A Moment in History

Jean-Louis Petit

Jean Louis Petit
(1674 – 1750)

French surgeon and anatomist, Jean Louis Petit was born in Paris in on March 13, 1674.  His family rented an apartment at his house to Alexis Littre (1658 – 1726), a French anatomist. Petit became an apprentice of Littre at seven years of age, helping him in the dissections for his lectures and at an early age became the assistant in charge of the anatomic amphitheater.

Because of Petit’s dedication to anatomy and medicine, in 1690 at the age of sixteen, became a disciple of a famous Paris surgeon, Castel.

In 1692, Petit entered the French army and performed surgery in two military campaigns. By 1693 he started delivering lectures and was accepted as a great surgeon, being invited to the most difficult operations.  In 1700 he was appointed Chief Surgeon of the Military School in Paris and in the same year he received the degree of Master of Surgery from the Faculty of Paris.

In 1715 he was made a member of the Royal Academy of Sciences and an honorary member of the Royal Society of London. He was appointed by the King as the first Director General of the Royal Academy of Surgery when it was founded in 1731.

Petit’s written works are of historical importance.  “Traite des Maladies des Os” ( A Treatise on Bone Diseases);  “Traite des Maladies Chirurgicales et des Operation” (A Treatise on Surgical Diseases and their Operations” This last book was published posthumously in 1774. He also published a monograph on hemorrhage, another on lachrymal fistula, and others.

He was one of the first to perform choIecystotomy and mastoidotomy. His original tourniquet design for amputations saved many in the battlefield and the design of the same surgical instrument today has not changed much since its invention by him.

His name is remembered in the lumbar triangle, also called the "triangle of Petit", and the abdominal hernia that can ensue through that area of weakness, the lumbar hernia or "Petit's hernia".

Powerful indications that Vesalius died from scurvy (1)


Text from the presentation at the 2014 Vesalius Continuum Meeting in Zakyhnthos, Greece by Pavlos Plessas.

This article appeared originally on the blog of Fr. Panagiotis Capodistrias, a Zakynthian priest and poet, and a former schoolmate of Pavlos Plessas on September, 2014. Published here with permission from the author


The circumstances of Andreas Vesalius’ death in Zakynthos in 1564 may have been described in one of two differing accounts, originally written by three different men between the years 1565 and 1573, in five different texts. No additional information from people who may have been in possession of some facts is known to have survived.

In two of those texts the writer Petrus Bizarus claims that a travelling goldsmith found the great anatomist abandoned in a miserable hut on a deserted beach, dying from an unspecified illness (1). The unnamed goldsmith, in spite of strong opposition from the locals, buried him with his own hands in a plot of land he purchased for that purpose.

The veracity of Bizarus’ account appears doubtful due to its pervasive vagueness and the improbability of such treatment of an important nobleman by both, the Venetian authorities of Zakynthos and his own companions. More importantly it is incompatible with the testimonies of Christoph Fürer von Haimendorf (2)  and Giovanni Zuallardo (3) , who saw Vesalius’ tomb at the Franciscan monastery of Santa Maria delle Grazie, in 1565 and 1586 respectively. Their testimonies are also supported by that of Filippo Pigafetta (4). From their descriptions it is obvious that Vesalius was buried with some decorum and his grave was not dug simply to prevent the desecration of the body by wild animals.

The rival account is given in two letters of Johannes Metellus (5) , written in 1565, and another by Reinerus Solenander  a year later. Two more of Vesalius’ contemporaries, Carolus Clusius and Henricus Pantaleon provided shortened versions of this account that do not offer additional information and, hence, will not be discussed further. According to Metellus and Solenander Vesalius’ tomb was paid for by a fellow passenger, a Georgius Boucherus of Nuremberg, returning from Egypt. This account is not only compatible with the testimonies of those who saw Vesalius’ tomb but its credibility is enhanced by Metellus’ mention of a gravestone, put up by Boucherus, and Solenander’s statement that Vesalius was buried “next to a chapel or shrine close to the port of Zakynthos”. Santa Maria delle Grazie was the only Western church near the port at the time (7).

In a rather unexpected way this account’s credibility is further strengthened by the astonishing events it describes. For if someone is to present a fabricated account it is natural to try and make it as believable as possible. Even if the aim is to impress or to shock, the disturbing inventions have to have plausible and uncomplicated explanations. Contrary to this we are told of a ship that was unable to reach land for forty days, of severe food and water shortages, the consequent outbreak of an illness that caused many deaths but strangely affected only the pilgrims, Vesalius becoming depressed and anxious – which in the belief of Metellus contributed to his illness – his pleading to the crew to not bury him at sea, and finally his death as soon as they reached land – a very sudden collapse by the city gate according to Metellus. It will be shown that this sequence of extraordinary events has a reasonable, quite likely even, and singular explanation.

Pigafetta, 1608/1612, background information to Map 217. Pigafetta, commenting almost two decades after his visit to Zakynthos in July 1586, mistakenly named the burial place of Vesalius as the monastery of St Francis. However, he leaves no doubt with regards to which monastery he actually meant by corroborating Zuallardo’s story of the inscription’s looting by the Turks in 1571. There was indeed a St Francis monastery in Zakynthos. It was, however, inside the castle and, hence, it was never looted by the Turks. Santa Maria delle Grazie on the other hand was in the area that is known to have been looted.
