His large frescoes helped establish the Mexican mural movement in Mexican art.  Between 1922 and 1953, Rivera painted murals among others in Mexico City, Chapingo, Cuernavaca, San Francisco, Detroit, and New York City.  In 1931, a retrospective exhibition of his works was held at the Museum of Modern Art in New York.  Rivera had a volatile marriage with fellow Mexican artist Frida Kahlo.

It received inspiration from the Aum Shinrikyo cult and their Tokyo subway sarin attack of 1995.  The English translation, by Philip Gabriel, first appeared in 2003.

A Personal Matter (Japanese: 個人的な体験 ; Kojinteki na taiken) is a novel by Japanese writer Kenzaburō Ōe.  Written in 1964, the novel is semi-autobiographical and dark in tone.

Nip the Buds, Shoot the Kids (芽むしり仔撃ち "Memushiri kouchi "; also known as "Pluck the Bud and Destroy the Offspring") is a 1958 novel by Japanese author Kenzaburō Ōe.  It is Ōe's first novel, written when he was 23 years old. The Game of Contemporaneity or dojidai gemu (同時代ゲーム) is a 1979 novel by the Japanese writer Kenzaburō Ōe.  "The Game of Contemporaneity" was originally inspired on Diego Rivera’s mural 'Dream on a Sunday Afternoon in the Central Alameda'.  Oe's approach to history and story-telling, like in the mural, exposes the themes of simultaneity, ambiguity and thus complexity.  The story centres itself around the alternative world of the dissident samurai, as opposed to that of the Emperor.  The samurai turn into demons after being chased into the forest.  The story of the village serves as a microcosmic representation of the history of the nation as a whole.  It has its own creation myth and fertility goddess, as well as having a composite healer/trickster called: The One Who Destroys.  Although the novel exposes the themes of marginalisation and outsiderhood, it also provides hope for a new beginning.  This emphasizes the central theme of the novel: simultaneous ambiguity, in the amalgamation of past and present, fact and dream, as well as history and myth.  Oe uses satire, parody and black humour to describe the many deeds and events of the samurai.  This culminates in the Fifty-Day War, in which the samurai and the imperial army battle one another, with The One Who Destroys leading the battle against The No-Name Captain of the imperial guard.  It ends in the samurai surrendering to avoid the destruction of the forest (mori).  The word 'mori' in itself is ambivalent in that in Japanese it conjures an image of regeneration or rebirth and in Latin that of death.
