Perspective boxes were one of a number of optical curiosities or devices introduced into Japan in the 17th to 18th centuries. A variety of lenses and/or mirrors are used along with images painted on the inside of the box, or small objects placed within the box, to create for viewers who peer inside the box a semblance of an experience of a complex, three-dimensional, scene. | Perspective boxes were one of a number of optical curiosities or devices introduced into Japan in the 17th to 18th centuries.
