A first edition of one of the most important works of the man who inspired the Protestant Reformation has been discovered in a library in France.
The publication by German theologian Martin Luther, called On the Freedom of a Christian, dates back to 1520.
This was a year before he was excommunicated by the Pope for criticising the Catholic Church.
It includes around 50 notes written in red by Luther himself, indicating changes he wanted for a second edition.
The American who made the discovery, James Hirsten, said it gave an important insight into Luther’s thinking at the time.
The annotated edition was found in The Humanist Library in Selestat, in the north-east of France.
Martin Luther launched the Reformation in Germany five centuries ago in response to what he said were excesses and abuses within the Church.
