Dinant, Huy, and Liège, traded with Germany, where Wallengassen (Walloons' neighborhoods) were founded in certain cities. In Cologne, the Walloons were the most important foreign community, as noted by three roads named Walloonstreet in the city. The Walloons traded for materials they lacked, such as copper, found in Germany, especially at Goslar. In the 13th century, the medieval German colonization of Transylvania (central and North-Western Romania) also included numerous Walloons. Place names such as Wallendorf (Walloon Village) and family names such as Valendorfean (Wallon peasant) can be found among the Romanian citizens of Transylvania. Walloons in the Renaissance In 1572 Jean Bodin made a funny play on words which has been well known in Wallonia to the present: Translation: "We are called Walloons by the Belgians because when the ancient people of Gallia were travelling the length and breadth of the earth, it happened that they asked each other: 'Où allons-nous?' [Where are we going? : the pronunciation of these French words is the same as the French word Wallons (plus 'us')], i.e. 'To which goal are we walking?.' It is probable they took from it the name Ouallons (Wallons), which the Latin speaking are not able to pronounce without changing the word by the use of the letter G." One of the best translations of his (humorous) sayings used daily in Wallonia is "These are strange times we are living in." Shakespeare used the word Walloon: "A base Walloon, to win the Dauphin's grace/Thrust Talbot with a spear in the back." A note in Henry VI, Part I says, "At this time, the Walloons [were] the inhabitants of the area, now in south Belgium, still known as the 'Pays wallon'." Albert Henry agrees, quoting Maurice Piron, also quoted by A.J. Hoenselaars: "'Walloon' meaning 'Walloon country' in Shakespeare's 'Henry VI'..." Walloons in Sweden Starting from the 1620s, numerous Walloon miners and iron-workers, with their families, settled in Sweden to work in iron mining and refining. Walloon methods of iron production were incorporated into Swedish practice, to supplement the existing German techniques. Many Walloon workers settled around the mine at Dannemora producing Öregrund iron which represented 15 per cent of Sweden's iron production at that time. They were originally led by the entrepreneur Louis de Geer, who commissioned them to work in the iron mines of Uppland and Östergötland. The wave of migration continued substantially into the 18th century. Walloons became
