Introduction:-

Perception and perspective are essential and fundamental to the creative process as we learn more about the art world. Our cognitive abilities and the incredible tool of the human eye play a crucial role, continually collecting data and moulding our perception of the world. Our understanding of depth, size, and shape is not a direct representation of reality but rather an intricate human cognitive process in the visual system that depends on multiple signals to understand the three-dimensional world based on two-dimensional retinal pictures.

The factors contributing to the perception of depth in a scene include linear perspective, the phenomenon where parallel lines seem to converge in the distance. In relative size, objects closer to the viewer appear more significant than those farther away, and overlapping figures, objects that partially block others, are perceived as being closer. Light and shadow help define the shape and depth of “Perspective and Perception” : The Art of Optical Illusions 2 objects. Nevertheless, these indications are unreliable, and artists can create captivating visual illusions by intentionally altering these cues, which deceive our brains. Although the visual system is highly efficient in normal circumstances, it can be deceived by meticulously designed visuals that question our preconceptions about the essence of reality. Others can impact our views, a complex combination of physical and mental processes and past experiences. Artists, who are always eager and ready to learn, have created thrilling visual illusions that make us reevaluate how we perceive the world

Throughout history, artists have employed linear perspective, colour, and geometric patterns to alter viewers' visual perception and question their comprehension of reality. An essential invention that facilitated the shift from Byzantine art to Baroque and Renaissance to modern style was the implementation of perspective, which greatly influenced how artists manipulated the viewer's perception and understanding of the artist's experience in the sociocultural context. Similarly, in the Op Art movement, artists explore visual perception through geometric patterns, contrasting colours, and different techniques to create the optical illusion of movement, depth, and three-dimensionality on a flat surface. Such an optical illusion combines these elements to create the effect. When we look at this painting technique, it prompts us to think about how we perceive the environment and how we perceive it visually.

This essay will explore the intriguing convergence of perspective and perception in art practice throughout significant art evolution, emphasising how artist Patrick Hughes uses optical illusions to captivate viewers. It will also examine Patrick Hughes's inventive approach, "reverspective," which skillfully manipulates emotions by creating unexpected spatial relationships.

The History of Optical Illusions:

Studying optical illusions in art has a significant and extensive historical foundation. The lasting impact of ancient Greek and Roman artists is particularly remarkable, as they employed techniques such as trompe l'oeil and perspective to achieve an illusionary sense of space in their paintings. These techniques, employing forced perspective to deceive the viewer's perception by making painted things appear genuine and creating the illusion of three-dimensional effects on a flat surface, still inspire contemporary artists. The use of chariosurio techniques, shading, and perspectives in Trompe l'Oeil paintings to give a sense of dimension and realism is a testament to their lasting impact. These classical techniques are traced back to the European Baroque and Rococo periods and were widely used to implement ornamental murals and decorations. (Meyer, 2023) In the modern trends, trompe l'oeil art is prevalent and can be found in many forms, including murals, graffiti, street art and architectural ornamentation.

Adopting a more naturalistic approach and introducing realistic depth, size, volume, and perspective brought about a significant change during the Renaissance period in the 14th century. These artistic principles, integrated with mathematics and science, carry the weight of the Renaissance's influence on art history

Filippo Brunelleschi identified the linear perspective as a significant breakthrough in conveying the appearance of three-dimensional space on a flat surface. These principles were later formalised by the Italian scholar and artist Leon Battista Alberti in his 1435 dissertation, "De Pictura," or "On Painting," thereby cementing his role in the development of art during the Renaissance. (Byzantium and Italian Renaissance Art, n.d.)

Renaissance masters of the linear perspective technique were Raphael, Leonardo da Vinci, Giotto, Masaccio, and Perugino. This gave artists the ability to produce paintings with a true feeling of scale and depth. In the incomplete "Adoration of the Magi" by Leonardo da Vinci, for instance, the artist employed a checkerboard pattern to establish the figures' scale according to their size in relation to the viewer's distance from them. (Byzantium and Italian Renaissance Art, n.d.) During the time many Renaissance artists including Leonardo da Vinci, were linear perspective used logically to create optical illusion in their compositions and also they were quite fascinated with the concept of ‘Anamorphosis’ throughout the period.

