Trompe-l'oeil is a common painting technique that suggests an optical illusion that appears deceptively realistic, like a painted door on a wall. The term comes from French and literally means 'deceives the eye'. On Delft pottery, this technique only occurs with birdcage plaques that were only made for a short time, roughly from 1750 to 1780.
