Researchers from Texas State University have used forensic astronomy to uncover new details about Claude Monet's Étretat: Sunset — a stunning seascape that the impressionist master painted during a trip to the Normandy coast in 1883. Their findings, published in the February 2014 issue of the magazine Sky & Telescope, reveal the exact spot and time at which Monet painted the work, based on extensive fieldwork and astronomical data.
Led by astrophysicist Donald Olson, the team traveled to the cliffs of Normandy in 2012, where they used postcard-size replicas of Monet's works to identify the precise vantage point from which he painted Étretat: Sunset. Once they identified the location, they used planetary software to determine what a...
