Today in the roundup: An architectural gem in Fort Worth, the importance of Dallas’ deck park and the case of the missing belt buckle.

Sure, Sotheby’s and Christie’s are in the business of selling artworks through public auction. But not only through public auction, not any more. They’re cutting private deals — like the one that got the Kimbell that Poussin.

Caravaggio and His Followers in Rome will only be seen in the United States at the Kimbell. The show documents how influential the 16th century master once was — despite his short, violent life. But there’s another story here, the story of a young artist starting out in the Big Art Capitol of Europe, finding a patron and leaving his mark — literally.

He’s been dead for more than 400 years, but all the sudden Caravaggio’s everywhere. The question is: why?

Henri Matisse Nu do Dos — or “Back I-IV” — is a landmark work of modernist art. So much so, Fort Worth’s Burnett Foundation decided it ought to sell its set. Problem is, they haven’t sold as a group.

The former director of the Kimbell Art Museum, who committed suicide in March 2010, had works by such modern masters as Robert Motherwell and Al Souza.

It’s ‘The Ordination’ – and something of a coup for the Kimbell. Part of a set of masterpieces painted by Nicolas Poussin in the 1630s, it was bought from the Duke of Rutland, who needed money to work on his family estate, a little place called Belvoir Castle.

Today in the Saturday Spotlight, we’re checking out a few major exhibitions before the close.
