One continent, one language? Europa Celtica and its language in Philippus Cluverius' Germania antiqua (1616) and beyond.

Today's European Union is keen to point out that one of Europe's main characteristics is its linguistic diversity. Some early-modern scholars, however, emphasised the notion of European monolingualism, even though Europe's linguistic diversity was as obvious in the sixteenth through eighteenth centuries as it is today. These scholars advanced the argument that, in a distant past, Europeans had spoken one single language. This article focuses on the first scholar to really substantiate this idea. In his voluminous Germania antiqua (1616), the Leiden founder of historical geography, Philippus Cluverius, set out to prove that Europe had once largely been populated by people who shared one single language and a set of distinctive customs. After analysing Cluverius' argument and his linguistic image of Europe, the article will outline the intellectual background behind his claims and map his work's impact on later representations of Europe in terms of language. Even when most early-modern scholars admittedly rejected the idea of Europe as a historical linguistic unity, the paper will show that the notion of Europe was a crucial point of reference in the linguistic scholarship of the early-modern period.
