Portrait of the mathematician as a young man: Revisiting Trinity's Tayler picture

This paper challenges the identification of a 17th-century Trinity College portrait as Isaac Barrow by highlighting historical and visual inconsistencies, proposing instead that the sitter is likely Francis Willughby or Isaac Newton, with the latter identification offering new insights into Newton's rapid academic ascent.

The Gist

Imagine you've found an old, dusty painting in the attic of a famous university. It shows a young man with blond hair and blue eyes, wearing a scholar's robe, pointing proudly at a specific page in a math book. For decades, the university has hung a label on it saying, "This is Isaac Barrow," a famous mathematician and teacher.

But a physicist named Alejandro Jenkins is looking at that painting and thinking, "Wait a minute. Something doesn't add up."

This paper is essentially a detective story about a 17th-century portrait. Jenkins is trying to solve the mystery of who is actually sitting in that chair. Here is the breakdown of the case, explained simply.

The Crime Scene: The "Tayler Picture"

The painting in question is called the "Tayler picture." It hangs in Trinity College, Cambridge.

• The Clue: The young man is pointing at a math book. Specifically, he's pointing at a page in a 1655 edition of Euclid's Elements (the classic geometry textbook), translated by Isaac Barrow.
• The Official Story: The college believes this is a portrait of Isaac Barrow (the teacher) when he was young.
• The Problem: Jenkins argues this is like finding a photo of a teacher holding a textbook they wrote, but the teacher looks nothing like the photos we have of them, and the timeline doesn't make sense.

The Suspects

Jenkins looks at the evidence and narrows it down to three main suspects:

1. The Original Suspect: Isaac Barrow (The Teacher)

• Why it doesn't fit:
  • The Look: Barrow was described as short, lean, with grey eyes and curly, light-brown hair. The guy in the painting has blue eyes, straight blond hair, and a high forehead. They look like different people.
  • The Timing: The book in the painting was published in 1655. But Barrow had already left England to travel Europe for four years by the time that book came off the press. It's highly unlikely he would have posed for a portrait holding a book that was published while he was on vacation.
  • The Attitude: Barrow actually hated that first edition of his book. He called it a "meane worke" (a mediocre job) and said it needed fixing. Why would he pose proudly with a book he was embarrassed by?

2. The "Rich Kid" Suspect: Francis Willughby

• The Theory: The book in the painting was dedicated to three wealthy students, one of whom was Francis Willughby. Willughby had blond hair and blue eyes, just like the guy in the painting.
• Why it's possible: Maybe the painting is of Willughby, showing off the book dedicated to him.
• Why it's unlikely: Willughby was very wealthy and famous. He would have hired a top-tier, fancy artist. The artist of this painting seems to be a local, less famous painter. Also, Willughby wasn't really a math genius; he was more of a nature lover (he studied birds and fish).

3. The "Hidden Genius" Suspect: Isaac Newton

• The Theory: This is Jenkins' favorite idea. He thinks the painting is actually a young Isaac Newton.
• The Evidence:
  • The Look: Young Newton had blond hair, blue eyes, and a high forehead. This matches the painting perfectly.
  • The Book: Newton famously struggled with geometry at first. His teacher, Barrow, helped him get back on track. Newton actually owned a copy of that exact 1655 book and filled it with notes, corrections, and drawings. The painting shows the sitter pointing to a specific math problem about circles—a topic Newton studied deeply.
  • The "Dog-Ear" Clue: In the painting, the corner of the book page is folded down. Newton was known for folding the corners of his books (dog-earing) to mark important spots.
  • The Motivation: Newton started at the university as a "subsizar" (a poor student who did chores for other students to pay for his tuition). He needed a powerful patron to help him rise. By painting himself pointing at Barrow's book, Newton might have been sending a message: "I am Barrow's true disciple. I study his work deeply. Please help me succeed."

The "Sherpa" of the Story: Humphrey Babington

The paper also introduces a new character: Humphrey Babington.

• Think of Babington as Newton's "Sherpa" or mentor. He was a wealthy, well-connected clergyman who knew Newton's family.
• Jenkins suggests Babington might have paid for this painting. Why? To help his young protégé, Newton, look like a serious scholar and gain the attention of the university elite. It was a strategic move to boost Newton's career before he became famous.

The Big Picture: Why Does This Matter?

If Jenkins is right, this isn't just about swapping a name on a label. It changes how we see Newton's early life.

• The "Rags to Riches" Story: It shows Newton wasn't just a lonely genius who woke up one day and invented calculus. He was a young man actively trying to build a network, find a mentor, and climb the academic ladder.
• The Missing Link: We have very few pictures of Newton when he was young. If this is him, it's a rare glimpse of the man before he became the most famous scientist in history.

The Verdict

Jenkins concludes that while we can't be 100% sure without more scientific testing (like cleaning the paint to see the layers underneath), the evidence points strongly away from Barrow and toward Newton.

It's like finding a photo of a young, unknown actor holding a script from a famous director. For years, people thought it was the director. But the actor looks exactly like the young version of the star, and the script is one the actor famously studied and annotated. It turns out the photo isn't of the teacher; it's the student, trying to prove he's ready for the big stage.

