The mathematical laws of perspective were first discovered by the architect Filippo Brunelleschi in the early 15th century. Brunelleschi's work on perspective built on the knowledge of the ancient Greeks and Romans, who had a basic understanding of the concept of the vanishing point. Soon after Brunelleschi's discovery, artists such as Donatello, Masaccio, and Leonardo began to experiment with this technique, applying it to their paintings and sculptures. Perspective in drawing and painting is the art of representing three-dimensional objects and spatial relationships on a two-dimensional plane, giving a realistic appearance to the items drawn in terms of their width, height, and depth.

What You'll Learn
Filippo Brunelleschi's discovery of perspective in the 15th century
Filippo Brunelleschi (1377–1446) is credited with the discovery of linear perspective in art, which revolutionised painting and laid the groundwork for the naturalistic styles of Renaissance art. Brunelleschi, an Italian architect, designer, goldsmith, and sculptor, conducted experiments between 1415 and 1420 to understand how objects, buildings, and landscapes changed shape and how their lines converged when viewed from different angles or distances.
In one of his famous experiments, Brunelleschi used mirrors to sketch the Florence Baptistery in perfect perspective. He mathematically calculated the scale of objects within the painting to make them appear realistic. This discovery of a mathematical system for representing three-dimensional objects and space on a two-dimensional surface was a significant breakthrough.
Brunelleschi's technique involved making the lines in a painting appear to converge at a single fixed point in the distance, known as the vanishing point. This created a convincing sense of depth on a flat surface. He applied this system of perspective to his paintings around 1425, and soon after, artists like Donatello, Masaccio, Lorenzo Ghiberti, and Filippo Lippi adopted this method with remarkable results.
The understanding of linear perspective was not new, as the Greeks and Romans had previously mastered its portrayal in art. However, during the Middle Ages, this knowledge was lost, and artists in Florence struggled to create depth in their paintings. Brunelleschi's rediscovery of linear perspective provided the answer, allowing portraits and paintings to become more realistic, marking a pivotal moment in the Renaissance Era.
The impact of Brunelleschi's discovery extended beyond art. His mathematical technique of linear perspective influenced the rise of modern science and laid the foundation for modern engineering. He is considered the first modern engineer and a founding father of Renaissance architecture.

The vanishing point
When an artist employs linear perspective, they create the illusion of depth by drawing lines that converge at a point on the horizon called the vanishing point. This technique simulates the way our eyes perceive the world and how objects appear to get smaller and converge as they move further away from us. By utilizing this method, artists can create realistic and convincing depictions of space and distance in their artwork.
In a linear perspective drawing or painting, the vanishing point serves as the focal point where parallel lines appear to converge as they recede into the distance. These lines can be horizontal, vertical, or diagonal, and they create a sense of depth and spatial organization in the composition. The placement of the vanishing point can vary, depending on the artist's viewpoint and the desired effect. For example, a higher vanishing point creates a sense of looking down on a scene, while a lower one gives the impression of looking up.
Typically, in a one-point perspective, all the orthogonal lines (lines perpendicular to the picture plane) converge at a single vanishing point. This technique is often used to create a sense of depth when viewing a scene with parallel lines, such as a railway track disappearing into the distance or the interior of a room. However, in more complex scenes or to achieve a more dynamic composition, artists may employ two-point or multi-point perspectives, creating additional vanishing points.
The two-point perspective introduces a second vanishing point, allowing for a more diverse representation of objects and spaces. This technique is particularly useful for cityscapes or architectural scenes where multiple sets of parallel lines need to be represented, such as the sides of buildings converging towards two separate vanishing points on the horizon. Multi-point perspectives take this concept further, utilizing three or more vanishing points to create dynamic and complex compositions with multiple viewpoints.
By manipulating the placement and number of vanishing points, artists can create a sense of movement, depth, and spatial relationships within their artwork. The vanishing point technique not only enhances the realism of a scene but also allows artists to play with perspective and guide the viewer's eye through the composition. This fundamental principle of linear perspective has been a cornerstone of artistic practice for centuries and continues to be an essential tool for artists today.

Linear perspective
The most basic form of linear perspective is one-point perspective, in which all objects with faces parallel to the horizon appear to converge in the distance at a single point on the horizon, known as the vanishing point. To achieve this, the closest face of an object must appear parallel to the horizon. This technique can be used to accurately represent any forward-facing three-dimensional object.
The rules of perspective are based on the optical fact that an object appears N times smaller if it is moved N times further from the eye than the original distance. Thus, objects in a composition are rendered increasingly smaller as they near the vanishing point. The three essential components of the linear perspective system are orthogonals (parallel lines), the horizon line, and the vanishing point.
The first attempts to develop a system of perspective are believed to have begun around the fifth century B.C. in ancient Greece, as part of an interest in illusionism allied to theatrical scenery. However, there is limited evidence to support this claim, and it is suggested that the knowledge of perspective was lost until the 15th century. Italian Renaissance architect Filippo Brunelleschi is credited with devising linear perspective around 1415, and it was later documented by architect and writer Leon Battista Alberti in 1435. Soon after Brunelleschi's demonstrations, artists in Florence and Italy, such as Donatello, Masaccio, and Lorenzo Ghiberti, began incorporating geometrical perspective into their paintings and sculptures.

