panorama n.
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.
vision n.
c. 1300, "something seen in the imagination or in the supernatural," from Anglo-French visioun, Old French vision "presence, sight; view, look, appearance; dream, supernatural sight" (12c.), from Latin visionem (nominative visio) "act of seeing, sight, thing seen," noun of action from past participle stem of videre "to see," from PIE root *weid- "to see."
