the sutherland collection has passed by descent to the 7th duke of sutherland, (most of whose wealth is contained in the paintings collection), but in late august 2008 the 7th duke announced that he wished to sell some of the collection in order to diversify his assets. he had offered them as a pair to the british national galleries at £100 million (a third of their overall estimated market price) if they could demonstrate, by the end of 2008, the ability to raise that sum — if not, the pair or other paintings from the bridgewater collection would be put on public auction early in 2009. within days of the duke's decision, the ngs and the national gallery, london had announced they would combine forces to raise the sum, initially in the form of £50 million (or a demonstration that this money could be raised) to purchase "diana and actaeon" and paid over three years in instalments and then £50 million for "diana and callisto" paid for similarly from 2013.
