The lifelike pictures sometimes appeared to literally jump from the frame. Trompe l’oeil, sometimes called illusionism, is a French term that means “to trick the eye.” This style of photographic realism first appeared in the Renaissance and flourished in the 17th century in the Netherlands. Such techniques were carried to the limit in trompe l’oeil.
For instance, the Altamira bison are strategically painted over bulges of the rock, which enhances the impression of the beasts’ volume ( a). Even prehistoric painters used tricks to make their works appear more realistic. Realism in paintings did not start in ancient Greece. He was defeated, however, because the curtain he tried to pull back was Parrhasios’s painting itself. Convinced of his victory, Zeuxis tried to uncover Parrhasios’s painting to confirm the superiority of his work. Zeuxis uncovered his work: he had painted grapes so realistic that birds flew from the sky to peck at them. Each of the artists brought a covered painting to the contest. Pliny the Elder, in his Natural History, narrates the legendary competition between two renowned painters in ancient Greece: Zeuxis and Parrhasios. When they are successful, the creation is sometimes difficult to distinguish from the model. Realistic painters convey the illusion of reality, volume or distance by making good intuitive use of perspective, color, lighting and shadow. Visual artists often try to imitate reality closely. By studying these failings, we can learn about the computational methods the brain uses to construct visual experience. Because of this disconnect between perception and reality, these optical tricks demonstrate the ways in which the brain can fail to re-create the physical world. When we experience such an illusion, we may see something that is not there, or fail to see something that is there, or even see something different from what is there. Visual illusions are defined by the dissociation between physical reality and subjective perception of an object or event. Applied to architecture, their work continues to astound.

Long before scientists were studying the properties of neurons, artists had devised a series of techniques to “trick” the brain into thinking that a flat canvas was three-dimensional or that a series of brushstrokes was actually a still life. Historically, artists as well as illusionists have used illusions to develop deep insights into the inner workings of the visual system. One of the most important tools neuroscientists use to understand how the brain creates its sense of reality is the illusion. So take a lesson from Socrates: “All I know is that I know nothing.” In other words, the real and the imagined share a physical source in the brain. But the same neural machinery that interprets actual sensory inputs is also responsible for our dreams, delusions and failings of memory. Of course, many experiences in daily life reflect the physical stimuli that enter the brain. Although our sensations feel accurate and truthful, they do not necessarily reproduce the physical reality of the outside world. IT IS A FACT of neuroscience that everything we experience is actually a figment of our imagination.
