The last meal that Jesus shared with his disciples is described in all four canonical Gospels (, , and ).
This meal later became known as the Last Supper.
The Last Supper was likely a retelling of the events of the last meal of Jesus among the early Christian community, and became a ritual which recounted that meal.
Paul's First Epistle to the Corinthians, which was likely written before the Gospels, includes a reference to the Last Supper but emphasizes the theological basis rather than giving a detailed description of the event or its background. 
In 1972 Edelson used an image of Leonardo da Vinci’s mural to create "Some Living Women Artists / Last Supper."
She used collage to add notable women artist's heads of the men in Da Vinci's painting, which quickly became "one of the most iconic images of the Feminist Art movement."
John the Baptist's head was covered by Nancy Graves and Christ by Georgia O'Keeffe.
It confronted the role that society and religion has had in women's "subordination."
"Proposals for: Memorials to the 9,000,000 Women Burned as Witches in the Christian Era," a 1977 performance piece, had the same objective.
New York's Museum of Modern Art has the original work made by Edelson.  
For the 24th annual event held September 30, 2007, the official poster artwork was a photo featuring well-known LGBT and BDSM community members in festive and fetish attire including Sister Roma "as players in an innovative version of the culturally iconographic" "The Last Supper" by Leonardo da Vinci, complete with table draped with the Leather Pride flag and "cluttered with sex toys, whips, and various (BDSM) restraints".
The image by FredAlert was used on the official event guide and produced as collector's posters that were displayed throughout the city as advertising for the event.
Some conservative religious groups criticized the image as anti-Christian and blasphemous, although media outlets noted that parodies and homages of the Last Supper painting like Renée Cox's "Yo Mama's Last Supper" are numerous, including ones by "The Simpsons", "The Sopranos", Phish, "That '70s Show", Robert Altman (in the film "MASH") and the Boston Red Sox.
Chris Glaser, a gay clergyman and interim senior pastor at San Francisco's Metropolitan Community Church agreed that "they are just having fun" with both the painting and the notion of 'San Francisco values,' stating he thought it was "tastefully and cleverly done.
"From a press release about the poster, Andy Copper, Board President of Folsom Street Events, a non-profit organization, stated, "There is no intention to be particularly pro-religion or anti-religion with this poster; the image is intended only to be reminiscent of the ‘Last Supper’ painting.
It is a distinctive representation of diversity with women and men, people of all colors and sexual orientations."
and "We hope that people will enjoy the artistry for what it is - nothing more or less.
Many people choose to speculate on deeper meanings.
The irony is that da Vinci was widely considered to be homosexual.
In truth, we are going to produce a series of inspired poster images over the next few years.
Next year's poster ad may take inspiration from 'American Gothic' by Grant Wood or Edvard Munch's 'The Scream' or even 'The Sound of Music'!
I guess it wouldn't be the Folsom Street Fair without offending some extreme members of the global community, though.
"The Catholic League, Concerned Women for America and the Family Research Council targeted the largest mainstream sponsor of the event, Miller Brewing Company, threatening to boycott their products for the company's support of the event and allowing its logo to appear in the ad.
Miller asked for its logo to be removed from the poster with a statement on its website: "While Miller has supported the Folsom Street Fair for several years, we take exception to the poster the organizing committee developed this year.
We understand some individuals may find the imagery offensive and we have asked the organizers to remove our logo from the poster effective immediately.
"The Catholic League dropped the boycott within a month with no evidence of Miller's sales being affected.
Nancy Pelosi, Speaker of the United States House of Representatives who represents San Francisco and who is also Roman Catholic, fielded a question on this image as part of her Friday morning press conference.
She responded,It's a Constitutional question.
It's a religious question.
It's about as global a question as you could ask...I'm a big believer in the First Amendment.
I do not believe Christianity has been harmed by the Folsom Street Fair. 
[[File:Última Cena - Da Vinci 5.jpg|thumb|400px|right|Depictions of the Last Supper in Christian art have been undertaken by artistic masters for centuries, Leonardo da Vinci's late 1490s mural painting in Milan, Italy, being the best-known example.
]]The Last Supper is the final meal that, according to Christian belief, Jesus shared with his Apostles in Jerusalem before his crucifixion.
The Last Supper is commemorated by Christians especially on Maundy Thursday.
Moreover, the Last Supper provides the scriptural basis for the Eucharist also known as "Holy Communion" or "The Lord's Supper".
The First Epistle to the Corinthians is the earliest known mention of the Last Supper.
The four canonical Gospels all state that the Last Supper took place towards the end of the week, after Jesus' triumphal entry into Jerusalem and that Jesus and his Apostles shared a meal shortly before Jesus was crucified at the end of that week.
During the meal Jesus predicts his betrayal by one of the Apostles present, and foretells that before the next morning, Peter will deny knowing him.
The three Synoptic Gospels and the First Epistle to the Corinthians include the account of the institution of the Eucharist in which Jesus takes bread, breaks it and gives it to the Apostles, saying: "This is my body which is given for you".
The Gospel of John does not include this episode, but tells of Jesus washing the feet of the Apostles, giving the new commandment "to love one another as I have loved you", and has a detailed farewell discourse by Jesus, calling the Apostles who follow his teachings "friends and not servants", as he prepares them for his departure.
Scholars have looked to the Last Supper as the source of early Christian Eucharist traditions.
Others see the account of the Last Supper as derived from 1st-century eucharistic practice as described by Paul in the mid-50s.
