diorama n.

before vowels, di-, word-forming element meaning "through, in different directions, between," also often merely intensive, "thoroughly, entirely," from Greek dia "through; throughout," probably cognate with bi- and related to duo "two" (from PIE root *dwo- "two") with a base sense of "twice."

1796, "a painting on a revolving cylindrical surface," representing scenes too extended to be beheld all at once, coined c. 1789 by inventor, Irish artist Robert Barker, literally "a complete view," from pan- "all" + Greek horama "sight, spectacle, that which is seen," from horan "to look, see," which is possibly from PIE root *wer- (3) "to perceive, observe." Meaning "comprehensive survey, complete or entire view" is by 1801.
