NOTE: In 2014 Pavlos Plessas presented the compelling theory that Andreas Vesalius died in 1564 from scurvy on the island of Zakynthos. With his permission his original article entitled "Powerful indications that Vesalius died from scurvy" was published in this blog in 2016. His theory was later challenged by Theo Dirix and Dr. Rudi Coninx in this same blog with the article "Did Andreas Vesalius really died from scurvy?". Pavlos Plessas' rebuttal to the latter article is published here from a letter to Theo Dirix. |

...continued from: An answer regarding the death of Andreas Vesalius (1)... 8. Echtius’ treatise was only published after his death in 1556 This is incorrect. Echtius was alive almost a decade after that and heard Boucherus describe Vesalius’ death with his own ears. The treatise was first published in 1564, the year of Vesalius’ death, albeit was wrongly attributed to Wierus. 9. Echtius believed scurvy was caused by a blocked spleen, leading to an excess of black bile Echtius believed that an excess of black bile (melancholic humour) caused scurvy. He wrote that in addition to eating preserved foods and mouldy biscuit, and drinking foul water, the following conditions led to an excess of black bile: warm air, lack of sleep, hard manual work, anxiety and fevers. Each one individually could cause scurvy even if the diet was good . The reasons for Vesalius’ illness as indicated by the sources are: eating rotten biscuit, drinking corrupt water, hot weather and extreme worrying. Please compare with the list of causes given by Echtius in his treatise. 10. It is claimed that extreme fear and irrational behaviour … are well known early symptoms [Plessas]. This is not the case |

I quote Rev. Richard Walter of the Anson expedition, who saw many of his shipmates die from scurvy: This disease is likewise usually attended with a strange dejection of spirits; and with shiverings, tremblings, and a disposition to be seized with the most dreadful terrors on the slightest accident (4).
Why allegedly? I quote from the study: The personality changes occurred at an earlier stage of depletion than the psychomotor changes, which did not appear until obvious clinical scurvy was present (5). So the study does claim that personality changes are amongst the first symptoms of scurvy, the very first as a matter of fact. According to figure 3 of the study the MMPI T-scores started increasing when the level of Vitamin C in the body was at the equivalent of 761 mg. Clinical signs of scurvy became apparent only when the level went down to 300 mg. |
