For nearly three decades, the Rouillac auction house has been staging its celebrated Garden Party, which returns each year with its share of dramatic turns. The 2018 vintage certainly kept up the tradition, with a total of over €10,300,000 for 10 June alone. A large porcelain moon vase with the famous square mark of the Qianlong Emperor (1736-1795) was knocked down for €5,089,000 to a French buyer, who battled with nine groups of bidders from China and its diaspora. A world record for this type of artefact was merited because "there are only two moon vases like this in the world, so it is priceless," says Maître Rouillac. (The other was sold for €1,801,00 in April 2016 at Sotheby's Hong Kong.) The vase was probably brought back from China by an ancestor of the family, a general staff officer in the French royal navy, between 1842 and 1847. The other star of the show, "Christ enfant méditant sur les instruments de la Passion", fetched €3,596,000. This masterpiece by the Le Nain brothers was unknown until recently, when it was discovered by Maître Rouillac at a house in the Vendée. This posted a world record for a work by the artist brothers, despite being forbidden to leave the territory, as a national treasure, by the Ministry of Culture. It fired the enthusiasm of three French collectors, one of whom carried it off without interference from the Musées Nationaux, which unexpectedly did not invoke their right to pre-empt.
