A new exhibition in Rome is celebrating one of the most important patron-artist relationships in European history. It's one that propelled a young prodigy named Gian Lorenzo Bernini into a towering figure of Baroque art and architecture.“Bernini and the Barberini,” which opens Thursday, explores the complex relationship between Bernini and Pope Urban VIII, who ruled from 1623-1644. Urban is credited with discovering Bernini and, with him, embarking on a project to make Rome the artistic center of Christian civilization. Urban is being celebrated in a host of Vatican initiatives this year, since he consecrated the new St. Peter’s Basilica in 1626. Urban also put the finishing touches on its interior, including with Bernini’s famous baldacchino canopy over the tomb of the saint.
