Spiral Jetta by Erin HoganReading Erin Hogan’s road-trip/art history memoir “Spiral Jetta,” about her land art sojourn in the Southwest, I stopped short when she lets slip early on that she learned “to drive in the suburbs of Honolulu.” Her trip begins with a pilgrimage to Robert Smithson’s “Spiral Jetty” in Utah, and a few pages later she writes “I vividly remember the photograph on the cover of my very first art history book, “Artforms” by Duane Preble. It was the first image of ‘Spiral Jetty’ I had ever seen.” Preble, one of Hawai‘i’s most influential artists—he is professor emeritus at the University of Hawai‘i  and  has made an impact on generations of Hawai‘i students—is an Academy trustee. I called him up to tell him about his citation in this well-received book. He was flattered but pointed out that the first edition of “Artforms” featured Christo’s “Running Curtain” on the cover. Still, the always thoughtful Preble pointed out that error or not, Hogan’s reference underscores the power of art, and the hold it can have on the memory and perception.
