'Bulla contra errores Martini Lvtheri …' issued by Leo X (Leipzig, 1520) [Library shelfmark: Crawford.R.133].
On 15 June 1520, the Medici Pope Leo X issued the bull that threatened Martin Luther with excommunication unless he recanted 41 of his 95 theses.
It begins with the words: 'Rise up oh Lord for the foxes have risen to destroy your vineyard.'
Luther only received the bull in October 1520, four months after it had been issued south of the Alps in Rome.
This document featured in the display 'The Reformation: What was it all about?' that ran at the National Library from 19 October to 10 December 2017.
