With vivid memories of his first visit to the Scottish National Gallery in the 1970s and his initial encounter with Hugo van der Goes' The Trinity Altarpiece, Rembrandt's A Woman in Bed, Velazquez's An Old Woman Cooking Eggs and Degas' Diego Martelli, Robert Storr discusses the shifting balance of museum collections from historically 'certified' classics to art whose status and significance remains in active contention and from singular 'treasures' to ensembles that speak to the larger scope of an artist's endeavour. AUTHOR: Robert Storr is an artist, curator and critic and is currently Dean of the Yale School of Art. 22 colour
