From This is Lincolnshire:
A 500-year-old letter written by the father of one of Henry VIII’s six wives has been donated to Lincoln Cathedral.
Visitors will now be able to see the note about Anne Boleyn which is said to have started a chain of events radically altering the course of English history and ended with her being beheaded.
International opera singer Jane Eaglen, from Lincoln, has donated the letter.
It will go on display at the cathedral’s Medieval Library in September to commemorate the 500th anniversary of King Henry’s ascension to the throne.
The letter was penned on August 14, 1514, by Sir Thomas Boleyn

The letter that was written to Margerate of austria in 1514 is in fact 495 years old not 500.It will not be the 500th anniversary of this letter until 2014.
so having a 495 year old letter at a 500th anniversary event is nice but isn’t exactly accurate.
