Fine gilt metal and mother-of-pearl opera glasses with handle made by "Iris Paris". Company mark on both eyepieces. Intact optics. "Iris" was among the most famous manufacturers and opticians. Such opera glasses were used as decorative evening-wear accessories during the 18th and 19th centuries, being useful for viewing the action of the play, opera or concert. Condition: very good. Opera glasses have influenced the design of many other common objects for instance this inkwell, of uncertain age. Multiple draw opera glasses are more rare, as with this patented example in ivory and brass from 1874 (shown on the left). One or two draws would be more normal. The resemblance of this object to two spyglasses is quite striking. Some opera glasses were made for prestige clients from very precious materials. Such objects will often be treated by museums or antique dealers as decorative arts objects rather than optical devices. Indeed the optical power of opera glasses is usually weak, seldom producing a magnification of more than X3, however that is usually adequate to see the action on a stage whilst retaining a bright enough image and a wide field of view.
