“Van Gogh’s Cypresses,” at the Metropolitan of Art, brings the mad Dutchman’s conifers out of the shade and into the bright light of some of Western art’s most incandescently bendy landscapes. Opening Monday and due to stay up through the end of August, the show brings the south of France to the east of Central Park. It marks the meeting of place and perspective, preserved in paint, with trees that, it seems, were never far from Vincent van Gogh’s vision.
