The measure of happiness, or, A royal visit to the Dey of Tunis or the Great Plenipo [graphic].Heath, William, 1795-1840, printmaker[20 July 1820]eng"The Dey of Tunis, a fat Turk, sits cross-legged on one mattress (left), the Princess of Wales, in Turkish costume, on another; her huge breasts are immodestly bare. He smokes a long pipe, and puffs smoke sideways towards his visitor with an inscrutable expression; beside him are coffee-pot and cup. She smokes a hookah; a bottle of 'Coniac' and a glass are beside her. A Tunisian with a long beard and baggy breeches stands between them, staring and bowing towards the Princess; he says: "His Highness Trusts the endeavours of his household for your Gratification is successful and that happiness in the Halb of the Faithfull attends you." She answers: "their Assiduities are unceasing I am as Happy as the Dey [altered to] Day is Long!!!" Behind her couch stands Bergami, in hussar costume with three orders; he scowls with clenched fists, saying: "this is an unfortunate Dey for me Othellos occupation's gone.""--British Museum online catalogueTitle etched below image.Attributed to William Heath in the British Museum catalogue.Sheet trimmed within plate mark.Satire on George IV and Queen Caroline.Printed on watermarked paper.Window mounted to 24.3 x 34.3 cm, the whole then mounted to 58 x 39 cm.Mounted (with one other print) on leaf 47 in volume 1 of the W.E.
