Cyclorama \Cy`clo*ra"ma\ (s?`kl?-r?"m? or -r?"m?), n. [Cyclo- +
   Gr. "o`rama sight, spectacle.]
   A pictorial view which is extended circularly, so that the
   spectator is surrounded by the objects represented as by
   things in nature. The realistic effect is increased by
   putting, in the space between the spectator and the picture,
   things adapted to the scene represented, and in some places
   only parts of these objects, the completion of them being
   carried out pictorially.
