Women and Freemasonry: The Centenary. Since its formation in England in 1717, membership of the Freemasons was restricted to men. This exhibition, the first in the UK, marks the foundation in 1908 of the first Grand Lodge in England open to men and women - one result of the campaign begun by women at the end of the previous century to gain full civic and legal rights.

*Portraits from Chequers. Since 1921, Chequers has been the official country house of Britain's Prime Ministers. Built in the 16th century it was, in the early twentieth bought, restored and harmoniously furnished by Lord and Lady Lee, who eventually decided to give the Buckinghamshire estate to the nation as a country retreat for its Prime Ministers - where they can relax and entertain in helpful rural privacy.

More or less by definition therefore the Chequers collections are unknown to the public, until now with a selection of especially interesting historical works on loan to Compton Verney where they are displayed in its splendid British Portraits Gallery. Two fine portraits by Anthony Van Dyck of Charles I and his wife Henrietta Maria are outstanding as are in markedly different ways Jacob Huysmans's portrait of Elizabeth Claypole, Oliver Cromwell's daughter, and Hans Eworth's of Lady Mary Grey. Queen Elizabeth I's Locket Ring containing tiny bejewelled portraits of herself and her mother Anne Boleyn is as touching as Philip de Laszlo's swish portrait of The Last Days at Chequers of Lord and Lady Lee.
