The world of art and literature is full of dazzling masterpieces whose authenticity has sparked fierce debates among scholars, collectors, and the curious public.
Why These Masterpieces Whose Provenance Is Contested?
10 Frankenstein; Or, The Modern Prometheus Mary Shelley
Nearly two centuries after its debut, Mary Shelley’s Frankenstein; Or, The Modern Prometheus still haunts readers. The novel cemented her reputation as a pioneering female novelist before the twentieth century. Yet a fringe theory, championed by John Lauritsen in his book The Man Who Wrote Frankenstein, claims the work was actually penned by her husband, poet Percy Bysshe Shelley.
Lauritsen’s argument sounds persuasive at first glance. He has no formal training in literary history and even disputes the scientific link between HIV and AIDS, but he insists that a teenager with limited schooling could not have produced the novel’s sophisticated prose. He also points to recurring themes of male homoeroticism, which he argues align more closely with Percy’s psychology than Mary’s.
According to Lauritsen, feminist scholars have deliberately buried the truth, suppressing the idea that Percy authored the novel. Critics quickly labeled his stance as misogynistic, yet the controversy took an unexpected turn when feminist author Germaine Greer reviewed Lauritsen’s work. Greer argued that Shelley truly wrote Frankenstein, but she dismissed the novel’s literary merit, calling it poorly written.
9 The Bust Of Nefertiti
“Suddenly we had in our hands the most alive Egyptian artwork. You cannot describe it with words. You must see it.” That was archaeologist Ludwig Borchardt’s reaction after his team uncovered the famed bust of Nefertiti, thought to portray the Sun King Akhenaten’s wife.
The bust’s vivid colors and anatomical precision make it feel almost miraculous that a three‑millennium‑old piece could survive intact. Swiss art historian Henri Stierlin, however, offers a wildly different story. He alleges that in 1912 Borchardt commissioned an artist to create a decorative piece to showcase an ancient necklace, then painted the bust using pigments from his archaeological archives. This explains how forensic tests have struggled to disprove its age.
When the Prussian prince Johann Georg saw the work, he mistook it for an authentic antiquity and fell in love with it. Borchardt, apparently too nervous to correct the prince, let the deception continue. Today the bust resides in Berlin’s museum, celebrated as a 3,000‑year‑old treasure—though Stierlin insists it’s really a century‑old fake.
Even skeptics like scientist Stefan Simon concede that “you can prove a fake, but you can’t prove originals,” keeping the debate alive.
8 Flowers Paolo Porpora
If you wander into Taipei, Taiwan, you might encounter a still‑life titled Flowers, purportedly by 17th‑century painter Paolo Porpora. An Italian auction house later revealed that the same canvas had been catalogued as the work of a lesser‑known artist, Mario Nuzzi.
Misattributions happen, but this case exploded when surveillance footage captured a 12‑year‑old boy punching a hole through the painting after losing his footing in August 2015. The viral video prompted the auction house to announce the error publicly.
The damaged piece was originally touted as a $1.5 million masterpiece, yet the Nuzzi version is valued at roughly $30,000. The organizers of the “Face of Leonardo, Images of a Genius” exhibition continue to assert the work is an authentic Porpora, despite lacking proof. Adding to the intrigue, the entire Taipei showcase operates out of a rented venue without climate control or proper security, and even the Leonardo self‑portrait on display is of dubious authenticity.
7 La Bella Principessa Leonardo Da Vinci
The portrait known as La Bella Principessa (The Beautiful Princess) vanished into obscurity until a 1998 auction, where it was initially thought to be a 19th‑century German work. After rigorous testing led by Oxford Renaissance scholar Martin Kemp, the piece was declared a genuine Leonardo drawing.
Kemp’s team examined everything from pigment composition to brushstroke direction, noting that a single right‑handed stroke would normally disqualify a work by the left‑handed Leonardo. Yet the comprehensive analysis convinced many authorities to accept the attribution.
Detractors persist. Critics argue the drawing lacks Leonardo’s characteristic spirit and point out the use of vellum—a material Leonardo never employed. In 2015, convicted forger Shaun Greenhalgh claimed the piece was his own creation, saying he modeled it after a supermarket employee. Owner Peter Silverman has challenged Greenhalgh to recreate the drawing before a panel of experts, offering a £10,000 prize for success and insisting that failure would send the forger back to prison.
6 Ariel And Other Poems Sylvia Plath
In 1963, 31‑year‑old poet Sylvia Plath was grappling with a strained marriage to Ted Hughes while caring for their two young children in London. Tragically, she died by suicide on February 11, 1963. Posthumously, a collection of her poems titled Ariel and Other Poems was published in 1965 and swiftly hailed as a twentieth‑century masterpiece.
Controversy arises because Hughes, who served as Plath’s literary executor, rearranged the poem order and omitted pieces he deemed “personally aggressive”—essentially, poems aimed at him. In 2004, Plath’s daughter collaborated on a new edition, Ariel: The Restored Edition, which restores the original sequence and includes poems omitted by Hughes.
