Hein van Aken, also called Hendrik van Aken or van Haken, was the parish priest in Korbeek-Lo, between Leuven and Brussels.
 He was born in Brussels, probably in the thirteenth century.
 He translated the "Roman de la Rose" by Guillaume de Lorris and Jean de Meun to Dutch, with the title "Het Bouc van der Rosen", and is probably also the poet of the "Historie van Saladyn".
 With less reason, some also attribute the "Natuurkunde van het Geheel-al" to him, but a poem by him must be kept in the Comburger manuscript.
 In the "Leeckenspeigel", some work by him has been intertwined, amongst others his rhymed essay "Over de Dichtkunst" ("On Poetry"), which has been called remarkable by skilled reviewers because of the common sense that prevails in it.
The Flemish or Flemings (Dutch: "Vlamingen" ) are a Germanic ethnic group native to Flanders, in modern Belgium, who speak Dutch, especially any of its dialects spoken in historical Flanders, known collectively as Flemish Dutch.
 They are one of two principal ethnic groups in Belgium, the other being the French-speaking Walloons.
 Flemish people make up the majority of the Belgian population (about 60%).
 Historically, all inhabitants of the medieval County of Flanders were referred to as "Flemings", irrespective of the language spoken.
 The contemporary region of Flanders comprises a part of this historical county, as well as parts of the medieval duchy of Brabant and the medieval county of Loon.
The Dutch (Dutch:    ), occasionally referred to as Netherlanders—a term that is cognate to the Dutch word for Dutch people, "Nederlanders"—are a Germanic ethnic group native to the Netherlands.

 Dutch people and their descendants are found in migrant communities worldwide, notably in Aruba, Suriname, Guyana, Curaçao, Chile, Argentina, Brazil, Canada, Australia, South Africa, New Zealand, and the United States.
