I got the call late on a summer afternoon. Yanai Segal, an artist I’ve known for years, asked me whether I’d heard of the Salvator Mundi—the painting attributed to Leonardo da Vinci that was lost for more than two centuries before resurfacing in New Orleans in 2005. I told him that I’d heard something of the story but that I didn’t remember the details. He had recently undertaken a project related to the painting, he said, and wanted to tell me about it.

The Salvator Mundi—“Savior of the World”—was most likely completed at the turn of the 16th century. An oil painting rendered on a walnut panel, it depicts Jesus offering a blessing with his right hand while holding an orb that represents Earth with his left.
