check out the sentence:
As measurement devices have improved, maps have become more accurate and also less artistic. The following maps are from the region in which the current superpowers, Russia and the United States, almost meet. The older map (L126) is from the early 17th century. It was drawn by John Speed (1552–1629), an English cartographer and historian. At first his life took another direction when he followed his father into the tailoring business. It was not until later that his interest in history became an occupation. The map on display was published in a history book written by Speed. The details that fit the time include a drawing of Willem Barentsz’s crew spending the winter on Novaya Zemlya
