicians traced their origin to the Bahrein Islands in the same Gulf. The Egyptians looked with reverence and respect to Punt, which is generally believed to have meant Arabia Felix and Somali-land; and they placed the origin of their letters and civilization, not in Upper or Lower, but in Middle Egypt, at Abydos where Thoth and Osiris were said to have reigned, where the Nile is only separated from the Red Sea by a narrow land pass which was long one of the principal commercial routes between Arabia and Egypt.
