Leigh's case, however, was not so hard as that of a monk, who wrote and published the 'Anatomy of the Mass,' in 1561. The work itself contained only one hundred and seventy-two pages, to which were added FIFTEEN pages of _errata_. The pious monk wrote an apology for these inaccuracies, which, if true, proved that his case was indeed a cruel one--clearly proving, moreover, that even if the devil had originally assisted Doctor Faustus and Gutenberg in the invention, his brimstone majesty very soon became sick of his bargain. The monk avers that he wrote the work to circumvent the artifices of Satan, and that the devil, ever on the alert, undertook to circumvent him. For this purpose Satan, in the first place, caused the MS. to be drenched in a kennel, until it was rendered comparatively illegible; and, in the second place, he compelled the printers to perpetrate more typographical blunders than had ever before been made in a book of no greater magnitude. But the malice of Lucifer did not end here. He compelled the priest to act under his influence while making the corrections! But they were not all unintentional errors of the press in those days that appeared such. There were words and phrases interdicted by the Pope and the Inquisition; and sometimes by adroit management the interdicted word, though not inserted in the text, could be arrived at in the table of _errata_. It is a singular fact, that the edition of the Latin Vulgate, by Pope Sixtus the Fifth, although his Holiness carefully superintended every sheet as it passed through the press, has ever remained without a rival in typographical inaccuracy. Still more curious was the fact, that the Pope, in the plenitude of pontifical infallibility, prefixed to the first volume a bull of excommunication against any and every printer, who in reprinting the work, should ever make any alteration in the text. To the amazement of the public, however, when the Bible appeared, it swarmed with errors too numerous for an errata. In a multitude of instances it was necessary to reprint whole passages in scraps, and paste over the incorrect verses. Great efforts were made to call in the edition; and it is now only to be found among rare collections, as a monument of literary blunders. If the Devil ever troubles himself about the correction of proofsheets, he was much more likely to be standing at the Pope's elbow while the Bible was printing, than to be bothering his head in regard to the poor monk's mass book to which allusion has been made. Typographical errors happen in a variety of ways; sometimes by carelessness, sometimes by the ignorance and stupidity of the printer, and sometimes by design. Occurring in either way, they are often ludicrous, and sometimes productive of positive evil. A few examples of each variety will suffice.
