Vue d'optique. Prospectus Palatii Regii Somerseti cum Ecclesia S. Mariae Londini: Vista del Palacio Real De Somerset con la Iglesia de Nuestra Señora a Londres
London: 1760. Rare Latin / Spanish version of this copper engraving of Somerset House and St Mary le Strand in London. Circa 1770. Originally designed to be viewed through a zograscope. 28 x 42 cm (image); 36 x 49 cm (sheet). A zograscope is an optical device for magnifying flat images, as the shape of the lens enhanced the sense of the depth shown in the picture. The precursor to 3D images! These were very fashionable in the late 18th century.
Condition: Good condition. Slightly wrinkled / creased, with some small closed tears to sheet edge (not affecting the actual engraving). Few pale spots of foxing. Neat repair to verso. Light water stains, only obvious from otherwise blank verso.
