A view wide enough to include what a single glance would miss. Breadth bought at the cost of detail.
Greek πᾶν (pan, all) + ὅραμα (horama, a view, from ὁρᾶν, to see); coined in the late 18th century by the painter Robert Barker for his wide painted views, a word invented for a whole seen at once.
A view deliberately made wide enough to hold what a single glance would miss, bought at the cost of any one part's detail.
