While we're waiting for the curtain to go up, here's something from another book about diamonds:
'...a party was held in the Hall of Mirrors, at Versailles, on Wednesday evening, December 11, 1697, described as "the largest and most magnificent ball that had ever been seen at court....All diamonds look their best in candlelight because each flicker of flame calls forth new brilliance and amazing scintillation. Four thousand candles conspired that night to give the Diamond full, glorious life in its most beautiful setting ever. With seventeen huge arched windows on one marbe eighty-foot-long wall, and seventeen arched mirrors on the other; with sixteen massive chandaliers, twenty-four crystal candelabra, plus two great silver ones with eight branches each; with sixty-four silver tubs on silver bases holding orange trees; with alabaster and blue lapis vases on silver tables; with gleaming silver benches and chairs lined up against the wall; with dancers of both sexes ablaze in diamonds, there was, on that fairy night, a festival of light and fire beyond imagining. The entire Hall of Mirrors became one enormous diamond suspended on the black velvet night beyond.' Taken from HOPE: Adventures of a diamond, by Marian Fowler.
The Diamond was the one hanging from the neck of 'the stooped, stiff-limbed, inflexible Louis XIV, the Sun King. His last years were miserable. 'He sank into a depression, had frequent crying fits, his gout got so bad that he directed his daily council meetings of ministers from his bed'. Once he was overheard sighing: 'God seems to have forgotten all I have done for him.'
Was it the diamond? Collins suffered a similiar fate. He tells us in the preface about the severest attack of gout while writing about the cursed diamond. I can't get myself to believe that his mother's fatal illness was inflicted on her for the same reason.