Technical Summary

Technical Summary: "Portrait of the mathematician as a young man: Revisiting Trinity's Tayler picture"

1. Problem Statement
The paper addresses a significant gap in the iconography of Isaac Newton and 17th-century English portraiture. While Newton sat for numerous portraits later in life, there is a lack of authenticated contemporary images of him as a young man. A specific oil painting, known as the "Tayler picture" (currently in the collection of Trinity College, Cambridge), has traditionally been identified as a portrait of Isaac Barrow (Newton's predecessor as Lucasian Professor). The author, Alejandro Jenkins, challenges this identification based on three primary inconsistencies:

• Physical Dissimilarity: The sitter in the Tayler picture (blond, blue-eyed, high forehead) bears little resemblance to authenticated portraits of Barrow (described as lean, grey-eyed, and short-sighted).
• Chronological Improbability: The painting depicts the sitter pointing to a specific proposition in Barrow's 1655 Latin edition of Euclid's Elements. Barrow left England for a four-year continental tour eight months before this edition was printed, making it highly unlikely he would have posed with a book published while he was abroad.
• Historical Context: The painting's provenance links it to the Tayler family, who had connections to Trinity College and James Clerk Maxwell, but the specific identity of the sitter remains unverified beyond family oral tradition.

2. Methodology
Jenkins employs a multidisciplinary approach combining art history, historical biography, and textual analysis:

• Iconographic Analysis: A comparative visual analysis of the Tayler picture against authenticated portraits of Barrow (by Mary Beale and David Loggan) and known portraits of Newton (by Godfrey Kneller and Enoch Seeman).
• Provenance and Historical Reconstruction: Tracing the ownership history of the painting from the Tayler family to Trinity College and analyzing the biographical timelines of potential sitters (Barrow, Newton, Francis Willughby).
• Textual Verification: Examining the specific pages of the book depicted in the painting (Euclid's Elements, Book 12, Proposition 2) and cross-referencing them with Barrow's publication history and Newton's known annotations in his personal copy of the same edition.
• Contextual Interpretation: Analyzing the social and academic dynamics of 17th-century Cambridge, specifically the patronage networks involving Newton, Barrow, and the Rev. Humphrey Babington.

3. Key Contributions

• Rejection of the Barrow Attribution: The paper provides compelling evidence that the Tayler picture is not a portrait of Isaac Barrow, citing physical discrepancies and the chronological impossibility of Barrow posing with the 1655 edition of Euclid.
• Identification of the Book: The author definitively identifies the book in the painting as Barrow's 1655 edition of Euclid's Elements, noting the specific indentation of text and the depiction of Proposition 2 in Book 12 (regarding the area of circles).
• Proposal of Alternative Sitters:
  • Isaac Newton: Jenkins argues the sitter is likely a young Newton. The physical features (blond hair, blue eyes, high forehead) match descriptions of Newton in his youth. The act of pointing to Barrow's Euclid is interpreted as a symbolic gesture of Newton's intellectual debt to Barrow and his successful courtship of Barrow's patronage.
  • Francis Willughby: A secondary candidate, as Willughby was one of the three undergraduates to whom Barrow dedicated the 1655 Euclid. However, Jenkins ranks this less likely due to Willughby's higher social status, which would likely have warranted a more fashionable artist (like Gerard Soest) rather than the provincial style of the Tayler painter.
• Patronage Hypothesis: The paper introduces a novel hypothesis regarding Newton's early career advancement. It suggests the portrait may have been commissioned by Humphrey Babington, a wealthy fellow of Trinity and Newton's early protector. The painting is posited as a strategic tool used by Newton (or Babington on his behalf) to visually establish Newton as Barrow's true intellectual disciple, distinguishing him from Willughby (the book's dedicatee) and securing his rise from a subsizar (poor student) to a Fellow and eventually the Lucasian Professor.

4. Results

• Visual Evidence: The sitter's blue eyes and blond hair align with descriptions of young Newton and contrast sharply with the grey eyes and darker hair of Barrow.
• Historical Evidence: Newton is known to have extensively annotated his own copy of Barrow's 1655 Euclid, correcting errors and adding diagrams. The painting depicts a "dog-eared" page, a habit associated with Newton's study methods.
• Chronological Alignment: The painting likely dates to the period between Newton's election as a Scholar (1664), a Fellow (1667), or his appointment as Lucasian Professor (1669). The depiction of Newton pointing to Barrow's work serves as a visual narrative of his academic ascent under Barrow's mentorship.
• Stylistic Analysis: The painting's style suggests a provincial English artist, consistent with a commission by a patron like Babington rather than a wealthy aristocrat like Willughby.

5. Significance

• Resolution of an Art Historical Mystery: If confirmed, this would provide the first authenticated portrait of Isaac Newton as a young man, filling a critical gap in the visual history of one of science's most important figures.
• Insight into Newton's Early Career: The paper reframes Newton's early success not merely as a result of innate genius but as a product of strategic networking and patronage. It highlights the role of Humphrey Babington and the deliberate cultivation of a relationship with Isaac Barrow.
• Methodological Impact: The study demonstrates how combining art historical analysis with deep historical context (publication dates, biographical timelines, and social hierarchies) can correct long-standing misidentifications in museum collections.
• Future Research: The author calls for physical restoration and expert examination of the painting (e.g., analyzing the gown's color and material) to further verify the identity of the sitter and the artist, potentially rewriting the early narrative of Newton's life at Cambridge.
