A Moment in History

Andreas Vesalius Bruxellensis (1514- 1564)

A Flemish anatomist and surgeon, Andreas Vesalius was born on December 31, 1514 in Brussels, Belgium. He is considered to be the father of the science of Anatomy. Up until his studies and publications human anatomy studies consisted only on the confirmation of the old doctrines of Galen of Pergamon (129AD - 200AD). Anatomy professors would read to the students from Galen's work and a demonstrator would point in a body to the area being described, if a body was used at all. The reasoning was that there was no need to dissect since all that was needed to know was already written in Galen's books. Vesalius, Fallopius, and others started the change by describing what they actually saw in a dissection as opposed to what was supposed to be there. 

Vesalius had a notorious career, both as an anatomist and as a surgeon. His revolutionary book "De Humani Corporis Fabrica: Libri Septem" was published in May 26, 1543. One of the most famous anatomical images is his plate 22 of the book, called sometimes "The Hamlet". You can see this image if you hover over Vesalius' only known portrait which accompanies this article. Sir William Osler said of this book "... it is the greatest book ever printed, from which modern medicine dates" 

After the original 1543 printing, the Fabrica was reprinted in 1555. It was re-reprinted and translated in many languages, although many of these printings were low-quality copies with no respect for copyright or authorship.

The story of the wood blocks with the carved images used for the original printing extends into the 20th century. In 1934 these original wood blocks were used to print 617 copies of the book "Iconaes Anatomica". This book is rare and no more can be printed because, sadly, during a 1943 WWII bombing raid over Munich all the wood blocks were burnt.

One interesting aspect of the book was the landscape panorama in some of his most famous woodcuts which was only "discovered" until 1903.

Vesalius was controversial in life and he still is in death. We know that he died on his way back from a pilgrimage to Jerusalem, but how he died, and exactly where he died is lost in controversy. We do know he was alive when he set foot on the port of Zakynthos in the island of the same name in Greece. He is said to have suddenly collapsed and die at the gates of the city, presumably as a consequence of scurvy. Records show that he was interred in the cemetery of the Church of Santa Maria delle Grazie, but the city and the church were destroyed by an earthquake and Vesalius' grave lost to history. Modern researchers are looking into finding the lost grave and have identified the location of the cemetery. This story has not ended yet.

Personal note: To commemorate Andrea Vesalius' 500th birthday in 2014, there were many scientific meetings throughout the world, one of them was the "Vesalius Continuum" anatomical meeting on the island of Zakynthos, Greece on September 4-8, 2014. This is the island where Vesalius died in 1564. I had the opportunity to attend and there are several articles in this website on the presence of Andreas Vesalius on Zakynthos island. During 2015 I also attended a symposium on "Vesalius and the Invention of the Modern Body" at the St. Louis University. At this symposium I had the honor of meeting of Drs. Garrison and Hast, authors of the "New Fabrica". Dr. Miranda

Paracelsus

This article is part of the series "A Moment in History" where we honor those who have contributed to the growth of medical knowledge in the areas of anatomy, medicine, surgery, and medical research.

Paracelsus
Paracelsus

Paracelsus (1493 – 1541). Swiss physician and alchemist , Phillipus Aureolus Theophrastus Bombastus Von Hohenheim was born in Einsiedeln in 1493 (one year after Columbus discovered America) in what is today is Switzerland. At an early age he became a migrant student, visiting several universities including Tubingen, Vienna, Wirttemberg, Heidelberg,  and Cologne. There is discussion as to whether he received or not a medical degree, although most authors today agree he might had. In 1510 he moved to Ferrara where he attained (apparently) his medical degree in 1516. During his constant travels he started to understand that folk medical treatment based on actual observation was better than what was published and followed blindly by the physicians of the time.

He started to call himself “Paracelsus” which means “alongside Celsus”, seen as one of the greatest physicians in history. Paracelsus continued his travels, visiting Egypt and Jerusalem. It is at this time that he started delving into the world of alchemy, returning to his home circa 1524.

Paracelsus was appointed “Town Physician” of the city of Basle but created controversy when he started lecturing in German (not Latin) and invited the general public as well as his students to his lectures. In his presentations he introduced the concepts of direct observation of the patient and empirical treatment, based his statements on experiments and reasoning opposing the “classics” Galen, and Avicenna.

In 1527, during a demonstration he publicly burned the works of Avicenna to prove his point. This caused a backlash from the university and town authorities who expelled him in 1528. From this point on, Paracelsus’ life is constant wandering. He settles for a time and then travels again. In spite of his disdain for the works of the “medical greats”, he himself writes a large number of works, including medicine, surgery, theology, astronomy, magic, etc.  Many of these works are not published until after his death as he is considered to be contradicting Galen. In 1530 he writes the best description of syphilis and recommended its treatment with mercury.

In 1541 he was appointed to a post on the staff of Duke Ernest of Bavaria, but he died in mysterious circumstances on September 24 of that year at the White Horse Inn in Salzburg.

Paracelsus is a controversial image, bound in legend. For many, Paracelsus was bombastic, quarrelsome, opinionated and a drunkard. For others he is a figure of his time, clashing with the classics and giving us a new way to look at the world and at diseases. He taught that wounds must be allowed to drain and not, as was common, packed with unhealthy materials.  According to him, the human body primarily consists of salt, sulphur, and mercury, and it is the separation of these elements that causes illness. He introduced mineral baths and made opium, mercury, lead and other minerals part of his treatment, foreshadowing modern pharmacology with the use of chemical remedies, mercury for syphilis, laudanum and antimony. Paracelsus stated in 1538 that “Everything is a poison, the dose alone which makes a thing not a poison”.

I just discovered an interesting chain of events. For a time Paracelsus had a medical student that later decided not to continue his medical studies and instead dedicated himself to the new art of printing. His name was Johannes Oporinus and he was the printer that Andreas Vesalius selected to print his masterpiece, the "Fabrica".
