Document 2: Hein van Aken: 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.

Document 5: Dutch-language literature: Dutch-language literature comprises all writings of literary merit written through the ages in the Dutch language, a language which currently has around 23 million native speakers. Dutch-language literature is the produce of Netherlands, Belgium, Suriname, the Netherlands Antilles and of formerly Dutch-speaking regions, such as French Flanders, South Africa, and Indonesia. The Dutch East Indies, as Indonesia was called under Dutch colonization, spawned a separate subsection in Dutch-language literature. Conversely, Dutch-language literature sometimes was and is produced by people originally from abroad who came to live in Dutch-speaking regions, such as Anne Frank and Kader Abdolah. In its earliest stages, Dutch-language literature is defined as those pieces of literary merit written in one of the Dutch dialects of the Low Countries. Before the 17th century, there was no unified standard language; the dialects that are considered Dutch evolved from Old Frankish. A separate Afrikaans literature started to emerge during the 19th century, and it shares the same literary roots as contemporary Dutch, as Afrikaans evolved from 17th-century Dutch. The term Dutch literature may either indicate in a narrow sense literature from the Netherlands, or alteratively Dutch-language literature (as it is understood in this article).
