Binoculars, Brass, Original Wooden Case, Lined with Green Felt.

The binocular is an optical instrument consisting of two similar telescopes, one for each eye, mounted on a single frame. When Hans Lippershey first applied for a patent on his instrument in 1608, he was asked to build a binocular version. He reportedly did so late that year. Box-shaped binocular terrestrial telescopes were produced in the second half of the 17th century and the first half of the 18th century by Cherubin d’Orleans in Paris, Pietro Patroni in Milan and I.M. Dobler in Berlin. These were not successful because of their clumsy handling and poor quality. Credit for the first real binocular telescope goes to J. P. Lemiere who devised one in 1825. The modern prism binoculars began with Ignazio Porro's 1854 Italian patent for a prism erecting system.
