Book of Kells was quartered in the church at Kells, and the governor of the town sent the book to Dublin for safekeeping. Henry Jones, who later became bishop of Meath after the Restoration, presented the manuscript to Trinity College in Dublin in 1661, and it has remained there ever since, except for brief loans to other libraries and museums. It has been on display to the public in the Old Library at Trinity since the 19th century. Over the years, the Book of Kells received several additions to its text. In the 16th century, one Gerald Plunkett of Dublin added a series
The Secret of Kells in which a poet is confronted by a dream or vision of a seeress, in the naming of the forest sprite encountered by Brendan. Wider mythological similarities have also been commented upon, such as parallels between Brendan's metaphysical battle with Crom Cruach and Beowulf's underwater encounter with Grendel's mother. "The Secret of Kells" began development in 1999, when Tomm Moore and several of his friends were inspired by Richard Williams's "The Thief and the Cobbler", Disney's "Mulan" and the works of Hayao Miyazaki, which based their visual style on the respective traditional art of the cultures featured in each film.
