The eighth-century Codex Eyckensis is a Gospel Book based on two constituent manuscripts that were bound as a single codex from (presumably) the twelfth century until 1988. The Codex Eyckensis is the oldest book in Belgium. Since the eighth century, it has been kept and preserved on the territory of the present-day municipality of Maaseik, in Belgium (hence the name "Eyckensis"). The book was probably produced in the scriptorium in the Abbey of Echternach. It is housed in the church of St Catherine in Maaseik. Source: Wikipedia (en)
