Land Portraits
Brian Hayes
Modern practice in cartography favors the plan view—the landscape seen as if from an infinite height—but earlier mapmakers were more flexible about perspective. In this map of the Portuguese colony of Macao, drawn in 1646 by Pedro Barreto de Resende, an oblique view conveys information about both the horizontal layout of the town and the vertical scale of the terrain. This technique of land portraiture was known at the time as chorography. The view of Macao is one of about 90 maps reproduced in Mapping the World: Stories of Geography, by Caroline and Martine Laffon (Firefly Books, $39.95). The Laffons emphasize that maps bring us more than the geographic coordinates of a place; they tell us stories about the landscape. For example, in the Barreto map of Macao, the most conspicuous features are fortifications, churches and houses built by the Portuguese. “As for the local population,” the Laffons write, “as on many colonial maps, they seem to be overshadowed by the new ruling class.”—Brian Hayes

About once a month at Sigma Xi headquarters, we liven up the lunch hour with an American Scientist Pizza Lunch talk. In these informal lectures, scientists describe new research to nonscientists. The series is light on jargon but heavy on solid science. Each Pizza Lunch offers an in-depth look at its subject, whether it's bedbugs or the smart grid.
