Diego Rivera

1886–1957
Atheist (reported to have said in 1956 that he was a Catholic)

Diego Rivera was the son of a Freemason father and a devout mother, and said he had been an atheist since he was five or six, with no faith to lose. His unbelief was a painter's weapon against priests who blessed the powerful. In 1947 he put it into three words borrowed from Ignacio Ramírez, "Dios no existe", and in June 1948 defended them against an archbishop, the press and a student mob. In April 1956, ill with cancer, he painted them out, and by one report called himself a Catholic. His own explanation spoke of peace, national symbols and historical truth, so whether it was conversion, reconciliation or self-censorship the sources do not settle.

  2. Childhood declaration (his claim) (c. 1892–93, claimed in 1948) — Says he told a church congregation at age six that there was no God; Wolfe says five; Marnham treats it as legend [6][7][8][9]
  3. Public declaration (15 Sept 1947 finished; 1–4 June 1948 defended) — Paints "Dios no existe" on the Prado wall; tells the press "soy ateo" and refuses to remove it; rewrites it the night students erase it [21][22][27][33]

Notes to the timeline (15)
  1. [2] His father, Diego Rivera Acosta, was a "notorious Freemason" and anticlerical; his mother María del Pilar Barrientos, like her own mother, a devout Catholic; they married in 1882 and the marriage lasted 39 years; according to their daughter María the mother gradually adopted most of her husband's opinions — Patrick Marnham, Dreaming with His Eyes Open: A Life of Diego Rivera (New York: Knopf, 1998), chapter 1 only ("Birth of a Fabulist", Guanajuato 1886–1893), as excerpted by the New York Times (archived), saved as texts/marnham-ch1-excerpt.txt; unpaginated. In copyright; read for facts and paraphrased. The rest of the book (IA dreamingwithhise00marn) is lending-only, ch. 1.
  2. [3] The father was inspector of schools, sat on Guanajuato's municipal council, founded a teacher-training school and in 1887 became editor of the liberal paper El Demócrata; Rivera grew up among books in a house with a grand piano — Marnham, Dreaming with His Eyes Open, ch. 1.
  3. [12] No source read shows a period of Christian belief or a crisis of faith in Rivera; the evidence is a Catholic household and baptism, his own claim of childhood atheism, and nothing on religion for 1907–1921. His "faith" mark is therefore inferred, not documented — absence in Marnham ch. 1, Wolfe 1947, Gutiérrez. Not verified.
  4. [6] In Rivera's own later account, aged six, his great-aunt Totota defied his father's rule that he avoid priests and took him to the church of San Diego; he told the saints were wood and plaster, told the congregation to stop giving money to the priest, said a man could not sit on a cloud because of gravity; the priest declared him Satan; he drove the priest out with a candlestick. Marnham notes the story resembles the child Jesus among the elders and the cleansing of the Temple and puts it with Rivera's other childhood legends (the little Scientist, Engineer, General) — Marnham, Dreaming with His Eyes Open, ch. 1.
  5. [7] In June 1948 Rivera told El Universal that he first stated the philosophical opinion that there is no God in public "a los seis años de edad en la iglesia de San Diego, en Guanajuato, mi tierra natal" — Jessica Soto, "Por escribir 'Dios no existe' en un mural, Diego Rivera fue censurado; así fue la polémica," El Universal, 11 April 2020, updated 14 March 2023; reprints El Universal clippings of 3 and 5 June 1948, (reprinting El Universal, 3 June 1948); Cultura Colectiva, 16 April 2020,.

  7.

  10. [27] Rivera's public reply (about 1–2 June 1948): that the archbishop bless the hotel "para que con la ayuda divina" it earn the greatest profits and damn his mural "para que yo me vaya tranquilamente a los infiernos"; and "soy ateo y las religiones me parecen una forma de neurosis colectiva". The Wikipedia article dates this quotation to nine years later; it is from 1948 — Márquez, Sueño de una tarde dominical…, p. 28 (Excélsior, 2 June 1948, p. 13); Soto, "Por escribir 'Dios no existe' en…" (2020).
  11. [33] The same evening about a hundred people leaving a dinner for Fernando Gamboa (Orozco, Dr Atl, O'Gorman, Frida Kahlo, Anguiano and others) came to the hotel; Rivera stood on a chair and, helped by O'Gorman, rewrote the phrase with a pencil and wrote "Dios no existe" in the visitors' book. Time says he "painted the offending words right back" — Márquez, Sueño de una tarde dominical…, p. 32; "Art: Business Is Business," Time, 14 June 1948; Soto, "Por escribir 'Dios no existe' en…" (2020).
  12. [49] With the exhortation of the Catholic poet Carlos Pellicer, Rivera took steps to have the mural shown and "reconciliarse con los católicos"; a letter to Pellicer from the USSR agreeing to erase the phrase was reported by the NYT on 22 January 1956 (Sopitas says 1955) — Márquez, Sueño de una tarde dominical…, p. 35; New York Times, 6 June 1948; 22 January 1956; 15 April 1956: article pages blocked (403); only search-result abstracts seen, saved as texts/nyt-search-snippets.txt.

