“Baghdad was a veritable City of Palaces, not made of stucco and mortar, but of marble. The buildings were usually of several stories. The palaces and mansions were lavishly gilded and decorated, and hung with beautiful tapestry and hangings of brocade or silk. The rooms were lightly and tastefully furnished with luxurious divans, costly tables, unique Chinese vases and gold and silver ornaments.”
