Here’s a look at a series of portraits of Robert Smithson taken by Nancy Holt during their numerous journeys into the landscape together. “Bob and I both grew up in northern New Jersey, where you could find hidden quarries, forbidden places, scattered throughout the landscape,” Nancy Holt said of her husband, Robert Smithson, in a 2012 interview with the @tate. These trips to national parks and ancient ruins in both the U.S. and the U.K. were important in shaping each artist's practice and ideas about landscape; artworks were often created during or in direct response to these excursions.⁠ “Bob and I were both fascinated by how the landscape over long periods of time has been changed and reformed by human beings out of necessity, not just as something to look at.” To see the entire series, and to learn more about each project, please visit @holtsmithsonfoundation.
