When Constance Dry began to experience spontaneous mental images brought on by chronic migraine disease, she termed them "memoryscapes." These memoryscapes were inspired by the landscape of Circle Z Ranch where Dry has spent time since childhood, and they have helped alleviate the pain of migraine. In In Search of Circle Z, Dry explores the relationship between these unbidden images and habitat dioramas, specifically those in the American Museum of Natural History in New York. Through a series of photographs, drawings, and mini-dioramas, she illustrates their similarity and explains how her internal imagery works to provide a place of refuge from pain and a source of new experiences each time they are viewed.Illustrated with color photographs throughout.
