Art is a wonderfully tangible pathway to past cultures. In the large collar of a tiny terracotta dog from Harappa, in present-day Pakistan, we learn about people and their dogs four thousand years ago. In beds made of stone inside rock-cutviharas (monastic houses) in the hillside of Ajanta, in India, we glimpse the lives of Buddhist monks in the first century B.C.E. And in pieces of furniture fashioned from ivory and bone found in Begram in Afghanistan, we get a taste of the luxury and artistic skill that people—much like you and I—cherished nearly two millennia ago.
