Numbers of True Believers were drinking and washing themselves at the picturesque fountain, and just as we rose to depart, the voice of a boy-muezzin, on one of the tallest minarets, sent down a musical call to prayer. Immediately the boys left off their sports and started on a run for the great mosque, and the grave, gray-bearded Turks got up from the mats, shoved on their slippers, and marched after them. We followed, getting a glimpse of the illuminated interior of the building, as we passed; but the oda-bashi conducted us still further, to a smaller though more beautiful mosque, surrounded with a garden-court. It was a truly magical picture. We entered the gate, and passed on by a marble pavement, under trees and arbors of vines that almost shut out the moonlight, to a paved space, in the centre whereof was a beautiful fountain, in the purest Saracenic style. Its heavy, projecting cornices and tall pyramidal roof rested on a circle of elegant arches, surrounding a marble structure, whence the water gushed forth in a dozen sparkling streams. On three sides it was inclosed by the moonlit trees and arbors; on the fourth by the outer corridor of the mosque, the door of entrance being exactly opposite. Large numbers of persons were washing their hands and feet at the fountain, after which they entered and knelt on the floor. We stood unobserved in the corridor, and looked in on the splendidly illuminated interior and the crowd at prayer, all bending their bodies to the earth at regular intervals and murmuring the name of Allah. They resembled a plain, of reeds bending before the gusts of wind which precede a storm. When all had entered and were united in solemn prayer, we returned, passing the grand mosque. I stole up to the door, lifted the heavy carpet that hung before it, and looked in. There was a Mevlevi Dervish standing in the entrance, but his eyes were lifted in heavenly abstraction, and he did not see me. The interior was brilliantly lit by white and colored lamps, suspended from the walls and the great central dome. It was an imposing structure, simple in form, yet grand from its dimensions. The floor was covered with kneeling figures, and a deep voice, coming from the other end of the mosque, was uttering pious phrases in a kind of chant. I satisfied my curiosity quickly, and we then returned to the khan.
