It is a square building supporting a large dome, flanked by semi domes on the south-eastern (Kiblah), and opposite sides. On the right and left of the mosque there are two purple columns of porphyry, of which the like are to be found only in the mosque of Sultán Kaláún, in Caïro; and there is suspended from these a double row of lamps. On the right side of the mosque an elevated gallery has been constructed for the use of the Sultáns of the house of ’Osmán at the public service on Fridays. Sultán Ibráhím subsequently enclosed three sides of the gallery with gilt gratings, so that it resembles a beautiful cage, or net-work, or rather a palace of the immortals. The Mihráb, Minber, and Mahfil, though made of marble, are simple and unornamented; and on the first are inscriptions written in beautiful characters. The mosque has five gates, and the outer court (harem) is adorned with stone benches (soffahs), and on each side a cloister, supported by variegated columns; and in the centre there is a large basin, where all the congregation renew their ablutions. A cupola, supported by eight white marble columns, was placed over the basin by Sultán Murád IV., the Conqueror of Baghdád. On different sides of it four lofty cypresses have been planted. When the foundations of this noble mosque were laid, the Mi’már Báshí having asked the Sultán where he should place the mihráb, was desired by his Majesty to tread upon his foot; having done which, he immediately had a vision of the noble Ka’bah, and knew, consequently, where to place the mihráb. He, therefore, prostrated himself at the Sultán’s feet and began the work, the Sultán having previously offered up a prayer, accompanied by two inclinations of the body, for its happy completion. On the first Friday after it was finished, when there was an assembly of some thousands, the congregation, knowing that the Sultán had never in his life failed to offer up the afternoon (’asr) and evening (’ashà) prayers, insisted on his performing the functions of Imám. The Sultán, being aware that no one present was so well acquainted with those services as himself, consented to perform them. As this mosque was entirely built with lawful money, it has great spiritual advantages; and being situated in the centre of the markets of Islámból, is crowded day and night by thousands of devout Muselmáns, who are offering up their prayers there without ceasing; so that it has often happened that before one party has got through the afternoon (’asr) service, as far as the Ayetu-l Kursí (the verse of the throne, Kor. ii. 256), another coming in prevents the first from finishing. The pipes of the basin in the court are never closed, but pour forth streams of water day and night, because the congregation never fails. This mosque is always illuminated by flashes of light; and before the window of the mihráb there is a garden like that of Irem, adorned with various fruits and flowers,
