An honour from beyond the grave

This curious reliquary jewel, 31/2in (8.4cm) tall and with a pin to the back (probably a later addition) for use as a brooch, is a product of the craze for the Napoleonic era that developed in France after Napoleon’s ashes were returned from St Helena in 1840, and culminated in the election of Louis-Napoleon (subsequently Napoleon III) as President in 1848.
