More on possible redactions in Tacitus in the next but one paragraph of the above link.:

No original manuscripts of the Annals exist and the surviving copies of Tacitus' works derive from two principal manuscripts, known as the Medicean manuscripts, written in Latin, which are held in the Laurentian Library in Florence, Italy.[15] It is the second Medicean manuscript, 11th century and from the Benedictine abbey at Monte Cassino, which is the oldest surviving copy of the passage describing Christians.[16] Scholars generally agree that these copies were written at Monte Cassino and the end of the document refers to Abbas Raynaldus cu... who was most probably one of the two abbots of that name at the abbey during that period.[16]