Anmorphosis is a Greek word meaning “to transform” and it’s a method to create the distorted image, similar like a reflective mirrored image employs that only resolve into recognizable forms when viewed from a specific angle or it can be curved mirror. The first experiment appears from Leonardo da Vinci’s journal the study of an eye and child’s head and anamorphic images give the impression of reshaping themselves when viewed from the perspective of an eccentric position or at an oblique angle; yet, it is the viewer who is responsible for the optical change.(Faust, 2018)

(Leonardo da Vinci, Anamorphosis: Study of the Eye; on the left, Juvenile Face, in Codex Atlanticus ca. 1478–1518; Milan, Biblioteca Ambrosiana; fol. 98r. )

Hans Holbein the Younger; Jean de Dinteville and Georges de Selve, also known as The Ambassadors; 1533; The National Gallery, London. (Holbein, H., The Ambassadors 1533 The National Gallery, London)

In the similar study Faust (2018) stated that Hans Holbein’s "The Ambassadors" is featured distorted skull which is placed in the bottom centre of the composition. It is intended to be a visual dilemma because the viewer must approach the painting from high on the right side or low on the left side in order to see the form as an accurate portrayal of a human skull. Which is only visible in its entirety when the picture is viewed from the side. The skull is depicted in anamorphic perspective, which was another creation of the Early Renaissance. It is not apparent why Holbein put the skull such a prominent position in this painting, despite the fact that it is obvious that the skull was intended to be a vanitas style.

In the centuries that followed, there was an apparent increase in the use of optical illusions for entertainment and scientific research. M.C. Escher, a renowned graphic designer of the 20th century, gained fame for his remarkable optical illusions. He achieved this by skillfully manipulating perspective and perception. He fascinated spectators with enigmatic artworks that delved into the concepts of relativity and infinity within a single composition, defying conventional knowledge.

Perspective and space are critical elements in Escher's work, as he played with vanishing points, relative size, and overlapping fusing figures to create the illusion of depth on a flat surface. Day and Night (1938) showcases monochromatic avian figures arranged in a pattern on a checkered rural landscape. Many of these photographs lack a clear demarcation between the foreground and background, allowing the observer to see either collection of objects as the foreground freely. (Poole, 2018) Escher's expertise in perspective and perception enabled him to develop a distinctive visual realitivity that combined mathematical concepts with imaginative storytelling. His works still captivate and puzzle spectators today, demonstrating the mind's ability to create and analyse the essence of existence.(Relativity by M. C. Escher, 2010)

(Vasarely, Vega-Nor 1969) In optical illusions, geometric repeated patterns are an indispensable instrument since they enable the production of the sense of motion, depth, and three-dimensionalism on a flat surface. Op Art movement pioneer Victor Vasarely created visually striking deceptions using complex geometric patterns. This method used geometric patterns and colours in direct opposition to one another to generate effects that pulsed and vibrated. The artwork he designed, referred to as "Vega-Nor," is constructed out of a grid of squares that give the sense of expanding and contracting, resulting in a mesmerising effect. A widespread tendency throughout that period characterised the Op art movement: using geometric colours and shapes to create optical illusions.(Buffalo AKG Art Museum, n.d.)

Patrick Hughes and Reverspective

In the contemporary art scenario the renowned British artist Patrick Hughes is well-known for his inventive "reverspective" paintings, which produce arresting optical illusions through tactile structure with multiple vanishing points. Hughes, who was born in Birmingham in 1939, and had a first solo show in 1961 and became well-known for his reverse perspective-based technique.

