From Gilma I passed to Muchtar, corruptly now so called. Its ancient name is Tucca Terebinthina[27]. Dr Shaw[28] says its modern name is Sbeeba, but no such name is known here. I might have passed more directly from Spaitla southward, but a large chain of mountains, to whose inhabitants I had no recommendation, made me prefer the safer and plainer road by Gilma. At Tucca Terebinthina are two triumphal arches, the largest of which I suppose equal in taste, execution, and mass, to any thing now existing in the world. The lesser is more simple, but very elegant. They are both, with all the particulars of their parts, not yet engraved, but still in my collection. From Muchtar, or Tucca Terebinthina, we came to Kisser[29], which Dr Shaw conjectures to have been the Colonia Assuras of the ancients, by this it should seem he had not been there; for there is an inscription upon a triumphal arch of very good taste, now standing, and many others to be met with up and down, which confirms beyond doubt his conjecture to be a just one. There is, besides this, a small square temple, upon which are carved several instruments of sacrifice, which are very curious, but the execution of these is much inferior to the design. It stands on the declivity of a hill, above a large fertile plain, still called the Plain of Surse, which is probably a corruption of its ancient name Assuras. From Kisser I came to Musti, where there is a triumphal arch of very good taste, but perfectly in ruins; the merit of its several parts only could be collected from the fragments which lie strewed upon the ground. From Musti[30] I proceeded north-eastward to Tubersoke, thence again to Dugga, and down the Bagrada to Tunis. My third, or, which may be called my middle journey through Tunis, was by Zowan, a high mountain, where is a large aqueduct which formerly carried its water to Carthage. Thence I came to Jelloula, a village lying below high mountains on the west; these are the Montes Vassaleti of Ptolemy[31], as the town itself is the Oppidum Usalitanum of Pliny. I fell here again into the ancient road at Gilma; and, not satisfied with what I had seen of the beauties of Spaitla, I passed there five days more, correcting and revising what I had already committed to paper. Independent of the treasure I found in the elegance of its buildings, the town itself is situated in the most beautiful spot in Barbary, surrounded thick with juniper-trees, and watered by a pleasant stream that sinks there under the earth, and appears no more.
