Leon Battista Alberti (Italian: [leombatˈtista alˈbɛɾti]; born February 14, 1404; died April 25, 1472) was an Italian Renaissance writer, artist, architect, poet, priest, language expert, thinker, and code maker. He is often seen as a person who had knowledge in many areas. Alberti is known as the beginning of European code making, a title he shares with Johannes Trithemius.

Although Alberti is best known as an architect, he worked in many other areas. James Beck said that focusing on one area of Alberti’s work does not help explain his wide range of achievements in art. Alberti was also a mathematician and made important discoveries in that field. Two famous buildings he designed are the churches of San Sebastiano (1460) and Sant'Andrea (1472), both located in Mantua.

Alberti’s life was described in Giorgio Vasari’s book Lives of the Most Excellent Painters, Sculptors, and Architects.

Biography

Leon Battista Alberti was born in 1404 in Genoa. His mother was Bianca Fieschi. His father, Lorenzo di Benedetto Alberti, was a wealthy Florentine who was forced to leave his city but returned in 1428. Alberti attended a boarding school in Padua and later studied law at Bologna. He lived in Florence for a time and then traveled to Rome in 1431, where he joined the clergy and worked for the Pope’s court. During this time, he studied ancient ruins, which sparked his interest in architecture and influenced the buildings he designed.

Alberti was believed to be tall, strong, and skilled in horseback riding. He was talented in many areas and showed writing ability as a child. By age 20, he had written a play that was mistaken for a real piece of ancient literature. In 1435, he began his first major work, Della pittura, which explored painting techniques, perspective, and color, inspired by the art of Florence in the 1400s.

In 1438, Alberti focused more on architecture. He was encouraged by Marchese Leonello d'Este of Ferrara, for whom he built a small arch to support an equestrian statue of Leonello’s father. In 1447, Alberti became an architectural advisor to Pope Nicholas V and worked on projects at the Vatican.

His first major architectural project was the façade of the Rucellai Palace in Florence in 1446. In 1450, he redesigned the Gothic church of San Francesco in Rimini into a memorial chapel, the Tempio Malatestiano. In Florence, he designed the upper parts of the façade for the Dominican church of Santa Maria Novella, connecting the main part of the church to the lower sections with two decorative scrolls. This design solved a visual problem and influenced church architecture for centuries. In 1452, he completed De re aedificatoria, a book about architecture based on the work of Vitruvius and inspired by ancient Roman buildings. The book was not published until 1485. In 1464, he wrote De statua, a less influential work about sculpture. Alberti’s only known sculpture is a self-portrait medallion, sometimes credited to Pisanello.

Alberti designed two churches in Mantua: San Sebastiano, which was never completed, and the Basilica of Sant’Andrea. The design for the latter was completed in 1471, a year before Alberti’s death. Construction continued after his death, and the church is considered his most important work.

As an artist, Alberti was different from ordinary craftsmen trained in workshops. He was a humanist who studied Aristotle and Plotinus. He was part of a growing group of intellectuals and artists supported by noble courts. As a member of a noble family and part of the Roman curia, Alberti had special status. He was welcomed at the Este court in Ferrara and spent time with Federico III da Montefeltro, a clever military leader who funded artists. Alberti planned to dedicate his architecture book to Montefeltro.

Among Alberti’s other works were an essay on cryptography, De componendis cifris, and the first Italian grammar. He worked with the Florentine cosmographer Paolo Toscanelli on astronomy, a science closely related to geography. He also wrote a short Latin work on geography, Descriptio urbis Romae (The Panorama of the City of Rome). Just before his death, he completed De iciarchia (On Ruling the Household), a dialogue about Florence during the Medici rule.

Alberti joined the clergy and never married. He loved animals and had a pet dog, a mongrel, about whom he wrote a tribute called Canis. Vasari described Alberti as “an admirable citizen, a man of culture… a friend of talented men, open and courteous with everyone. He always lived honorably and like the gentleman he was.” Alberti died in Rome on April 25, 1472, at the age of 68.

