I visited to-day the College of the Mevlevi Dervishes at Pera, and witnessed their peculiar ceremonies. They assemble in a large hall, where they take their seats in a semi-circle, facing the shekh. After going through several times with the usual Moslem prayer, they move in slow march around the room, while a choir in the gallery chants Arabic phrases in a manner very similar to the mass in Catholic churches. I could distinguish the sentences "God is great," "Praise be to God," and other similar ejaculations. The chant was accompanied with a drum and flute, and had not lasted long before the Dervishes set themselves in a rotary motion, spinning slowly around the shekh, who stood in the centre. They stretched both arms out, dropped their heads on one side, and glided around with a steady, regular motion, their long white gowns spread out and floating on the air. Their steps were very similar to those of the modern waltz, which, it is possible, may have been derived from the dance of the Mevlevis. Baron Von Hammer finds in this ceremony an imitation of the dance of the spheres, in the ancient Samothracian Mysteries; but I see no reason to go so far back for its origin. The dance lasted for about twenty minutes, and the Dervishes appeared very much exhausted at the close, as they are obliged to observe the fast very strictly.
