“The Bosporus stone with white streaks on black,” used for the floor, was probably the ordinary limestone--black with white veins--used at Constantinople. _Marmor Carystium._--“The fresh green from Carystus,” is the marble now known as cipollino; it was quarried at Carystus, at the foot of Mount Ocha, in the island of Euboea. Its beautiful greenish white surface, marked with broad wavy lines of green or purplish gray, was often praised by the later classical writers. Its resemblance to the markings of a sliced onion is the origin of its name. Modern cipollino need not be confused with true _Carystian marble_, which the ancient material should always be named. _Marmor Phrygium._--“The marble hewn from the Phrygian land towards the Mygdonian heights,” spoken of as “many-coloured,” has been identified as the marble which came from Dokimion near Synnada in Phrygia. The descriptions by Statius and Claudianus of the deep red-veined marble of Synnada agree closely with the Phrygian and Mygdonian stone as described by Paulus. It is a brecciated marble of a rosy colour, slabs of which alternate with verde antique in the panelling of the side aisles of S. Sophia. The quarries at Dokimion were visited by Leake and Texier, and a recent examination of them by M. Leonti[355] disclosed all shades of “violet and white, yellow, and the more familiar brecciated white and rose-red.” This beautiful material is best called Synnadan, as the modern Italian name Pavonazzetto is also used for the streaked marble quarried at Carrara. _Marmor Hierapolitanum._--“The stone from the sacred city Hierapolis.” This marble has been identified by Professor Ramsay.[356] It was found at Thiounta about ten miles N.W. of Hierapolis in Asia Minor. It is variegated like Synnadan, and was much used for sarcophagi; indeed Professor Ramsay says, “On every occasion when its use is mentioned, it was employed to make sarcophagi.” It was called by the name of the great city which is not far distant, “and to which doubtless orders from the outer world were sent. Similarly the marble found at Dokimion was always called Synnadic marble from the time of Strabo, yet Dokimion was thirty-two miles from Synnada.”
