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".

According to Theo Dirix, Belgian Consul to Greece and Vesalius enthusiast, there are other reminders on the island such as a painting in one of the local schools.

On September 3rd, 2014, as part of the Vesalius Continuum meeting on Zakynthos Island, a new bronze statue was unveiled to celebrate the life and works of Andrea Vesalius and remember his death on Zakynthos. This statue is a representation of Vesalius’ style of depicting anatomy in his book “De Humani Corporis Fabrica Libri Septem” and is a “muscle man” mixed with the motif of the famous plate 20 of Book 1 that shows a skeleton musing over a skull. The statue also presents the Vesalius family coat of arms. The statue is the work of Richard Neave and Pascalle Pollier.

Pascale Pollier, a biomedical artist specializes in face reconstructions and made a new bust of Vesalius based on the only known portrait of the great anatomist found on the pages of his immortal book “The Humani Corporis Fabrica Libri Septem”.

The statue was unveiled in front of an international crowd of anatomists, medical historians, biomedical artists, and film makers. Following the ceremony a display of artistic works related to Vesalius was opened in the Zakynthos municipality.

These are today the signs of the presence of Vesalius on Zakynthos. We know today that his body is interred in the cemetery of the church of Santa Maria della Grazie in Zakynthos. Sadly this church was destroyed twice in earthquakes and in 1953 was completely demolished along with 85% of the city. It was not rebuilt and now lies under the new, rebuilt city. One of the research papers presented at the 2014 Vesalius Continuum meeting has rediscovered the location of the church with great accuracy. The account of this paper and how I was able to find this geolocation will be presented in another article.

In 2014 the Vesalius Continuum Meeting with the Zakynthos government helped unveil a bronze statue to honor Andreas Vesalius. The statue reminds us of the "philosopher" of Jan Stephan Van Calcar, but in this case it is a muscle man contemplating a skull. At the base of the statue is the Vesalian coat of arms with the three weasels
