"Each of the cities discussed in this issue was a flourishing commercial and cultural center at one time. Abandoned, but not forgotten, their excavation sites deliver a wealth of information about the past. Take a look at India's Mohenjo-Daro; Mycenae in Greece; Loyang, China's capital of the Eastern Han dynasty; and Machu Picchu in Peru. See what valuable lessons the lost colony on Roanoke Island, Virginia reveal. A word maze, a Chinese scramble, notes on how to recreate a Peruvian pot and more." (text taken from cobblestonpub.com)
