The Aesthetic Movement meets Jules Verne, with a dash of French Deco. The art of Claude and François-Xavier Lalanne, married Parisians who called themselves “Les Lalanne,” even though they mostly created their sculptural pieces separately, is deeply rooted in nature’s flora and fauna. The work is art-historically knowing, yet whimsically inventive. A welded-copper rhinoceros opens into a desk. A bronze-and-copper apple (plucked from the Tree of Knowledge?) has the mouth of a man. A copper-manganese sculpture of a Mallard duck is also a boat from the mind of Captain Nemo. François-Xavier died in 2008 and Claude followed in 2019. This is the couple’s first exhibition in the U.S. in over 40 years. What took so long? —L.J.
