Visited Dia:Beacon for the second time yesterday. Enjoyed looking at John Chamberlain's sculptures of crushed and twisted auto parts, Imi Knoebel's wooden forms stacked against the walls, Robert Smithson's glass and sand sculptures, in particular, "The Map of Glass (Atlantis)" and Joseph Beuys's piles of felt weighed down or pedestaled by copper plates. Two very different artists brought close to home the feeling of the sublime. Richard Serra and his colossal elegant forms. Fred Sandback and his drawings in space using yarn. As Sandback himself said, he does not aim to transform the space so much as to co-exist with it. His yarn sculptures do not take up room but they are as solid as Serra's thick sheet metal. How to write and present haiku like that?
