 Be that as it may, a second note sets on more solid grounds the attribution of the annals down to 864 to Rudolf of Fulda, whose manuscript, though not conserved, is mentioned in independent sources and has left traces in the tradition.Some scholars believe that the whole work was first put together by an unknown compiler only in the 870s.It has also been suggested that they were continued after 864 by Meinhard, but very little is known of this continuator of Rudolf's work.
