Having once more visited the lively house of Ídder, we took our way over the market-places, which were now rather dull. The vultures looked out with visible greediness and eagerness from the pinnacles of the ruined walls around for their wonted food—their share of offal during these days, when so many people were absent, being of course much reduced, though some of them probably had followed their fellow-citizens on the expedition. So few people being in the streets, the town had a more ruined look than ever, and the large heap of rubbish accumulated on the south side of the butchers’ market seemed to me more disgusting than before. We kept along the principal street between Dígi and Arrafíya, passing the deep well Shedwánka on our right, and on the other side a school, which resounded with the shrill voices of about fifty little boys repeating with energy and enthusiasm the verses of the Kurán, which their master had written for them upon their little wooden tablets. Having reached the open space in front of the mosque, and there being nobody to disturb me, I could view at my leisure this simple but curious building, which in the subsequent course of my journey became still more interesting to me, as I saw plainly that it was built on exactly the same principle as the tower which rises over the sepulchre of the famed conqueror Háj Mohammed Áskiá (the “Ischia” of Leo). The mesállaje starts up from the platform or terrace formed by the roof of the mosque, which is extremely low, resting apparently, as we shall see, in its interior, upon four massive pillars. It is square, and measures at its base about thirty feet, having a small lean-to, on its east side, on the terrace of the mosque, where most probably there was formerly the entrance. From this the tower rises (decreasing in width, and with a sort of swelling or entasis in the middle of its elevation, something like the beautiful model adopted by nature in the deléb palm, and imitated by architects in the columns of the Ionic and Corinthian orders) to a height of from ninety to ninety-five feet. It measures at its summit not more than about eight feet in width. The interior is lighted by seven openings on each side. Like most of the houses in Ágades, it is built entirely of clay; and in order to strengthen a building so lofty and of so soft a material, its four walls are united by thirteen layers of boards of the dúm-tree, crossing the whole tower in its entire breadth and width, and coming out on each side from three to four feet, while at the same time they afford the only means of getting to the top. Its purpose is to serve as a watch-tower, or at least was so at a former time, when the town, surrounded by a strong wall and supplied with water, was well capable of making resistance, if warned in due time of an approaching danger. But at present it seems rather to be kept in repair only as a decoration of the town.
