A remarkable feat was accomplished by Robert Graves: the major gap of text of the "Annals" that had gone lost regarded the end of Tiberius' reign, the whole of Caligula's reign, and the major part of Claudius' reign (the remaining part of Tacitus' manuscript only took up again at this Emperor's death, for the transition to the reign of Nero). Robert Graves' novels "I, Claudius" (1934) and "Claudius the God" (1935) filled the gap perfectly: all the missing parts of the "Annals", up to the latter part of the reign of Claudius himself, were covered by a coherent story. Of course part of it can be considered "mockumentary" in the "Augustan History" tradition (for example how Claudius really felt about republicanism, heavily elaborated by Graves sometimes based on "reconstructed" historical documents, will probably never be really established).
