When he loved me with a tender love, I had only to wish and I obtained instantly all that could please me, in rare pearls, in superfine brilliants, sapphires, emeralds, and rubies.  One day, his Majesty allowed me to carry home the famous crown of Agrippina, executed with admirable art, and formed of eight sprays of large brilliants handsomely mounted.  This precious object occupied me for several days in succession, and the more I examined the workmanship, the more I marvelled at its lightness and excellence, which was so great that our jewellers, compared with those of Nero and Agrippina, were as artisans and workmen.

The King, having never spoken to me again of this ornament, I persuaded myself that he had made me a present of it,—­a circumstance which confirmed me in the delusions of my hope.  I thought then that I ought not to leave in its light case an article of such immense value, and ordered a strong and solid casket in which to enshrine my treasure.

The imperial crown having been encased and its clasps well adjusted by as many little locks of steel, I shut the illustrious valuable in a cupboard in which I had a quantity of jewelry and precious stones.  This beautiful crown was the constant object of my thoughts, my affections and my preference; but I only looked at it myself at long intervals, every six months, very briefly, for fear of exciting the cupidity of servants, and exposing the glory of Agrippina to some danger.

The King said then:  “I was ignorant of that fact; but the crown of the Empress, his mother, was not closed at all.  The one which belongs to me is authentic; Madame la Marquise will show it to us:” 

A gracious invitation in dumb show completed this species of summons, and I was obliged to execute it.  I returned to the King in the space of a few minutes, bringing back in its new case the fugitive present, which a monarch asked back again so politely and with such a good grace.

The crown of Agrippina, being placed publicly on a small round table, excited general attention and admiration.  The Italian Princess, Madame de Maintenon, the Duc de Saint Aignan, and Dangeau himself went into raptures over the rare perfection of these marvellously assorted brilliants.  The King, drawing near, in his turn examined the masterpiece with pleasure.  Suddenly, looking me in the face, he cried:
