Mexican Muralists: How Los Tres Grandes Remade American Art

Diego Rivera (1886-1957) was the most Mexicanist, with his disciples coining much Mexican iconography. As a Communist Party member, he believed in proletarian revolution and material progress. He studied indigenous art and organized the first Mexican popular art exhibition in 1922. For Rivera, painting is creation, not reproduction—speaking truth and interpreting it. He combined love for indigenous Mexico with enthusiasm for industrialized North America, seeking union between both poles. He maximized architectural space integration, using cubic spaces to narrate history as ascending spirals. José Clemente Orozco (1883-1949) viewed freedom as supreme value, maintaining critical distance from political parties. He believed creation starts with conflict, and themes are means, not ends. His tragic aesthetic stems from the impossibility of knowing the absolute. He proclaimed American identity, seeking a new American art. David Alfaro Siqueiros (1896-1974) participated in the 1911 student strike and revolution. Like Rivera, he shared optimism about the future and interest in the proletariat, exalting the revolution with didactic intent. Unlike Orozco, he proposed class struggle, rejected individualism, and exalted collective creation. He proclaimed the aesthetic of the machine and praised speed, coinciding with Italian futurism principles. His technical innovations included using air guns and metallic surfaces, introducing sculpinture, and experimenting with exterior mural techniques. Mexican muralism emerged from a desire to educate senses, taste, intellect, and spirit of individuals and popular populations by painting on public walls where access was casual and free. It created a national school with universal dimensions, animated by humanistic nationalism encouraging all inhabitants regardless of social position.

Diego Rivera, José Clemente Orozco, and David Alfaro Siqueiros were three of the most important Mexican muralists of the 20th century. They are collectively known as the Mexican Muralists. All three were Mexican artists who created large-scale public murals depicting Mexican history, culture, and social issues. They were also friends and contemporaries, though not all three married Frida Kahlo (only Rivera did).

The murals of Diego Rivera, David Alfaro Siqueiros, and José Clemente Orozco (1922-1930s) served as powerful visual narratives documenting Mexico's turbulent history from Spanish conquest through the Revolution (1910-1920), using art to construct national identity and critique political corruption, with each artist developing unique styles reflecting their distinct political philosophies—Rivera's communist sympathies, Siqueiros' revolutionary populism, and Orozco's moral skepticism.

Mexican muralism was defined by three major artists with distinct approaches. Rivera created accessible, monumental works encoding Marxist ideology with workers as heroes. Orozco offered critical perspectives, depicting troubling aspects of Mexican history including human struggles even among indigenous peoples and during revolutionary times. Siqueiros was the most flamboyant, employing dramatic, simplified iconography that created powerful visual assaults on poverty and suffering. Together, these artists developed a comprehensive visual language for communicating revolutionary themes, each contributing unique dimensions to the movement's legacy.

The three greats (Los Tres Grandes)—Diego Rivera, José Clemente Orozco, and David Alfaro Siqueiros—were commissioned by post-revolutionary Mexico to create educational murals rebuilding national identity. Rivera, influenced by European Cubism in Paris, brought narrative storytelling to public art. Orozco invented spray paint and created three-dimensional murals that enveloped buildings, shocking audiences with unflinching critiques of both government and revolutionary violence. Siqueiros, politically radical, attempted to assassinate Trotsky. Together, they established muralism as a powerful tool for social commentary, influencing Jackson Pollock and transforming American art.

True fresco is a specific medium practiced for thousands of years, distinct from wall paintings, urban murals, or Egyptian tomb paintings. Leonardo da Vinci rejected fresco despite possessing all necessary skills because it is extremely constrictive—requiring intricate advance planning and rapid execution on wet plaster with no room for correction. The medium relies on calcium carbonate (lime) that transforms through slaking (heating and water absorption), creating a chemical bond between pigment and plaster. This process, taking months to years historically, produces a durable, luminous surface where pigment becomes part of the wall itself.

Fresco painting involves applying pigments to wet plaster (buon fresco), while secco fresco is applied to dry plaster. The church contains both techniques, with the Battle of Bistrița frescoes painted on wet plaster for durability. The five-stage fresco narrative depicts King Solomon's 1068 battle against Pechenegs, showing the Hungarian army departing, the battle, a Pecheneg stealing a woman, Prince Laszlo's death, and the woman mourning. This same scene appears in over 40 churches across Transylvania. The frescoes also include symbolic elements like halos around saintly figures, demonstrating how religious art combined historical narrative with spiritual symbolism.