Publications

Leon Battista Alberti believed that mathematics was the basis of both art and science. In his book Della Pittura (On Painting), which he wrote for the artist Filippo Brunelleschi, Alberti explained, "To make my ideas clear, I will take what mathematicians have studied, since these are important for painting."

In Della Pittura, Alberti used the study of light and vision from classical science to help artists create realistic images. He understood the science of his time, including the work of the Arab scholar Alhazen, whose book The Book of Optics influenced European thinkers like Roger Bacon, John Peckham, and Witelo. Alberti also studied the writings of Lorenzo Ghiberti, another artist.

In both Della Pittura and De statua (On Sculpture), Alberti wrote that artists should learn from nature. He believed that painters and sculptors should create works that look like real things from nature. However, Alberti did not mean that artists should copy nature exactly. Instead, he said artists should focus on beauty, because "in painting, beauty is as important as it is necessary." Alberti believed that a perfect artwork is made of parts that fit together perfectly, so that nothing can be added or removed without harming its beauty. He described beauty as the balance between all parts of a work, and he connected this idea to the ancient Greek thinker Pythagoras, who believed that harmony could be found in numbers and proportions.

In Rome, Alberti studied ancient buildings and ruins. His book De re aedificatoria (On the Art of Building), written in 1452, was inspired by the writings of the Roman architect Vitruvius. Alberti’s book was the first major Renaissance work on architecture. It covered topics like city planning, engineering, and the beauty of buildings. The book was expensive and not published until 1485, but it became an important guide for architects. Alberti wrote it not only for builders but also for people interested in the arts. The book was first published in Latin, then in Italian in 1546 and 1550. Pope Nicholas V, who Alberti dedicated the book to, wanted to rebuild Rome but only completed a small part of his plan. Through his writing, Alberti shared the ideas of the Renaissance with others.

Alberti also wrote I Libri della famiglia, which discussed education, marriage, and managing a household. He wrote it in the Tuscan dialect and it was not published until 1843. Like the writer Erasmus, Alberti believed that education needed to change. He argued that young children should learn to read as early as possible. He gave the book to his family to read, but he later said that some relatives laughed at his ideas.

Alberti’s comedy Momus, written between 1443 and 1450, was a play about the Greek gods. Some believe the character Jupiter in the play represents Pope Eugenius IV or Pope Nicholas V. Alberti based many characters on the Greek writer Lucian. The title Momus comes from the Greek word for "blame" or "criticism." In the story, Momus, the god of mockery, is cast out of heaven and punished. The gods also visit Earth but return to heaven after a storm damages Jupiter’s nose.

Architectural works

Alberti focused more on design than on engineering. Most of his major projects were not built. As a designer and student of Vitruvius and ancient Roman architecture, he studied column and lintel-based buildings, focusing on their appearance rather than their structure. He correctly used the Classical orders, unlike his contemporary, Brunelleschi, who used Classical columns and pilasters in a more flexible way. Alberti thought about how architecture affects society and paid attention to city layouts. This is shown by his addition of a continuous bench at the Rucellai Palace, placed at the level of the basement. Alberti introduced the idea of street hierarchy, with wide main streets connected to narrower secondary streets and buildings of the same height.

In Rome, Alberti worked for Pope Nicholas V on restoring the Roman aqueduct of Acqua Vergine. The aqueduct emptied into a simple basin Alberti designed, which was later replaced by the Baroque Trevi Fountain.

Some researchers believe the Villa Medici in Fiesole might have been designed by Alberti instead of Michelozzo. This hilltop home, commissioned by Giovanni de' Medici, Cosimo il Vecchio’s second son, offers a view of the city. It is sometimes considered the first example of a Renaissance villa, based on Alberti’s writings about country homes called "villa suburbana." The building later inspired many similar projects from the late 15th century.

The Tempio Malatestiano in Rimini (1447, 1453–60) was the rebuilding of a Gothic church. Its façade, with its lively design, was left unfinished.

The design of the Palazzo Rucellai’s façade (1446–51) was one of several projects commissioned by the Rucellai family. The design uses a grid of shallow pilasters and cornices in a classical style over rough stone walls, topped by a heavy cornice. The inner courtyard has Corinthian columns. The palace introduced the use of classical building elements in civic buildings in Florence and became very influential. The work was completed by Bernardo Rossellino.

