Petroglyphs, an ancient form of rock art, of communication, of pictorial mapping… holds such fascination for me. Perhaps it’s my love of any rock. Or my fascination with the development of creative expression throughout human history, but those ancient pictures, painted or chiselled on cliff faces, are inspiring. Intriguing. They fill my mind with questions. And with stories imagined of lives lived, and the experiences that might have shaped their personalities and the development of our shared culture.