Hughes experimented with out of wood pieces which he elevated of pyramid structure where he can integrates into ridged panoramas. After which he painted interior scenarios with popular great masters’ works, as well as landscapes and views of the city. It seems as though the sections of the works that are protruding are retreating, while the parts that are receding appear to protrude. This gives the impression that the compositions are moving as the viewers walk by them

Sticking Out Room, 1964, Patrick Hughes "Sticking Out Room," a picture of a room with a interior door seen from above, is one of Hughes's most well-known pieces. The room seems to change shape and perspective as the viewer moves around the picture. The interior door appear to get closer or farther away due to artist’s painted on the top of the 3D truncated pyramid structure. More specifically, the edge of what looks like the far wall with the door is closer to the watcher than the edges of the floor, walls, and ceiling. (Murray McDonald, n.d.)

To show the most common parts of the geometry of perspectives, Hughe show the front, side, and top views of a new piece called “Making Space” artwork (2016) Figure 2, which he has made up of four short pyramids. In both the top and side views, thick lines show the viewer's position, which makes it clear that the cut-off pyramids are sticking out towards them. (Papathomas & Hughes, 2019)

“Making Space” (2016) Figure 2-

Hughes' retrospective paintings reveal to do more than trick the eye; he produces a sense of disorientation and surprise that can be both unsettling and enjoyable by messing with their expectations and questioning what they think they know about perspective.

Hughes achieves this by incorporating recognisable objects and scenes, such as home interiors, mundane objects, popular images, furniture, and landscapes. These elements create a sense of familiarity that initially deceives the viewer into a comforting illusion. However, as the observer navigates the artwork, these familiar components undergo distortion, leading to a feeling of discomfort and perplexity.

Hughes effectively evokes emotions by skillfully employing the formal qualities of perspective, form, colour and composition. The artist's works frequently showcase vibrant and contrasting hues, evoking a strong sense of vigour and activity. The layered panels perceive depth and motion, with components appearing to protrude or retreat into the distance. It fosters a feeling of excitement and curiosity as the observer delves into the artwork and reveals fresh vantage points.

Conclusion:

Throughout the evolution of art practice perspective and perception are powerful tools that artists have long used to construct optical illusions and challenge viewers' assumptions about reality. Some of the most interesting and thought-provoking works of art have always played significant role played in the perspective and perception how we see things. It is factual evident that across all artists has explored from the Renaissance to the present day. During the Renaissance, painters such as Leonardo da Vinci, Leon Battista Alberti, Raphel, Giotto, Hans Holbein and Masaccio explored the use of linear perspective to give the sense of depth and three-dimensionality on a flat surface. They were able to create scenes that looked to fade into space using techniques such as vanishing points, foreshortening, and declining size, luring the observer into an illusionistic realm. This mastery of perspective was a significant departure from the flattened, symbolic style of Byzantine art, Barque and Rococo that preceded it. However, some Renaissance artists like Leonardo da Vinci and Hans Holbein who have experimented with the concept of ‘Anamorphosis’ in their distorted character features in theri work and it can only be seen clearly when viewed from a specific angle

Some of them have chosen to subvert the conventions of perspective to create even more striking optical effects.M.C. Escher's woodcuts and lithographs challenge visual perception. Escher's paintings, such "Relativity" and "Ascending and Descending," use vanishing points and impossible geometries to create surreal sceneries. Escher's art questions viewers' expectations of reality and space, casting doubt on our visual experience. While British artist Patrick Hughes has evolved his own distinctive style termed "reverspective," which questions conventional perspective even more, Vasarely's Op Art paintings include geometric patterns that give the appearance of depth and movement. Hughes' paintings employ a technique where the parts closest to the viewer are put at the greatest distance, while the things farthest away are positioned nearest. The image has a dynamic and mutable nature, which elicits a disconcerting yet compelling impact on the viewer as they move around the artwork.

Hughes's art, like Escher's, tries to control how people feel by interfering with their assumptions. By showing familiar things and scenes, he gives the viewer a false sense of security, broken by the strange distortions of his retrospective method. It creates a feeling of wonder, confusion, and excitement, making people think about what they know about the world. The most important thing about these artists' work is that they are able to use viewpoint and perception to create new and surprising realities. These artists have pushed the limits of what is possible in the visual arts by making viewers question their ideas and interact with the art on a perceptual level. Their work shows how people have always been interested in the secrets of how we see and how much we can explore through art.
