This week our subject is Cy Twombly, one of the most celebrated artists of the twentieth century. A new major exhibition of his work, Cy Twombly: Making Past Present, organised by the MFA in Boston and the Getty Museum in LA, surveys Twombly's immense debt to antiquity. Patrick McCaughey reviews the related catalogue for our upcoming April issue. In this wide-ranging conversation with Peter Rose, he also talks about the plight of US museums during the pandemic, the vexed question of de-accessioning, and the diaries of Fred Williams, which he is currently editing.
