On one of the pillars is engraved in early Cufic characters the grandly simple inscription, “This is the tomb of Okba, son of Nafè. May God have mercy on him.” The wooden door of the mosque is very finely carved in a curious design. It is said to have been brought from Tobna, in the high plateau of the Hodna, and to have been formerly covered with precious metals and jewels, which were sold for the benefit of the mosque; but this may be doubted. To obtain a view of the township and the oasis you may ascend the minaret. Here your guide will not accompany you. Arabs object to any prying eye surveying their roofs, which are the resort of their women. They have perhaps grown accustomed to the irrepressible European, who will always go to the highest point at all hazards; he is also beneath their contempt, and in any case will depart and be no more seen. With one of their own countrymen it is different; he may be the European’s servant, but he is a fellow-religionist and not a mere animal like his employer. So the European is tolerated with a shrug. For the office of _muezzin_, the custodian of the mosque, whose business it is to ascend the minaret and call the faithful to prayer, a blind man with a brazen voice is in much request. If not actually, the _muezzin_ is conventionally blind. So he will light a candle to guide you up the dark staircase, and accompany you to the top. The town lies below you and all around,—a curious collection of square mud boxes. On many of the roofs are basket-work erections, which are explained to you as the framework of tents, in which the inhabitants sleep during the great summer heats. Over the heads of countless palm trees your eye ranges to the desert, bounded on the north by the cliffs of Barbary, limitless to the south. And southwards you will gaze till you grow weary of immensity.
