SANA, a town of Arabia, the capital of Yemen or Arabia Felix, 4000 feet above the sea, in a beautiful valley extending from N. to S., from 6 to 9 miles broad, and bounded on either side by mountains and table-lands, 110 miles N.N.E. of Hodeida; N. Lat. 15. 22., E. Long. 44. 31. The streets are in general narrow, and the principal one is crossed by a handsome bridge, as in rainy weather a stream of water runs through it. The houses are large, and those of the upper classes have windows filled with fine stained glass. A wall, about 5½ miles in circuit, surrounds the town, and has a few guns; but it is in a very ruinous condition. There are about 20 mosques, in general very splendid, and many of them surmounted by gilt domes. Sana has also a bazaar, and baths similar to those of Egypt. But the principal buildings are the two large palaces of the imam, which have extensive gardens attached to them, the whole being surrounded with fortifications. The architecture of these edifices is Saracenic, with an intermixture of round and pointed arches, but they are devoid of all superfluous ornaments. Most of the artisans in Sana are Jews, who live in a separate quarter of the town, and are subject to much oppression, paying heavy taxes for permission to reside in the town, and for the possession of gardens or vineyards. They, as well as the Banians, who form a large proportion of the population, are obliged to conceal their wealth, and they live by the sale of jewellery, gunpowder, spirits, &c. The most important and wealthy class in Sana are the merchants. The principal article of export is the coffee grown in the vicinity; while tobacco, thread, silk, velvet, glass, dates, spices, sugar, &c., are imported. Sana has been governed by an imam ever since the Turks were expelled from this part of Arabia, in the reign of Solyman the Magnificent. Some ancient inscriptions have been discovered here. Pop. about 40,000.
