When Did Leonardo da Vinci Die? The Clavicle Injury, Stroke, and Six-Decade Paper Trail That Pinned the Date

Leonardo da Vinci died on May 2, 1519, at the Château du Clos Lucé in Amboise, France, at about age 67. He had spent his final three years there as a guest of King Francis I. The death date itself is secure. What killed him, and what the eyewitness accounts actually say, is far murkier than most short biographies admit.

What the death record and witnesses establish

The date rests on two independent strands. First, the burial record: Leonardo was interred at the church of Saint-Florentin in Amboise, and his death was entered into the parish register on May 2, 1519. That register survives only in later copies and antiquarian transcriptions, which matters for forensic rigor.

Second, the witness account. Giorgio Vasari, writing in the 1550 edition of his Lives of the Artists, states that Leonardo died in the arms of Francis I at Amboise. That dramatic image is the one most people have seen. But Vasari wrote roughly 31 years after the event and never visited France.

A second account comes from the Florentine notary Francesco Melzi, Leonardo's close pupil and heir, who was present at Clos Lucé in 1519. Melzi's letter to Leonardo's half-brothers describing the death is considered more trustworthy on logistics than Vasari's scene-setting.

The result: the date, place, age, and burial are well attested. The deathbed romance is not.

How the injury, age, and stroke combine

Leonardo had a documented right-hand impairment beginning around 1517, roughly two years before his death. The evidence is indirect but consistent. He largely stopped drawing with his right hand. He relied on assistants, especially Melzi, to execute late mechanical drawings.

The leading interpretation, advanced in a 2019 review in the Journal of the Royal Society of Medicine, is a chronic right hemiparesis affecting his ulnar nerve or the cortical territory serving his hand. The likely proximate cause is a stroke. The likely background cause is a fall that produced a traumatic lesion or nerve injury.

What makes this a mechanism story rather than a guess is the sequence. A peripheral nerve injury from a fall can produce hand weakness without cognitive decline. A stroke can produce both. Leonardo's late notebooks show intact reasoning but faltering manual execution, which favors a peripheral or partial cortical lesion over a massive stroke.

Age matters here. Leonardo was born April 15, 1452. At death he was 67 years and 17 days old. In 1519, a 67-year-old man with partial paralysis and probable cardiovascular disease faced a very narrow treatment landscape. There were no antibiotics, no anticoagulants, and no imaging. Survival after a major stroke was measured in days to weeks.

That context explains why the death date is not a mystery. A person with a two-year history of progressive hand impairment, alive and working in 1517, dying in 1519 at age 67, is a clinically plausible profile. The record does not strain credibility.

Timeline: what happened, and when we know it

Notice the asymmetry in the table. The two anchor events, arrival in France and death in 1519, are the better documented. The middle years, where the medical story lives, rely on inference from what Leonardo stopped doing.

The counterintuitive detail: a 2019 Royal Society of Medicine paper concluded that Leonardo's right-hand impairment was most likely a chronic deficit from a stroke, but a competing analysis of his handwriting and mirrored script patterns argues the injury was an isolated ulnar nerve lesion. Both camps agree on the outcome, a functioning mind with a failing hand. They disagree on which lesion caused it.

What "in the arms of the king" actually means

The most repeated claim about Leonardo's death is the one with the weakest evidentiary base. Vasari's account of Francis I cradling the dying artist exists in no contemporaneous source. The king was not at Clos Lucé. He was at Saint-Germain-en-Laye, about 130 miles away, on the day Leonardo died, according to court records.

Vasari may have been smoothing a narrative. He was writing for patrons who wanted a dignified, royal-adjacent death for a celebrated Italian artist in French service. The story served that purpose well.

The red flags for anyone reading popular accounts:

Treating Vasari as an eyewitness when he wrote decades later and never crossed the Alps. Confusing the date of death with the date of burial records, which were often entered later. Repeating the "stroke while dictating" or "died of a fever" stories, which have no primary source. Accepting "he died at 67" without noting that the exact birth date is known, so the age at death is precise to the day. Assuming the cause of death is documented, when no physician's account survives.

Plain version: the date is solid, the death scene is a story, and the cause of death is a modern inference, not a historical fact.

Where the different claims come from

The table is the useful takeaway. Every row except Vasari's is compatible with the same date. The date survives all the disputes about mechanism. That is the practical lesson.

What the 1519 death date actually settles

The death date matters less for biography than for provenance. It fixes the terminal boundary of a roughly 7,000-page manuscript corpus, including the Codex Arundel, the Codex Atlanticus, and the Windsor anatomical sheets. Scholars dating individual folios use May 2, 1519, as the hard cutoff.

It also settles inheritance. Melzi inherited Leonardo's manuscripts and transported them to Italy, where they were later dispersed. Without a firm death date, tracing that transfer chain through French, Italian, and Spanish collections becomes materially harder.

The date also bounds a puzzle that keeps resurfacing. Leonardo painted very little after about 1515. The Mona Lisa, begun around 1503, was likely still in his possession in France. A 1519 death date means the painting was either unfinished or being reworked at the end.

There is a specific edge case worth flagging. Some French records list May 2, others record the death as May 3 based on when the parish entry was made. The modern consensus favors May 2 for the death and separates the burial timeline. If you see a source citing May 3, check whether it is reporting death or interment.

The practical threshold for trust is simple: if a source names Amboise and May 2, 1519, it is correct. If it adds a deathbed scene with the king, it is repeating Vasari. If it names a specific cause of death without a qualifier, it is overreaching.

How to verify the date yourself

If you need to check the death date in a primary or near-primary source, work in this order:

Start with Melzi's letter to Leonardo's half-brothers, the closest thing to a contemporary eyewitness account. Cross-check the Saint-Florentin parish register transcriptions held in Amboise municipal archives. Use the Royal Society of Medicine 2019 paper for the medical interpretation, not for the date. Treat Vasari's Lives as a secondary source, useful for reception, weak for biography. Reject any date other than May 2, 1519, unless the source explains why a variant exists.

For general readers, the useful threshold is one sentence. Leonardo da Vinci died on May 2, 1519, at age 67, at Amboise. Everything beyond that is interpretive.

Limitations and the honest bound

The mechanism section of this article is inference, not record. No physician attended Leonardo in a documented way. No autopsy exists. The neurological interpretation depends on dating his late manuscripts accurately, and that dating is not perfectly settled.

Vasari's account survives in editions printed decades after the event. Parish registers from 1519 France were frequently copied and recopied. Melzi's letter is the strongest single source, and even it is not an autopsy.

What can be concluded with confidence: the date, place, and age. What cannot: the specific lesion, the exact cause of death, and whether any witness was present at the final hour. Anything claiming more precision than that is editorializing.
