Scientific interests
Art
The artist William Blake lived near Petworth for a while, and Elizabeth is thought to have commissioned several works from him. The unnamed woman in Blake's Vision of the Last Judgment is believed to represent her.Her husband, the earl, was a patron of J. M. W. Turner, and Elizabeth is believed to have assisted Turner with the creation of pigments in her own "laboratory". Evidence for this includes the existence of receipts for artists’ supplies, glass and earthenware retorts, imploding bottles, Magdeburg hemispheres, and yellow powder.
