Most relics from the first millennium are made of wood or stone, which is why the Peruvian textiles at the WILLIAM SIEGAL GALLERIES in Santa Fe, New Mexico, are so extraordinary. Crafted by the Huari people between A.D. 500 and 900, the 3-by-6-foot panels are woven with feathers plucked from macaws—and, remarkably, not dyed. Siegal, who has found about a dozen over the years, says he’s always astounded at their state of preservation. “They look like modern art.” From $40,000. At 135 W. Palace Ave.; 505-820- 3300; www.williamsiegalgalleries.com.
