The Literary and Linguistic Computing Centre was established in the University of Cambridge in 1964. The work of the Centre was concentrated on the production of word-indexed, concordances and lexico-graphical materials in several languages for scholars with literary and philological interests. The present volume contains a complete word-index, a ranking list of frequencies, a reverse index and a rhyming index to both Bespiegelingen van Godt and Godtsdienst and Lucifer by Joost van den Vondel (1587–1679), the Dutch poet and dramatist. Bespiegelingen, a long verse work (66531 words), contains a rationale of the doctrine underlying many of Vondel's best-known dramatic works. Because of this, and due to its length and the monumental development of its argument it has been comparatively little studied, Bespiegelingen presented ideal material for analysis by computer. Lucifer, generally considered to be Vondel's masterpiece, was an obvious choice to head the list of original plays.
