Apart from the buildings themselves, what items of particular historical value were lost during Henry VIII's reign? Wikipedia's 'Dissolution of the Monasteries' makes some mention of libraries but does not say which documents of particular value were lost forever (other than manuscripts of church music). For example, were any chronicles destroyed? What can we tell from documents that are referenced in surviving manuscripts?
Also, I know that some tombs were destroyed (e.g. Thomas Becket) and some burial locations lost (e.g. at Blackfriars, those of Henry and Alphonso, children of Edward I). Were any other royal/noble burial sites destroyed or lost, especially from early Anglo-Saxon times up to the reign of Edward I?
I'm not looking for a list, more of an overview. I'm trying to get an idea of how much knowledge was lost.
