Artist: James Sayers. Published: Hannah Humphrey. In the foreground is a cylindrical altar inscribed 'Sacred to Peace'. Behind and above it, on a high rectangular pedestal, sits Lansdowne, double-headed, as Janus, wearing peer's robes. Both heads smile, one faces three-quarter to the left, the other is in 'profil perdu' to the right. He points a rolled document at a guillotine (left) whose cord is held by a skeleton with the head of Stanhope; the blade is about to be released on the neck of a bull (John Bull), whose head is confined in the machine, fixing the adjacent altar with an agonized stare. Stanhope turns his head to look up at Lansdowne, saying, "Ça ira ça ira ça ira"; he waves a cocked hat in which is a French cockade, the word 'Stanhope' inscribed in the crown. Beside the altar (right) stands the Duke of Grafton, wearing top-boots, looped hat, and his accustomed tight-waisted and full-skirted coat with a star. He holds out a fire-brand to documents which lie on the altar: 'Magna Charta', 'Bill of Rights', 'Act of Settlement', with three volumes of 'Statutes at Large'. The altar is decorated with garlands of olive leaves, with a central emblem of dagger and fire-brand. Behind Lansdowne (right) stands Priestley, his hands folded, looking towards the sacrifice with a beatific smile. Description from the British Museum.
