Di′o‐ra″ma (?), n. [Gr. � to see through; � = διά through + � to see; cf. � that which is seen, a sight: cf. F. diorama. Cf. Panorama.] 1. A mode of scenic representation, invented by Daguerre and Bouton, in which a painting is seen from a distance through a large opening. By a combination of transparent and opaque painting, and of transmitted and reflected light, and by contrivances such as screens and shutters, much diversity of scenic effect is produced.
