A rare 15th Century painting depicting five miracles of Christ has been sold for more than £5.6m at auction.
The triptych has survived through religious purges and political upheaval for more than 500 years in the Almshouse chapel in Sherborne, Dorset.
The sale on Wednesday evening exceeded initial valuations by Sotheby's who estimated it could fetch £3.5m.
Dorset Museum had hoped it could appeal to the Arts Council for a temporary export deferral to allow it more time to raise the money to keep it in the country and on public display.
