Sixtus V, Pope from 1585 to 1590 authorized a printing of the Vulgate
Bible.  Taking no chances, the pope issued a papal bull automatically
excommunicating any printer who might make an alteration in the text.
This he ordered printed at the beginning of the Bible.  He personally
examined every sheet as it came off the press.  Yet the published
Vulgate Bible contained so many errors that corrected scraps had to be
printed and pasted over them in every copy.  The result provoked wry
comments on the rather patchy papal infallibility, and Pope Sixtus had
no recourse but to order the return and destruction of every copy.
