Anthony Caro’s sudden death at eighty-nine in October 2013 shocked everyone close to him. Up to his last day in the studio, Caro seemed invincible, even immortal. His appetite for making sculpture was as insatiable as ever. His energy, admittedly now fueled by after-lunch naps, was undiminished, and the demands he made on himself, aesthetically, were, if anything, even greater than before. Caro was proud of his earlier work, but he remained famously uninterested in revisiting the past. His passion and interest were entirely for the sculptures in process and those to come.
