(1904)
“ Far in the gallery's amber-tinted gloom the red of Ispahan dominated, subduing fiery vistas to smoldering harmony through which, like a vast sapphire set in opals, glimmered the superb lost Persian blue. There was one other rug, an Eighur, the famous so-called "Babilu," or "Carpet of Belshazzar"; but it hung alone in imperial magnificence behind the locked doors of a marble room, which it seemed to fill with a soft luster of its own, radiating from the mystic "Tree of Heaven" woven in its center. ”
