“The city of Sana,” says Niebuhr, “is situated at the foot of Mount Nikkum, on which are still to be seen the ruins of a castle, which the Arabs suppose to have been built by Shem. Near this mountain stands the citadel; a rivulet rises upon the other side, and near it is the Bostan el-Metwokkel, a spacious garden, which was laid out by the Imâm of that name, and has been greatly embellished by the reigning Imâm. The walls of the city, which are built of bricks, exclude this garden, which is inclosed within a wall of its own. The city, properly so called, is not very extensive; one may walk around it in an hour. There are a number of mosques, some of which have been built by Turkish Pashas. In Sana are only twelve public baths, but many noble palaces, three of the most splendid of which have been built by the reigning Imâm. The materials of these palaces are burnt bricks, and sometimes even hewn stones; but the houses of the common people are of bricks which have been dried in the sun. “The suburb of Bir el-Arsab is nearly adjoining the city on the east side. The houses of this village are scattered through the gardens, along the banks of a small river. Fruits are very plenteous; there are more than twenty kinds of grapes, which, as they do not all ripen at the same time, continue to afford a delicious refreshment for several months. The Arabs likewise preserve grapes by hanging them up in their cellars, and eat them almost through the whole year. Two leagues northward from Sana is a plain named Rodda, which is overspread with gardens and watered by a number of rivulets. This place bears a great resemblance to the neighborhood of Damascus. But Sana, which some ancient authors compare to Damascus, stands on a rising ground, with nothing like florid vegetation about it. After long rains, indeed, a small rivulet runs through the city; but all the ground is dry through the rest of the year. However, by aqueducts from Mount Nikkum the town and castle of Sana are, at all times, supplied with abundance of excellent fresh water.” After a stay of a week the travellers obtained an audience of leave, fearing that a longer delay might subject them to suspicions and embarrassments. Two days afterward the Imâm sent each of them a complete suit of clothes, with a letter to the Emir of Mocha, ordering him to pay them two hundred crowns as a farewell present. He also furnished them with camels for the journey. Instead of returning by the same road they determined to descend from the hill-country to their old headquarters at Beit el-Fakih, and thence cross the lowland to Mocha.
