On 12 May 1867, Napoleon III took the train to Saint-Germain-en-Laye to officially open the musée gallo-romain. He was accompanied by Count de Nieuwerkerke, superintendent of the Beaux-Arts; Alexandre Bertrand, the newly-appointed museum director; and Félicien de Saulcy, president of the Commission de Topographie des Gaules and a renowned numismatist. Morland’s engraving shows the emperor in room 1, dedicated to the earliest periods of prehistory. We can see the Megaloceros and the museum furnishings created by Eugène Millet.
