An expert in historic churches and religious objects, Eugène Viollet-le-Duc likely based the design of this reliquary (a receptacle for sacred relics) on a medieval example with a similar gabled roof also embellished with pinecones, a symbol of eternal life. This object was produced by Louis Bachelet’s foundry, probably as a model that never contained relics. The foundry promoted Viollet-le-Duc’s design through a printed catalogue and in its showroom. The finished reliquaries cost between 2,300 and 2,800 francs (over $40,000 today), depending on the extent of the surface decoration and whether it was varnished or gilded.
