The Codex Aureus of Echternach is an illuminated Gospel Book, created in the approximate period 1030–1050, with a re-used front cover from around the 980s. It is now in the Germanisches Nationalmuseum in Nuremberg.

A Gospel Book, Evangelion, or Book of the Gospels, is a codex or bound volume containing one or more of the four Gospels of the Christian New Testament – normally all four – centering on the life of Jesus of Nazareth and the roots of the Christian faith. The term is also used for a liturgical book, also called the Evangeliary, from which are read the portions of the Gospels used in the Mass and other services, arranged according to the order of the liturgical calendar.
