If any man have a bad memory which he wishes to improve, he should place himself beneath the Golden Ball suspended in the middle of the cupola, and say the morning prayer seven times; three times repeat the words Allahumma Yá káshifo-l mushkilát Yá ’álimu-s-sir va-l khafiyyát (_i.e._ O God who openest all difficult things and knowest all secret and hidden things), and each time eat seven black grapes, and then whatever he hears will remain fixed in his memory as if engraven on stone. A most noted example of this was Hamdí Chelebí, son of Ak-Shemsu-d-dín, who lived in the village of Turbahlí Góïnuk. He was so foolish and forgetful, that if any one gave him the Selám he was obliged to write the word Selám on a piece of paper and read it before he could comprehend that he ought to answer ‘Ve aleïkum es-selám.’ No doctors could do him any good, so that at last he was completely a prey to forgetfulness, till he went, by Ak-Shemsu-d-dín’s advice, to Ayá Sófiyah, where, after saying the requisite prayers, and eating the grapes as prescribed above, beneath the Golden Ball, he was so completely cured of his stupidity, that he began immediately to compose his poem of Yusuf and Zuleïkhá, which he finished in seven months; after which he wrote his Kiyáfet-námeh (Treatise on Physiognomy), which is known all over the world as a wonderful poem on the nature of the Sons of Adam. Fourteenth. The station of the cool window, on the south-east side (Kibleh) of Ayá Sófiyah, on the inner side of the Imperial Gate, is a window opening to the north, where fragrant breezes and songs of the nightingales from the garden outside refresh the soul. It is there that Ak-Shemsu-d-dín, immediately after the conquests, delivered his Lectures on Joreïri’s Commentary on the Korán; and having prayed that all students who pursued their studies there should be blessed with success, that spot has ever since been a delightful place. It was there also that our instructor, the Sheïkh of Sheïkhs, Evliyá Efendí, that master of the art of reading the Korán, delivered his lectures on that science to some thousands of hearers. Fifteenth. The station of the Lord Jesus’s cradle, in a corner on the eastern side of the upper gallery, is a hollow trough of reddish marble like a cradle, where the Christian women used to place their children when sick in order to obtain their recovery.