At Santa Maria Novella in Florence (1448–70), Alberti designed the upper façade. This was a difficult task because the lower level already had three doorways and six Gothic niches with tombs and colorful marble, like those in San Miniato al Monte and the Baptistery of Florence. Alberti’s design included an existing round window. He added classical features around the portico and spread the colorful marble across the entire façade, using classical proportions and elements such as pilasters, cornices, and a classical-style pediment decorated with a sunburst made of small tiles. A notable feature of this church is how Alberti visually connected the central nave and the lower side aisles using two large scrolls, which later became common in church façades.

Alberti is believed to have advised the design of Piazza Pio II in Pienza. The village, previously called Corsignano, was redesigned starting around 1459. It was the birthplace of Aeneas Silvius Piccolomini, Pope Pius II, who employed Alberti. Pius II wanted the village to reflect his importance as a pope.

The piazza is shaped like a trapezoid and includes four buildings, with the focus on Pienza Cathedral and passages opening to a view of the landscape. The main residence, Palazzo Piccolomini, is on the western side. It has three stories with pilasters and entablature courses, and twin-lighted cross windows in each bay. This structure is similar to Alberti’s Palazzo Rucellai in Florence and later palaces. The palace’s internal courtyard is notable. The southern side of the palace has a loggia on all three floors overlooking an enclosed Italian Renaissance garden with modifications and views of the distant Val d'Orcia and Mount Amiata. Below the garden is a vaulted stable with stalls for 100 horses. The design transformed the town’s center, including a palace for the pope, a church, a town hall, and a building for bishops. Pienza is considered an early example of Renaissance urban planning.

The Basilica of Sant’Andrea in Mantua was started in 1471, the year before Alberti’s death. It was completed and is his most important work using the triumphal arch motif for both the façade and interior. This design influenced many later works. Alberti saw the role of an architect as a designer, unlike Brunelleschi, who focused on construction, leaving practical details to builders and others.

Painting

Giorgio Vasari, who believed that art reached its highest point in Michelangelo, focused on Alberti's intellectual work rather than his artistic skills. Vasari wrote, "Alberti spent time learning about the world and studying how ancient buildings were built. Most of all, he focused on writing instead of creating art." In his book On Painting, Alberti used the term "We Painters," but as a painter or sculptor, he was more of an amateur. Vasari noted, "Alberti did not create any important or beautiful paintings. The few paintings that still exist are not perfect, but this is not surprising because he spent more time studying than making art." Jacob Burckhardt, in The Civilization of the Renaissance in Italy, described Alberti as a person with many talents. He compared Leonardo da Vinci to Alberti, saying, "Leonardo was like a master, while Alberti was like a beginner. If Vasari had written about Alberti like Burckhardt did, people might better understand Alberti's full abilities." Alberti is believed to appear in Mantegna's famous frescoes in the Camera degli Sposi as an older man in dark red clothing, whispering to Ludovico Gonzaga, the ruler of Mantua. In Alberti's self-portrait, a large plaque, he is dressed as a Roman. To the left of his face is a winged eye. On the back of the plaque is a question from Virgil's Eclogues: "What then? (Quid tum?) 'So what, if Amyntas is dark? Violets are black, and hyacinths are black.'"

Contributions and cultural influence

Leon Battista Alberti made many important contributions to different areas of study:

• Alberti created a theory called "historia." In his book De pictura (1435), he explained how people, animals, and buildings in a painting can work together to create a sense of harmony and beauty. This book was the first scientific study of perspective, a technique used to make art look three-dimensional. A version of De pictura in Italian, called Della pittura, was published in 1436. The Latin version was given to Alberti’s patron, Gianfrancesco Gonzaga of Mantua. Alberti also wrote about sculpture in De statua.

• Alberti wrote books about art that introduced new ideas about how artists should create works. He used his knowledge of artists like Brunelleschi, Donatello, and Ghiberti to help other artists learn practical skills during the Renaissance.

