The gospels other than John are "written for the most part in a rapid cursive script", while John is "by a different scribe, in neat minuscule bookhand". It was signed by its scribe, Dimma MacNathi, at the end of each of the Gospels. Legend says that Dimma wrote the book in forty days and forty nights without rest, food or water and because he did it like this Dimma thought he had done it in one day. Studies however by Dr R.I. Best show that the book was written by many hands. The Book is now housed in the library of Trinity College.
