Editorial note — INDEX
Reading edition
Schefer, Relation des voyages de Nassiri Khosrau(1035-1042 A.D.), pp. 42 and 46. The information from Arab writers collected in the notes to this work must not be confused with what Khosrau himself says. There is, however, one important reference to our material in the text:—we are told that glass, transparent and pure as the emerald, was sold in Cairo by the weight. This was in Fatimi times. There may, perhaps, have been some confusion with the glass weights themselves, of which we have spoken above.