Fresco painting is an artistic technique where paint is applied directly to wet plaster as the wall is being finished and built. The final layer of plaster takes exactly one day to dry, during which time artists can only paint on it. Once this layer dries completely, no further painting can be done. This technique explains why fresco paintings have maintained their vibrant colors for centuries, as the paint becomes chemically bonded to the plaster.

Fresco painting is a traditional technique where artists paint directly onto wet lime plaster, allowing the pigment to bond with the plaster as it dries. The process involves preparing lime plaster by mixing slaked lime with water and letting it rest for about a week, then applying it to a wooden board mixed with coarse sand and two-component epoxy resin. After the plaster dries for 24 hours, the design is transferred using tracing paper and a tracing wheel. The painting must be done while the plaster is still wet, using dry mineral pigments mixed with water, as the plaster develops a crust once dry that prevents pigment application.

Fresco painting is an ancient artistic technique where pigments mixed with water are applied to fresh, wet lime plaster, creating a permanent bond with the wall; the term 'fresco' comes from the Italian word for 'fresh,' and true fresco (buon fresco) requires working within a narrow time window of about 7-9 hours per section (called 'giata') before the plaster dries, while secco fresco uses dry plaster with binders for easier corrections but less durability; this technique has been used since at least 2000 BCE and remains relevant today, with artists from Giotto to modern creators continuing to use it for its unique combination of artistic expression and architectural integration.

This section examines how the Great Depression transformed American art through government intervention and the emergence of social realism. After the 1929 crash, Franklin Roosevelt took office with emotional commitment against materialism and capitalist financial system, declaring 'the money changes have fled from their high seats in the temple of civilization we may now restore that Temple to the ancient truth.' He compared the situation to war, requesting executive power to wage emergency against crisis. During his first 100 days, he established new government agencies including the Works Progress Administration (WPA), a job creation authority funding anticyclical construction activities and visual artists, writers, and theater professionals. Mexican mural painting was regarded as model for public promotion of visual art promising renewal of American painting and true American Renaissance. Artists participated in three movements: conservative regionalists ('paint American'), leftist politically active socialist realists, and modernists. William H. Johnson received commissions for monumental murals depicting industrial construction, while Philip Evergood painted scenes of class struggle including the Memorial Day Massacre. Evergood's 'Dance Marathon' depicted couples dancing for days until collapsing, showing dancers contorted and overstrained with grotesque clothing, representing moral critique of sensation-seeking entertainment exploiting unemployed.

The Works Progress Administration (WPA) was a New Deal program that employed artists during the Great Depression, paying $96 per month and requiring artists to submit two oil paintings and two watercolors or four lithographs. The program was described as saving many artists from starvation and as contributing significantly to American culture. Public art, including murals, played an important role in documenting and interpreting the Great Depression. The video describes how social realism became a dominant artistic movement, focusing on capturing everyday life and telling the story of the average citizen. The CO Tower in San Francisco was the site of a pilot program that employed 26 artists to create murals, paving the way for public art to spread throughout the country.

Social realism emerged as an international art movement responding to industrialization and urban poverty, tracing back to 19th-century European realism including Courbet and Millet. The Ashcan School (1900s) in America, led by Robert Henri and featuring George Bellows and John Sloan, documented New York's social realities. During the Great Depression, social realism flourished through New Deal programs: the FSA employed photographers like Dorothea Lange and Walker Evans to document rural poverty (producing 80,000+ images), while the WPA employed millions of artists. Key figures included Edward Hopper, Thomas Hart Benton, Jacob Lawrence, and Romare Bearden, who recorded contemporary life with dispassionate realism, creating a bridge between European traditions and American social consciousness.

During the Great Depression, the U.S. federal government sponsored extensive art programs through the New Deal (1933-1945) to provide relief, recovery, and reform, employing approximately 8.5 million Americans through the Works Progress Administration (WPA) and creating thousands of artworks including 2,500 murals, 18,000 sculptures, and 100,000 paintings. These projects represented America's cultural pluralism and regional diversity rather than promoting a monolithic national narrative, while simultaneously affirming core American values of hard work, perseverance, and community. The New Deal art programs were inclusive, employing women (41% of WPA artists), artists of color, and diverse stylistic approaches from social realism to abstract expressionism, thereby democratizing American art and establishing a foundation for mid-20th century American art movements.

The WPA employed artists during the Depression, paying $96 monthly for creative work. This saved many from starvation while producing significant public art. The Coit Tower murals in San Francisco pioneered social realism, depicting everyday life rather than elite subjects. One mural was deemed 'misery laden and depressing' and whitewashed, illustrating tensions between artistic truth-telling and public sensibilities.
