Procopius's now famous "Anecdota" also known as "Secret History" (, "Apókryphe Historía"; ) was discovered centuries later at the Vatican Library in Rome and published in Lyon by Niccolò Alamanni in 1623. Its existence was already known from the "Suda", which referred to it as Procopius's "unpublished works" containing "comedy" and "invective" of Justinian, Theodora, Belisarius and Antonina. The "Secret History" covers roughly the same years as the first seven books of "The History of the Wars" and appears to have been written after they were published. Current consensus generally dates it to 550, or less commonly, 558.
