The German »Lucidarius« is both a continuation of the educational works of Honorius of Autun at the vernacular level and a new departure in terms of conception and systematic approach. Drawing on further sources, notably William of Conches' »Philosophia«, it succeeds in establishing a new scientific emphasis in comparison with Honorius' »Elucidarium«. In its educational approach it is modeled on monastic didactics. Alongside the inclusion of the Latin source texts, the commentary centres on the author's achievement in communicating the knowledge of his day and the specific place occupied by the work in the context of 12th century language and literature.
