This is an interesting example of an item from an early collection being adapted to fit a later piece, of similar design.
The inner frame that holds the eight gilt scent bottles, with an oval central filigree compartment could possibly be the ‘Gold Case for Essence Bottles, of philligrin’ mentioned in the 1690 Deed of Gift, or Devonshire Schedule.
This recorded a massive bequest to Anne, Countess of Exeter (1649-1703), from her mother, Elizabeth Cavendish, Countess of Devonshire (1619-1689).
The bottles bear the mark of John Chartier, a Huguenot working in London in the 17th Century.
The 18th Century filigree casket that contains them is decorated with enamel plaques, possibly Dutch in origin, some of which are heart-shaped and may indicate a gift or love-token.
