BONUS EPISODE: The Declaration of Arbroath - Pluscarden versions

Dauvit Broun introduces the fascinating 'Book of Pluscarden', completed in 1461, whose unknown author included TWO copies of the Declaration of Arbroath and rewrote them in different ways. What did he change and why might he have done so? 

For the 'teaser' of the project's dynamic edition, which will show how the Declaration has been rewritten over time, see https://cotr.ac.uk/dynamic-arbroath/
