What is the take of Catholic Church on Codex Gigas?

The National Library of Sweden has a rare manuscript by the name [Codex Gigas](https://en.wikipedia.org/wiki/Codex_Gigas) . It is a compilation of texts including those of both Old and New Testaments, a medical book, chants etc. One curious thing about the book is that it has, towards the end, a full-page illustration of the devil! The manuscript is said to have been made by a Benedictine monk of Bohemia in the 13th century. There are some legends that are not in good taste, concerning the creation of the manuscript. One would like to know what the take of Catholic Church is, on the realities and stories involving Codex Gigas.
