A UK Telegraph article forwarded by Caitlin Burns, of StarlightRunner Entertainment:
The parchment document, which bears the red wax seals of more than 80 English lords, cardinals and bishops, was sent to Pope Clement VII in 1530 but failed to resolve the dispute, which eventually led to religious schism and the founding of the Church of England.
It will be displayed alongside documents from the heresy trial of Galileo Galilei, whose scientific theories attracted the hostility of the Catholic Church in the early 17th century.
One of the most unusual documents is a letter written on birch bark in 1887 by the Ojibwe Indians of Ontario, Canada, to Pope Leo XIII.
Other previously unseen documents relate to Pope Pius XII, who has been accused of not doing enough to speak out about the Holocaust during the Second World War.
There is no manner of description that can present this as anything other than an amazing opportunity to take a gander at artifacts the Vatican has almst literally been sitting on for centuries.
