Annales 1-6
This MS was written around 850AD in Germany. The distinctive type of script suggests the event took place in the scriptorium of the Benedictine abbey of Fulda, and this is supported by an explicit reference to Tacitus in the
Annales Fuldenses for 852 (Cornelius Tacitus,
scriptor rerum a Romanis in ea gente gestarum) which seems to show knowledge of
Ann. 2,9.
The script is a pre-carolingian hand which the scribe is changing to Carolingian minuscule, together with occasional small plain majuscules (a 9th century derivative of rustic capitals), a more ornamental version of these letters with decorative shading and some uncial elements, and also a few much larger and heavier capitals of essentially rustic form.
It is generally agreed that it was copied from a text written in 'insular' script which was copied from a manuscript in 'rustic capitals', and it has been suggested that this latter was at least 4th and probably 3rd century, based on an analysis of errors made in copying the titulature and colophons of each book, which are most easily explained if these errors occurred in copying a volume written in the early period in which prose texts were normally written in comparatively large letters and very narrow columns, and the colophons were not laid out in the manner common in 5th century and later books.

At some time after it was written, the MS was transferred to the monastery of Corvey, in Saxony. There it remained, apparently without ever being copied.
In 1508 the volume was removed from the library. A letter of Pope Leo X of December 1, 1517 indicates that it had been stolen, and that Leo had paid a large amount of money for it
4. At all events it passed into the hands of Pope Leo X.

Leo gave the MS to Filippo Beraldo the Younger, who used it to produce the first edition in 1515, and left numerous annotations in the margins of the MS. The monks of Corvey, who petitioned the Pope for the return of their treasure, were instead sent a copy of the printed volume together with an indulgence to make up the balance.
