Is Venable’s vision for his museum misguided, or a clarion call for a struggling industry to cast aside its pieties in pursuit of a purely rational bottom line? As of last October, the Indianapolis Museum of Art has rebranded itself as Newfields: A Place for Nature and the Arts. Admission is no longer free, and your $18 ticket brings you into a wonderland of flowering gardens, foreign delicacies, theatrical performances, cat-video festivals, mini-golf, beer gardens, and, should you be into such things, an art museum, too.
