Until the end of the 11th century, Dutch literature, like literature elsewhere in Europe, was almost entirely oral and in the form of poetry. In the 12th and 13th century, writers starting writing chivalric romances and hagiographies for noblemen. From the 13th century, literature became more didactic and developed a proto-national character, as it was written for the bourgeoisie. With the close of the 13th century a change appeared in Dutch literature. The Flemish and Hollandic towns began to prosper and a new sort of literary expression began. Around 1440, literary guilds called "rederijkerskamers" ("Chambers of Rhetoric") arose which were usually middle-class in tone. Of these chambers, the earliest were almost entirely engaged in preparing mysteries and miracle plays for the people. Anna Bijns (c. 1494–1575) is an important figure who wrote in modern Dutch. The Reformation appeared in Dutch literature in a collection of Psalm translations in 1540 and in a 1566 New Testament translation in Dutch. The best-known of all Dutch writers is the Catholic playwright and poet Joost van den Vondel (1587–1679).
