Harold Lamb,
The Witch of Aleppo — Chapter 9
(1924)
“ It seemed to him that the torture chamber was the base of the tower, as the walls were of massive black basalt and the columns supporting the ceiling were thick as buttresses, instead of the slender pillars of Arabic design. In fact the grim, black tower with its rounded cupola was like nothing else in Aleppo. Perhaps it had been built centuries ago for an astrologer—certainly it served to guard Sidi Ahmad from assassins. All at once Michael stiffened where he sat in a corner of the torture chamber. A slight sound had reached him, the muffled gritting of iron against stone. ”
