Having described the countries of the “numerous peoples of the Slavs,” the late twelfth-century chronicler Helmold of Bosau added, “If you consider Hungary as a part of Slavania, as some would suggest, because it does not differ by customs or by language, the area of the Slavic language extends so far that a proper estimate is quite lacking.” These few words indicate how clearly local the chronicler's horizon was—the farther away from Wagria, the fuzzier his information. At the same time, though, Helmold made plain that the Slavic language was for him an essential element of what Slavania was. As a parish priest at the forefront of missionary and settlement activities, Helmold wrote a chronicle that is a unique source of information for intercultural interactions between Germans and Slavs during the high medieval colonization period.