• Alberti introduced the "Albertian Window," a concept in De Pictura that helped artists develop linear perspective, a technique still used today in fields like architecture and computer graphics. Some modern art styles, like Cubism, may have been influenced by Alberti’s ideas. However, the connection between Alberti’s work and later scientific discoveries, such as Albert Einstein’s theories, is not certain.

• Alberti wrote a famous book on architecture called De re aedificatoria. By the 1500s, it had been translated into Italian, French, Spanish, and English. A version in English was published in the 1700s by Giacomo Leoni. More recent translations are available today.

• Alberti’s books on painting and architecture are considered important early works that helped shape Renaissance art. However, it is unclear how much his ideas directly influenced artists during his time. His work The Calumny of Apelles inspired artists like Botticelli and Signorelli. Other artists, such as Mantegna and Piero della Francesca, followed Alberti’s artistic ideals, but it is hard to say how much Alberti’s ideas or the trends of the time influenced these changes.

• Alberti was skilled at writing Latin poetry. At age 20, he wrote a comedy called Philodoxius, which later fooled Aldus Manutius, a famous editor, into believing it was written by someone else.

• Alberti may have written or designed the woodcut illustrations for a strange fantasy novel called Hypnerotomachia Poliphili.

• Alberti wrote many other books, including Philodoxus, De commodis litterarum atque incommodis, Intercoenales, Della famiglia, Vita S. Potiti, De iure, Theogenius, Profugorium ab aerumna, Momus, and De Iciarchia. These works were published in Venice in 1586 by Cosimo Bartoli.

• Alberti was a skilled cryptographer and invented the first polyalphabetic cipher, now called the Alberti cipher. He also created a tool called the Cipher Disk to help with encryption. His work was a major advancement in cryptography, though it was not widely used for centuries. A historian named David Kahn called Alberti the "Father of Western Cryptography" because of his contributions to the field.

• In a short autobiography written around 1438, Alberti claimed he could "stand with his feet together and spring over a man’s head." He also said he was good at physical activities, such as jumping over people and throwing coins high into the air. These claims were recorded by Antonio Muratori in the 1700s. Many Renaissance figures exaggerated their abilities, and Alberti’s claims should be understood in that context.

• Alberti claimed to be a skilled musician and organist, but there is no proof to support this. Some people in his time pretended to be skilled in music, as noted in a song by Francesco Landini. Alberti held a position as a canon in Florence, which may have given him time to study music, but this is not certain.

• Alberti worked with Paolo Toscanelli, an astronomer and cartographer, on mapmaking.

• Alberti believed that art should imitate nature, selecting its most beautiful parts. He wrote, "Take from nature what you are going to paint, and choose the most beautiful and worthy things."

• Architectural historian Borsi noted that Alberti’s ideas about architecture continue to influence modern and contemporary architects. For example, the styles of Frank Lloyd Wright, Le Corbusier, and Louis Kahn show elements that may be linked to Alberti’s work.

In popular culture

• Leon Battista Alberti is a main character in Roberto Rossellini’s three-part TV series The Age of the Medici (1973). The third and final part, Leon Battista Alberti: Humanism, focuses on him, his works (such as Santa Maria Novella), and his ideas. He is played by Italian actor Virginio Gazzolo.
• He is mentioned in the 1994 film Renaissance Man (also called Army Intelligence), starring Danny DeVito.
• He is mentioned in the 2004 book The Rule of Four by Ian Caldwell and Dustin Thomason.
• He is mentioned in the board game Alma Mater, where he appears on cards with special powers.
• Dr. Peter Weller, an actor known for his role in the 1987 film RoboCop and for appearing in over seventy films and TV shows, wrote a book titled Leon Battista Alberti in Exile: Tracing the Path to the First Modern Book on Painting. The book was published by Cambridge University Press on March 6, 2025. In this work, Weller argues that Alberti’s important book De pictura was greatly influenced by his time in exile in cities like Padua, Bologna, and Rome, not only by his later return to Florence. Weller claims that Alberti’s humanist education, math training, and exposure to different art traditions in these cities helped him combine humanism and art theory in a way that raised painting to the level of a liberal art.
• ALBERTI ROMANI, a modern-day expert in many fields and a jazz composer, was born in the city of La Romana almost exactly 500 years after Alberti’s death.
