“But first let me tell of the rooms in which it was held. There were seven [...] the windows were of stained glass whose colour varied in accordance with the prevailing hue of the decorations of the chamber into which it opened. That at the eastern extremity was hung, for example, in blue – and vividly blue were its windows. The second chamber was purple in its ornaments and tapestries, and here the panes were purple. The third was green throughout, and so were the casements. The fourth was furnished and lighted with orange – the fifth with white – the sixth with violet. The seventh apartment was closely shrouded in black velvet tapestries that hung all over the ceiling and down the walls, falling in heavy folds upon a carpet of the same material and hue. But in this chamber only, the colour of the windows failed to correspond with the decorations. The panes here were scarlet – a deep blood colour.”
