It was named the Zograscope for reasons lost to us, though it was also more variously and prosaically called a diagonal mirror, an optical pillar machine or an optical diagonal machine. The picture to be viewed was placed on a table and observed through a slanting mirror by means of a lens, large enough to see through with both eyes at once, whose curved edges distorted the image to give a surprisingly good sensation of depth. The surviving examples are elegant and highly collectible pieces of mahogany furniture, designed for the drawing rooms of well-to-do families who desired the latest in technology for their after-dinner entertainment, and who wanted, to quote a catalogue of 1784, to look at “remarkable Views of Shipping, eminent Cities, Towns, Royal Palaces, Noblemen and Gentleman’s Seats and Gardens in Great Britain, France and Holland, Views of Venice, Florence, Ancient and Modern Rome, and the most striking public Buildings in and about London”. These pictures were available at a price of a shilling plain or two shillings coloured, a substantial sum for the period.
