The Dulwich Picture Gallery has many good scans from its amazing collection online, but the site is slow and is hampered by inconsistent searching and the inability to "browse" effectively. Here are the works we have catalogued by Peter Paul Rubens:   Peter Paul Rubens at the Dulwich Picture Gallery Catherine Manners, Duchess of Buckingham(?) Ceres and Two Nymphs with a Cornucopia Hagar in the Desert Romulus setting up a Trophy Saint Barbara fleeing from her Father Saints Amandus and Walburga Saints Catherine of Alexandria and Eligius St Ignatius Loyola exorcising The Three Graces Venus mourning Adonis Venus, Mars and Cupid
