Leonardo da Vinci: Famous Works, Death Cause & Right Hand Palsy

Few figures from history feel as modern as Leonardo da Vinci. We know him for the Mona Lisa’s elusive smile and flying machines sketched centuries before the Wright brothers, yet his final years hold a puzzle that still divides medical experts today. This article separates the documented facts from the retrospective diagnoses, examining what we actually know about his death, his right hand palsy, and how the man who embodied the Renaissance spent his last days. You’ll find a clear picture of the evidence — and where the gaps remain.

Born: April 15, 1452, Anchiano, Italy ·
Died: May 2, 1519, Amboise, France ·
Known for: Painting, drawing, engineering, anatomy, invention ·
Famous works: Mona Lisa, The Last Supper, Vitruvian Man ·
Cause of death hypothesis: Right hand palsy, possible stroke

Six key facts, one pattern: the gap between what is confidently known and what remains medically speculative is wider than most biographies admit.

What was Leonardo da Vinci famous for?

His masterpieces: Mona Lisa and The Last Supper

Leonardo da Vinci remains the most recognizable name of the Italian Renaissance, largely because of two paintings. The Mona Lisa, begun around 1503, draws millions yearly to the Louvre Museum (Paris), its subject’s expression still debated. The Last Supper, painted between 1495 and 1498 on a refectory wall in Milan’s Santa Maria delle Grazie, survives despite experimental technique that began deteriorating almost immediately (Encyclopaedia Britannica).

Roles as a scientist, inventor, and engineer

Beyond painting, Leonardo filled thousands of pages with anatomical drawings, mechanical designs, and studies of water flow. His notebooks — over 7,200 pages survive today according to the British Library — reveal a mind constantly testing ideas: flying machines, war engines, and detailed human dissections (Encyclopaedia Britannica).

The implication: “Renaissance man” isn’t a compliment — it’s a job description he wrote himself.

What are 5 facts about da Vinci?

Fact 1: He was a prolific note-taker

Leonardo kept thousands of pages of notes and sketches, covering everything from human anatomy to hydraulic engineering (British Library).

Fact 2: He studied human anatomy in detail

He performed human dissections to study anatomy, producing some of the earliest accurate drawings of the human body.

Fact 3: He designed flying machines

He sketched designs for a flying machine and a helicopter-like device, centuries before powered flight.

Fact 4: The Mona Lisa has no eyebrows

The Mona Lisa famously appears to have no eyebrows, a detail that has sparked centuries of speculation (Louvre Museum).

Fact 5: He was left-handed

He was left-handed and wrote in mirror script, a habit that has fascinated historians (National Gallery, London).

The pattern: these facts share a theme — Leonardo was never content with one discipline.

What caused da Vinci’s death?

Historical accounts of his final days

Leonardo da Vinci died on May 2, 1519, at Clos Lucé in France (Encyclopaedia Britannica). Contemporary accounts mention a long illness, but the immediate cause of death is not reliably documented in surviving records (Encyclopaedia Britannica).

Medical hypothesis: right hand palsy and stroke

A leading hypothesis comes from a 2019 study in the Journal of the Royal Society of Medicine (PMC) by Dr. Carlos Lázaro and Dr. Diego Lázaro. They argue that Leonardo’s right-hand impairment is better explained by ulnar palsy than by stroke, based on analysis of a 16th-century drawing of his hand. However, the same article states that an acute cardiovascular event could still have been the cause of death even if the hand impairment had a different cause (Journal of the Royal Society of Medicine (PMC)).

What this means: after 500 years, medical experts can’t agree on how Leonardo lost the ability to paint — and they may never reach consensus.

What disability did Leonardo da Vinci have?

The right hand palsy diagnosis

Leonardo da Vinci suffered from right hand palsy in his later years (Journal of the Royal Society of Medicine (PMC)). The key historical source is the 1517 visit by Antonio de Beatis, who noted that Leonardo’s right hand was impaired but that he was left-handed and could still draw (National Gallery, London).

How it affected his later work

Despite the palsy, Leonardo continued to teach and draw (National Geographic Historia). The National Gallery states that a stroke may have left him paralyzed down the right side of his body (National Gallery, London), but this is disputed by the 2019 PMC study, which notes that the depicted hand posture does not resemble the clenched hand typical of post-stroke spasticity (Journal of the Royal Society of Medicine (PMC)).

The trade-off: the medical debate matters because it changes how we interpret his final years — was he a stroke victim or a man with a nerve injury who still produced?

Did da Vinci have a child?

No confirmed biological children

Historians have found no credible evidence that Leonardo da Vinci had any biological children (Encyclopaedia Britannica).

His close relationship with Francesco Melzi

He had a close bond with his pupil Francesco Melzi, who became his heir (Encyclopaedia Britannica). Speculation about a child from his relationship with Cecilia Gallerani is unproven.

The implication: his legacy was passed through his art and his pupils, not through blood.

What did da Vinci say before he died?

The attributed last words

Leonardo da Vinci’s reported last words: “I have offended God and mankind because my work did not reach the quality it should have.” The quote appears in Giorgio Vasari’s Lives of the Most Excellent Painters, Sculptors, and Architects (1550).

Historical reliability of the quote

Historians debate the accuracy of Vasari’s account, as it was written decades after Leonardo’s death (Encyclopaedia Britannica). King Francis I of France was reportedly present at Leonardo’s deathbed and described him as a great philosopher, but no record of the last words exists from contemporary witnesses.

The catch: we may never know what Leonardo actually said, but the quote tells us more about how he wanted to be remembered than any medical report could.

Did da Vinci have ADHD?

Modern retrospective hypothesis

Some modern researchers have suggested Leonardo da Vinci may have had ADHD based on his constant shifting between projects (Brain journal (PubMed Central)). A 2019 study in the journal Brain proposed ADHD as an explanation for his procrastination and restlessness.

Evidence from his work habits

This is a retrospective diagnosis; no contemporary records state he had the condition (Encyclopaedia Britannica). The 2019 study notes that Leonardo’s pattern of leaving works unfinished and hopping between disciplines is consistent with ADHD traits.

The trade-off: diagnostic labels 500 years after death are inherently speculative, but they offer a humanizing lens — one that explains his endless curiosity without diminishing his achievements.

Timeline

• 1452: Born in Anchiano, near Vinci, Italy (Encyclopaedia Britannica).
• 1466: Apprenticed to artist Andrea del Verrocchio in Florence (Encyclopaedia Britannica).
• 1482-1499: Works in Milan for Ludovico Sforza; paints The Last Supper (Encyclopaedia Britannica).
• 1503: Begins painting the Mona Lisa (Encyclopaedia Britannica).
• 1516: Moves to France under patronage of King Francis I (Encyclopaedia Britannica).
• 1517: Suffers right hand palsy; can no longer paint (National Gallery, London).
• 1519: Dies at Clos Lucé, Amboise, France (Encyclopaedia Britannica).

The timeline confirms that Leonardo’s final years were marked by a sharp decline in his ability to paint.

For readers looking to understand Leonardo’s final years, the choice is clear: accept the uncertainty of retrospective medical diagnoses, or settle for the incomplete but honest story — a genius who lost the ability to paint but never stopped creating.