  13. [51] On 15 April 1956 Rivera climbed the scaffold, replastered and repainted the surface, retouched his child self-portrait and replaced the phrase with "Conferencia en la Academia de Letrán-1836"; the NYT story is dated the same day (15 April 1956, a Sunday), so the paint-out may be a day earlier — Márquez, Sueño de una tarde dominical…, p. 35 (Tiempo, 23 April 1956, p. 7); NYT snippets.
  14. [52] The NYT of 15 April 1956 reports that after painting out the words he came down from the scaffold and told reporters "I am a Catholic" (the Spanish wording used, if any, is not known) — NYT snippets. Abstract is the only source for this, as for the other details in this chapter cited to that source alone.
  15. [54] Archbishop Martínez died on 9 February 1956, so the paint-out and "I am a Catholic" came two months after his death — "Luis María Martínez," English Wikipedia, revision 1375919923 (20 Sept 2026), citing the NYT obituary of 10 Feb 1956, (citing NYT obituary, 10 Feb 1956).

Dios No Existe

At the start of June 1948 the Archbishop of Mexico, Luis María Martínez, was asked to bless the new Hotel del Prado, opposite the Alameda park in Mexico City. In its dining room was a fresco fifteen metres long, Dream of a Sunday Afternoon in the Alameda Central, crowded with figures from Mexico's history. One of them, the nineteenth-century liberal Ignacio Ramírez, held a placard. It read, in the press reports of the time, "Dios no existe": God does not exist. The archbishop refused to bless the hotel.123 Its painter, Diego Rivera, answered that the archbishop should bless the hotel so that, with divine help, it made the greatest possible profits, and damn his mural so that he could go to hell in peace. He did not shelter behind Ramírez, he added; he was an atheist himself, and religions seemed to him a form of collective neurosis.456

This chapter asks where that atheism came from, what it cost, and why, eight years later and ill with cancer, Rivera painted the words out.

A divided house

He was born in Guanajuato on 8 December 1886.7 His father, Diego Rivera Acosta, was a school inspector, a town councillor and the editor of a liberal newspaper, a notorious Freemason and an anticlerical; his mother, like her own mother, was a devout Catholic.89 The household was divided over God from the start. Rivera's twin brother died in infancy, and his mother's grief and religiosity, his biographer Patrick Marnham suggests, shaped the boy.10 The first mark on his timeline stands for a divided house rather than a faith. No source read for this chapter records any period of Christian belief in Rivera, or any crisis of faith.11

His own story of his first declaration came much later. In 1948 he told a newspaper that he had first stated in public the philosophical opinion that there is no God at the age of six, in the church of San Diego in Guanajuato.1213 In the fuller version, a great-aunt took him to the church against his father's wishes, and he told the congregation that the saints were wood and plaster, that they should stop giving money to the priest, and that no man could sit on a cloud because of gravity; the priest called him Satan, and the boy drove him out with a candlestick. Marnham notes how closely the story resembles the boy Jesus among the elders and the cleansing of the Temple, and puts it with Rivera's other childhood legends; Wolfe, for his part, says Rivera claimed his atheism from the age of five.1415 His timeline places a childhood declaration here, but it is his own claim, not a documented event.

The painter

The family moved to Mexico City when he was six or seven; accounts differ on the year and the reason.1617 He entered the Academy of San Carlos at ten and was expelled in 1902 after student riots; a scholarship took him to Madrid in 1907 and Paris in 1909, and he came home in 1921.1819 In the 1920s he painted the frescoes of the Ministry of Education, helped found a revolutionary paper, and went to Moscow as a delegate of the Mexican Communist Party.2021 His biographer Wolfe recalled the fat priests in his murals, taking coins under the Virgin and blessing brutal reaction.22

