Trompe Loeil (Spelt Trompe L’oeil), is a realistic artistic style, trick, or technique that uses a 2-dimensional application to create an optical illusion of a 3D space or object through a forced perspective.
The modern-day technique originated in the 1800s in Paris as a title for a painting by the famous artist/draftsman Louis-Léopold Boilly. The style name eventually became mainstream in the 1900s, but the technique dates much further back to the height of the Greek and Roman empires, where it was used to make small(er) rooms look (be perceived as) larger.