One-point perspective
The "horizon line" in one-point perspective is not always clearly defined by "sky" and "ground". It can also be the vantage point from which a viewer is observing. For example, the viewer may see an object by looking up at it or perhaps directly down upon it. The object will still be viewed in perspective, but the "horizon line" is not the dividing line between "sky" and "ground" in these situations.
To draw in one-point perspective, you must first define the horizon line and mark the vanishing point. Then, you can plot converging lines and reference points for objects close to the vanishing point. Finally, you can begin measuring and plotting points to create the basic structure of the objects in your drawing.
The use of one-point perspective is often attributed to Renaissance artist Filippo Brunelleschi, who is said to have demonstrated his discovery of perspective in the early 15th century. However, it is believed that attempts to develop a system of perspective began around the 5th century BC in ancient Greece, with philosophers like Anaxagoras and Democritus working out geometric theories of perspective for use with skenographia, or flat panels on a stage to create the illusion of depth.

Chinese artists' use of oblique projection
The laws of perspective, a key concept in the field of art and a tool used to create the illusion of three-dimensional space on a two-dimensional surface, have a rich history that spans multiple cultures and artistic traditions. While the formalization of these laws is often attributed to the Italian Renaissance artist Filippo Brunelleschi, who is known for his groundbreaking work in architecture and perspective drawing, the concept of perspective has been understood and utilized by artists around the world for centuries. One such example can be found in the artistic traditions of ancient China, where artists developed their own unique approach to depicting space and distance, known as "oblique projection."
Chinese artists have a long and illustrious history of employing oblique projection, a unique form of perspective that differs from the more well-known Renaissance linear perspective. Oblique projection is a method of depicting three-dimensional objects and spaces on a two-dimensional surface, and it has been used by Chinese artists for centuries to create stunning works of art that challenge our perceptions of depth and distance. This technique is particularly effective in landscape painting, which is a highly valued genre in Chinese art, often depicting vast and expansive scenes that stretch out into the distance.
The use of oblique projection in Chinese art can be traced back to ancient times, with some of the earliest examples found in Han dynasty tomb paintings, which date back to the 2nd century BCE. These tomb paintings often featured intricate scenes of daily life, with figures and objects depicted in a style that we now recognize as oblique projection. One notable example is the famous "Pingfeng Landscape Tomb Painting" from the Han dynasty, which depicts a landscape with overlapping hills and distant mountains, all depicted using this unique form of perspective.
During the Tang and Song dynasties (618–1279 CE), the use of oblique projection became even more sophisticated, with artists mastering the technique to create incredibly detailed and realistic landscapes. One of the most famous examples from this period is the handscroll "Along the River During the Qingming Festival" by Zhang Zeduan, which depicts a vibrant and bustling cityscape, with buildings, bridges, and figures all depicted in precise oblique projection. This handscroll is often considered a masterpiece of Chinese art and a prime example of the sophisticated use of perspective that had been developed by this time.
The unique approach to perspective used by Chinese artists, with its emphasis on oblique projection, continued to evolve and influence artistic styles even into the modern era. During the Qing dynasty (1644–1912), the use of Western linear perspective began to influence Chinese artists, leading to a fascinating blend of traditional and modern techniques. Some artists even experimented with combining both linear and oblique projection in their works, creating unique and innovative styles that challenged traditional notions of space and form.
In conclusion, the use of oblique projection in Chinese art is a fascinating example of the unique cultural and artistic traditions that have developed independently of Western influences. Chinese artists, through their mastery of oblique projection, have created a rich and distinctive visual language that continues to inspire and influence artists around the world. By understanding and appreciating this unique approach to perspective, we can gain a deeper appreciation of the rich diversity and complexity of global artistic traditions.

Frequently asked questions
The mathematical laws of perspective were first discovered by the architect Filippo Brunelleschi in the early 15th century. He worked out some of the basic principles, including the concept of the vanishing point, which had been known to the Greeks and Romans but was lost.
Perspective in drawing is the art of representing three-dimensional objects on a two-dimensional surface, giving a realistic appearance to the items drawn in terms of their width, height, and depth. When drawing in perspective, the objects in a scene are accurately placed in relation to each other, respecting their distance from the viewer.
Brunelleschi demonstrated his discovery by having people look through a hole in his painting from the backside. Through it, they would see a building, such as the Florence Baptistery. When Brunelleschi lifted a mirror between the building and the painting, the mirror reflected the painting to the observer, allowing them to compare the building and the painting.
