Herbert Matter recalled that in 1942, when they first met over dinner, Jackson Pollock said to him, “It’s a really wonderful time to be living.” He added,“That gave us plenty to think about the rest of the evening.” I wonder how many people would say that today. For my part, after rehearsing a string of problems and miseries irrelevant to the present topic, the amazing exhibition, Pollock Matters, which closes this Sunday (December 9) at the McMullen Museum of Boston College, I would say that we take controversy too seriously. As the debates among the presidential candidates drivel on in equivocation, and the incumbent goes about his work of ruining the country, those Americans who are interested in one of their country’s greatest painters may or may not find themselves sufficiently clear-headed to realize that this exhibition has been so much wrapped up in controversy, that few see its real issues or even care about them. It concerns the discovery of a cache of small experimental works, according to a label made by their owner, Herbert Matter, in 1958, the work of Jackson Pollock, and the collision of the discoverer, Matter’s son, Alex, with the blue-chip institution established by Pollock’s widow.
