For a similar sulphide scent-bottle see Paul Jokelson, Sulphides, The Art of Cameo Incrustation, New York, 1968, p. 83, fig. 77. Here the reverse is stamped 'C.A.' and the portrait is thought to be William I, King of the Netherlands. The inscription on the present bottle is for H.v. Saken Weimar. Prince Bernhard was a distinguished officer, who, in 1815, after the congress of Vienna, became colonel of a regiment in the service of the King of the Netherlands. As commander of the 2nd Brigade of the 2nd Dutch Division, he played a decisive role for Wellington at both the Battle of Quatre Bras and at the Battle of Waterloo.
