whose umbrageous foliage the fiercest rays of a noontide sun cannot penetrate."[65] These oases and the towns situated in them, date from various periods; some of those already discovered being evidently of considerable antiquity. In describing some of these towns, Wellsted says: "The instant you step from the Desert within the Grove, a most sensible change of the atmosphere is experienced. The air feels cold and damp; the ground in every direction is saturated with moisture; and from the density of the shade, the whole appears dark and gloomy. To avoid the damp and catch an occasional beam of the sun above the trees, the houses are usually very lofty. A parapet encircling the upper part is turreted; and on some of the largest houses guns are mounted. The windows and doors have the Saracenic arch; and every part of the building is profusely decorated with ornaments of stucco in bas relief, some in very good taste. The doors are also cased with brass, and have rings and other massive ornaments of the same metal." These descriptions relate to the province of Oman, the eastern extremity of Southern Arabia. The glimpses already obtained of this ancient and famous land, sufficiently prove that the fortunate traveller who shall succeed in obtaining access into the interior of the country, which has always been a _terra incognita_ to Europeans and their descendants, will find an abundance of objects of interest to reward his zeal and self-devotion. There is however another class of interesting objects, relating to the ancient history of the country, which I have not alluded to until now, because I wish to speak of them more particularly. These are the ancient _inscriptions_, of which a number have already been discovered and in part decyphered. Several Arabian writers have stated that there existed in the southern part of their country, before the time of Mohammed, a kind of writing which they call Himyaritic, after the name of the ancient inhabitants of the country, the Beni Himyar. But the confused nature of these accounts, together with the Arab practice of giving the name of Himyaritic to every ancient mode of writing which they were unable to read, caused the story to be regarded as little better than fabulous. In the year 1808 the late Baron de Sacy published a learned treatise on the subject, in which he collected all the Arabian accounts; but no further progress was made in the enquiry, until the discovery of a number of inscriptions on various massy ruins situated along the coast and in the interior, by officers attached to the surveying expedition already spoken of, in the years 1834 and '5.
