Herodotus tells us that in ancient times, horsemen were buried with their favourite mount. It is this ancient rite that the artist Pascal Convert wanted to evoke. He scanned the original skeleton of Marengo, Napoleon’s horse, kept in a London museum. Using a 3D printer, he copied the animal’s bones and had the reconstituted skeleton hung above the tomb of Napoleon I at Les Invalides, to mark the bicentenary of his death. The work of art, called “Memento Marengo”, was variously appreciated by the military, historians, and the president of the Napoleon Foundation.