Ramírez's three words

The words on the placard were not Ramírez's own. As an eighteen-year-old, about 1836, Ramírez had read a paper to the Academia de Letrán in Mexico City, and the poet Guillermo Prieto, who was there, remembered that

leyó con voz segura é insolente el título, que decía: No hay Dios.2324

He read in a sure and insolent voice the title, which said: There is no God. The speech was never published.24 Rivera condensed it, and painted it onto a parchment in Ramírez's hand in the mural he finished on 15 September 1947.252 Wolfe wrote that if the phrase did not represent Ramírez's whole philosophy, it was the one that best represented him in Rivera's spirit.2624 Rivera defended it as the freedom of thought that had made liberal Mexico possible, even if Juárez and Ramírez had not been atheists; Juárez, a historian of the episode notes, was in fact a Catholic.27

June 1948

By 1948 the Church in Mexico had recovered from the anticlerical governments of the 1920s and 1930s, and about nine Mexicans in ten called themselves Catholic.28 The hotel's manager, Rivera said, had known of the phrase since the mural was finished and had asked him to erase it, and he had refused, because the history of Mexico was at stake; the manager said Rivera had promised to change it, and Rivera denied it.29 When the archbishop refused his blessing, he said that this was impossible, a fundamental question affecting the religious feelings of Christendom; he had done nothing, he said, but decline to bless a place where atheism was publicly professed.303132 Time reported Rivera saying he was an atheist, that anyone suffering from religion was sick, but that he was no more an enemy of Catholics than of people suffering from tuberculosis.33 His timeline places his public declaration here.

The press divided. One columnist proposed replacing his words with "I exist, therefore there is God"; another wrote that the essence of what was eternally Mexican was God, while telling Catholics not to boycott the hotel; a consultant to the presidency answered that Rivera had claimed the right to dogmatise about what he did not know.343536 One paper called for "direct action" against the artist.37 On the night of 4 June about a hundred engineering students entered the dining room, beat the guards, and one of them, standing on his brother's shoulders, scraped the phrase off with a hammer.38 That same night Rivera came with a crowd of friends from a dinner, among them Frida Kahlo and the painters Orozco and Dr Atl, stood on a chair and wrote the words back.39 The next night someone erased "no existe," leaving "Dios," and gouged the face of the painted child Rivera with a crowbar.40 The hotel hid the mural behind a screen, which stayed for eight years.41 Students marched with banners reading "God does exist," and a few days later stoned Rivera's house and studio.42 The president, Miguel Alemán, called the affair of no importance.43

Some Catholics condemned the attack. One Catholic columnist, Aquiles Elorduy, reminded his readers that when Ramírez had first read his paper the Academia had accepted him as a member and congratulated him, and argued that a Catholic could simply write "God does exist" beneath the phrase.4445 Sixty years later, one of the brothers who erased it said he had let himself be convinced that the phrase was an attack on Mexico, that his act came from an entirely clerical education, and that he had since become a Marxist.4647

April 1956

In 1953 Time called him one of the most successful publicity seekers in the world, whose formula for making news was to invite attack.4849 Frida Kahlo died in 1954.50 Ill with cancer, he went to the Soviet Union for treatment, and from there, encouraged by the Catholic poet Carlos Pellicer, he wrote that he would erase the phrase.5152 Archbishop Martínez died in February 1956.53 In the middle of April, back in Mexico, Rivera climbed the scaffold, replastered the placard, retouched his child self-portrait, and replaced the three words with "Lecture at the Academia de Letrán, 1836." He said that this respected historical truth, removed pretexts and avoided annoyance; that he felt a need for peace and love, for what unites rather than what divides; and that he loved the Virgin of Guadalupe as a symbol of the nation, the banner of Hidalgo and Zapata.545556575859 The New York Times reported that after coming down from the scaffold he told reporters, "I am a Catholic"; his Spanish words are not known, and the full report was not read for this chapter.60 His timeline places his revision here.

What it meant is an open question. Wolfe found it surprising in a man who had boasted of atheism since the age of five; the historian of the episode calls the whole affair a successful attack that ended by pushing the painter into self-censorship.5961 What he painted in its place was not a profession of faith but a historical fact.

He died on 24 November 1957 and was buried in the Rotunda of Illustrious Persons in Mexico City; whether he received any religious rite is not established.62 The hotel was wrecked in the earthquake of 1985, and the mural, saved, now hangs in its own museum, with the date of Ramírez's lecture where his words had been.63

Did his unbelief change shape?

He said he never had a faith to lose, and the only record of his first atheism is a story he told at sixty-one. For most of his life his unbelief was a painter's weapon, aimed at priests who blessed the powerful. In 1948 he put it in three borrowed words and defended them against an archbishop, the press and a student mob, and for eight years the mural stayed hidden. In 1956, dying, he painted the words out and, by one report, called himself a Catholic, while his own explanation spoke of peace, national symbols and historical truth rather than of God. Whether that was a conversion, a reconciliation or self-censorship, the sources do not settle.