Reviewers noted a tonal shift: Hughes’s edition emphasizes despair, whereas the restored version ends on a hopeful note. The original concludes with the bleak “Edge,” while the restored edition finishes with the meditative “Wintering,” which ends with optimistic lines about Christmas roses and buzzing bees tasting spring.
5 Teri Horton’s Jackson Pollock
Teri Horton, a 73‑year‑old former truck driver, bought a painting for five dollars at a thrift shop, intending it as a gift. When it proved too large for the recipient’s trailer, she sold it at a yard sale. An art teacher recognized the work’s striking similarity to Jackson Pollock’s signature style.
Forensic analysis revealed a fingerprint matching those found on authenticated Pollock canvases. Additionally, Nicolas Carone—an acclaimed painter and friend of Pollock—testified to the painting’s authenticity. Skeptics, however, question the fingerprint evidence and argue the piece is too inferior to be a genuine Pollock, whose technique is notoriously difficult to replicate.
Regardless of its disputed status, Horton received a $9 million offer from a Saudi buyer, which she declined, insisting on a minimum of $55 million. The saga is dramatized in the documentary Who the #$&% is Jackson Pollock?
4 To Kill A Mockingbird Harper Lee
Truman Capote and Harper Lee grew up as childhood friends in Monroeville, Alabama. Their divergent personalities—Capote the flamboyant party animal, Lee the reclusive homebody—made their eventual estrangement almost inevitable. Before their split, they exchanged critiques and encouragement on each other’s work.
Rumors began swirling when Cambridge editor Pearle Belle claimed Capote confessed to her that he wrote much, if not all, of Lee’s landmark novel To Kill a Mockingbird. Capote’s father, Archulus Persons, allegedly echoed the claim, saying Lee only supplied the outline while Capote “made the novel sing.”
The controversy seemed to settle when a 2013 letter from Capote to Lee surfaced, congratulating her without any hint of collaboration. Historian Wayne Flynt reinforced Lee’s authorship, noting Capote’s notorious ego and self‑promotion: “To assume, as jealous as Capote was of Harper Lee’s success, that he would not have claimed credit for Mockingbird if he had written it, is simply too much…to believe.”
3 The Madonna Of The Pinks Raphael
For centuries, art apprentices honed their craft by copying the masters, and those copies were often prized. It was therefore a shock when a tiny oil painting, long believed to be a genuine Raphael work titled The Madonna of the Pinks, turned out to be a copy.
In 1860, Raphael scholar Johann David Passavant denounced the piece as a replica. Decades later, in 1991, curator Nicholas Penny re‑examined the painting, noting a minute anomaly in the background. Using modern forensic techniques, he uncovered an underdrawing characteristic of Raphael’s hand, prompting a re‑attribution to the master.
Nevertheless, acerbic critic Brian Sewell remained unconvinced, arguing the quality and chronology (the painting was said to be an early work from 1506‑1507) made Raphael’s authorship unlikely. Sewell famously observed, “There are a lot of people who want to be fooled…If you discover a genuine Rembrandt…you become associated with it. It makes you important, because it is important.”
2 Portrait Andy Warhol
The portrait titled “Bruno B” depicts Andy Warhol himself, produced using one of his own silk‑screen plates and dedicated to his friend, dealer Bruno Bischofberger. Warhol loved the work so much that he chose it for the cover of the first major monograph of his oeuvre, published in 1970.
Despite these credentials, the Andy Warhol Authentication Board denied the piece’s authenticity, arguing that Warhol was not physically present during its creation. The painting had been silk‑screened by an independent firm that had permission to use Warhol’s plates.
Warhol’s own practice, however, involved delegating the actual execution to assistants at his studio—famously called “The Factory.” He often only conceptualized works and signed them. Curator Sam Green noted that Warhol admired “Bruno B” precisely because it exemplified his technique of having works produced without his direct hand.
The board’s denial therefore appears to be an overreach by a foundation whose members were never appointed by Warhol himself.
1 The Polish Rider Rembrandt
In 1639, Dutch master Rembrandt bought a sprawling house in Amsterdam—a purchase that eventually led to his 1656 bankruptcy. To finance the property, he took on a large cohort of students, whose talents later complicated attribution efforts for years to come.
The Rembrandt Research Project (RRP), launched in 1968, set out to authenticate every Rembrandt painting. Its findings caused a dramatic swing: over 700 works were considered authentic in the 1920s, but by the 1980s that number fell to just under 300. The project’s conclusions have been revised multiple times, reflecting the difficulty of pinning down authorship.
The painting at the center of today’s debate is The Polish Rider, housed in New York’s Frick Collection. Long hailed as a Rembrandt masterpiece, a member of the RRP cast doubt on its authenticity. Other scholars countered, and the consensus now holds that the work is indeed by Rembrandt, albeit with substantial contributions from his students.
Robert Hughes summed up the era’s murky standards: “If one of Rembrandt’s students did a painting he liked, he was quite capable of signing it with his own name, keeping it and selling it as an autographed work by ‘Rembrandt.’ Criteria of originality and authorship were much more relaxed in the 17th century than they are now.”
