The new exhibition is the first to bring together many of the works that were inspired by Blake’s experience of living in Sussex, including paintings commissioned by the Wyndham family, owners of Petworth, and rare hand-coloured relief etchings of Blake’s illustrated epic poem Milton.

Sussex is the only area outside London that Blake ever lived, spending three years there from 1800 to 1803 with his wife Catherine, renting a cottage in Felpham that he described as ‘the sweetest spot on Earth’.

Paintings to go on display include extraordinary works by Blake on loan from the British Museum, National Portrait Gallery and Tate, as well as three paintings by Blake from the Petworth collection and another on loan from the National Trust’s Arlington Court in Devon.

Of the paintings to come from the Petworth collection, two were commissioned by Elizabeth Ilive, mistress and then wife to George Wyndham, the 3rd Earl of Egremont. The third was purchased by the 3rd Earl from the artist’s widow as a philanthropic gesture. Descendants of the 3rd Earl donated the 17th-century mansion to the National Trust in 1947.