Ignacio Ramírez, whose speech of 1836 gave Rivera his three words, has his own chapter in this book.

leyó con voz segura é insolente el título, que decía: No hay Dios.

Dios no existe, afirmó y demostró experimentalmente, Ignacio Ramírez

Rivera (text painted on the placard in the mural) · El Universal 2020; Cultura Colectiva

Que el Sr. Arzobispo bendiga el Hotel del Prado para que con la ayuda divina realice ese establecimiento las mayores ganancias posibles y que maldiga mi Sueño dominical en la Alameda para que yo me vaya tranquilamente a los infiernos

Rivera, June 1948 · Gutiérrez p. 28 (Excélsior, 2 June 1948, p. 13)

Para afirmar “Dios no existe” no me escudé en don Ignacio Ramírez; soy ateo y las religiones me parecen una forma de neurosis colectiva.

Rivera, June 1948 · Gutiérrez p. 28 (Excélsior, 2 June 1948, p. 13)

Ningún católico tiene por qué ofenderse a causa de la expresión de una opinión filosófica de la cual yo mismo participo y la expuse públicamente por primera vez a los seis años de edad en la iglesia de San Diego, en Guanajuato, mi tierra natal.

Rivera, June 1948 · El Universal 2020 (reprinting El Universal, 3 June 1948); Cultura Colectiva

I am an atheist, that’s true, and I think any individual suffering from religion is sick. But . . . I’m not an enemy of Catholics any more than I am an enemy of those suffering from tuberculosis, myopia, paralysis.

Rivera, reported by Time · Time 1948a, 14 June 1948

necesidad de paz y amor y de lucha por lo que nos une para conseguirlo, no por lo que nos divide

Rivera on the Virgin of Guadalupe, 1956 · Gutiérrez p. 35 (Suárez 1962, p. 67)

I am a Catholic.

Rivera, 14 or 15 April 1956 · NYT, 15 April 1956, "Rivera Expunges 1948 Blasphemy," abstract only (`texts/nyt-search-snippets.txt`)unverified

si la cita no era representativa de la filosofía entera de El Nigromante, sí era la que mejor representaba a este personaje en el espíritu de Diego y en su onírica visión de la historia

Bertram D. Wolfe on Rivera's choice of phrase · Wolfe 1963, p. 304 (1986 Spanish ed.), in Gutiérrez p. 26

Tratándose de un hombre que presumía de que su padre fuese librepensador y él mismo un ateo desde los cinco años de edad

Bertram D. Wolfe · Wolfe 1963, p. 327 (1986 Spanish ed.), in Gutiérrez p. 35 n. 77

Ramírez afirmaba la tesis de que la Humanidad sólo puede avanzar a base de la ayuda mutua, lo que hacía un absurdo de la idea de la ayuda sobrenatural

Rivera, My Art, My Life (Spanish ed.) · Sopitas (second-hand)

La composición son recuerdos de mi vida, de mi niñez y de mi juventud, y cubre de 1895 a 1910

No. Eso no sería posible. Se trata de una cuestión fundamental que afecta a los sentimientos religiosos de la cristianidad.

Archbishop Luis María Martínez, Archbishop of Mexico 1937–1956, asked whether he would bless the hotel if the phrase stayed (3 June 1948) · El Universal 2020 (reprinting El Universal, 3 June 1948)

Yo no he hecho otra que cosa que limitarme a no bendecir un lugar en que se hace fe pública de ateísmo.

Archbishop Martínez, Excélsior, 3 June 1948, p. 17 · Gutiérrez p. 28

Existo, luego hay Dios

"Catalina", Excélsior columnist, proposing the replacement phrase, 2 June 1948 · Gutiérrez p. 29 (Excélsior, 2 June 1948, pp. 6, 19)

Lo mexicano es lo eterno mexicano, y lo eterno mexicano en su esencia más pura es Dios

Carlos Denegri, Excélsior columnist, 4 June 1948 · Gutiérrez p. 29 (Excélsior, 4 June 1948, p. 3)

Me dejé convencer de que esa afirmación era un ataque para México.

Ricardo Ludlow, one of the two students who erased the phrase, speaking in 2009 · Gutiérrez p. 31 (Milenio, 30 Aug 2009)

¡Bendito sea el acto en que, después de escuchar a Ramírez, éste quedó aceptado como miembro de la Academia y felicitado por todos los escritores eminentes de aquella agrupación!

Aquiles Elorduy, Catholic columnist, condemning the attack, Tiempo, 11 June 1948 · Gutiérrez p. 33

one of the most successful publicity seekers in the world today. His formula for making news: invite attack.

Time magazine, 16 February 1953 · Time 1953

Where accounts differ

PointOne accountAnotherHow the page handles it
Rivera's birth date8 Dec 1886, civil record (Marnham ch. 1; Wolfe 1947)13 Dec 1886, baptism certificate as read by Ramón Favela (Marnham ch. 1)Use 8 December; the church record is a footnote.
Age of the childhood declarationSix, in the church of San Diego (Rivera 1948 in El Universal 2020; Marnham)Five, "ateo desde los cinco años" (Wolfe 1963 in Gutiérrez p. 35 n. 77)Say "at five or six, by his own later account"; never present as fact.
Whether the church scene happened, and whether it ended the Guanajuato yearsRivera: it may have caused the move; family: "a public attack by the clergy" (Marnham)Marnham: money after the governor's death in 1893; legends resemble Christ storiesPresent as Rivera's legend.
Year the family left Guanajuato1892 (Wolfe 1947)Late 1893 (Marnham)Say "when he was six or seven".
What Rivera said in 1948Spanish: "soy ateo y las religiones me parecen una forma de neurosis colectiva" (Gutiérrez p. 28)Time's English: "any individual suffering from religion is sick" (Time 1948a); the article of Wikipedia dates the Spanish line to 1956Use the Spanish in his own words with the date; mention that English-language papers paraphrased it more harshly.
What Rivera asked of the archbishop"las mayores ganancias posibles" (Gutiérrez)"la mayor cantidad de dólares" (El Universal 2020)Quote only the sarcasm both share: bless the hotel, damn the mural.
The placard's wording"Dios no existe" (Gutiérrez; Time; Wikipedia)"Dios no existe, afirmó y demostró experimentalmente, Ignacio Ramírez" (El Universal 2020; Cultura Colectiva; Rancho Las Voces)Say the full line is Rivera's condensation; note Ramírez's own wording [Q1].
Date and wording of Ramírez's speech1836; "No hay Dios" as the title (Prieto)1836 or 1837, thesis "No hay Dios; los seres de la Naturaleza se sostienen por sí mismos" (episode 36 sheet; Altamirano)Say "as a young man, about 1836".
Who restored the phrase and howRivera wrote it again with a pencil (Gutiérrez p. 32; El Universal 2020: wet pencil)"painted the offending words right back" (Time 1948a)Say he wrote it back the same night.
The raid"cerca de cien estudiantes" with a hammer (Gutiérrez; UNAM bulletin snippet)Ludlow: "five or six" went in; Time: "table knives"Give the hundred as the newspaper figure and Ludlow's recollection as his.
The second damageCrowbar, night of 5 June (Gutiérrez); three scratches (Time 1948b)Rivera: a government carpenter forced to do it (My Art, My Life per Gutiérrez)Say "someone damaged it again"; give Rivera's accusation as his.
Who stood behind the raidConejos and the UNAM rector fight; the archbishop's involvement "no tenemos pruebas" (Gutiérrez)Rivera: manager Torres Rivas and Alemán's secretary de la Selva (Gutiérrez p. 32)Present each as a claim.
Name of the dining roomSalón Versalles (Gutiérrez; WP en)"Salón de los Candiles" (El Universal 2020)Use "the hotel's dining room".
Date of the paint-out15 April 1956 (Gutiérrez p. 35)NYT dated 15 April 1956 (a Sunday) already reports it done (NYT abstract)Say "in the middle of April 1956".
When Rivera agreed to eraseLetter to Pellicer reported 22 Jan 1956 (NYT abstract); steps taken as he fell ill (Gutiérrez)1955, "durante un viaje en la Unión Soviética" (Sopitas)Say "in a letter from Moscow, around the turn of 1955 and 1956".
What the 1956 revision meantA man ill with cancer seeking peace, who told reporters "I am a Catholic" (NYT abstract; Rivera's own explanation, Q7, Q8)Self-censorship under pressure (Gutiérrez p. 35); "surprising" for a lifelong anticlerical (Wolfe); the replacement text restores a historical, not a theological, claimTell it as an open question: what he said, what he painted, and what his own explanation does and does not claim.
How long the mural was hiddenEight years, 1948–1956 (Gutiérrez; NYT abstract)"Nine years" (Wikipedia)Say eight years.
Roster datingPainted 1946–47, finished 15 Sept 1947; scandal June 1948 (Gutiérrez p. 28)"1947 mural... national scandal" (roster)The script should give 1947 for the painting and 1948 for the scandal.
