Researchers hailing from the University of Catania, SpringStyle Tech Design Ltd, Romania National Archives, and Politecnico di Milano, recently delved into letters penned by Vlad Drăculea and have since uncovered intriguing evidence pointing to a range of ailments the historical figure suffered.
The team's study meticulously examined three letters written by Vlad Drăculea, with a focus on the chemical residues left behind by the act of writing.
By employing an innovative technique involving ethylene-vinyl acetate, the researchers extracted material from the paper without causing damage. Subsequent mass spectrometry analysis revealed a wealth of information about the prince's potential health issues.
Among the most astonishing findings is the indication that Vlad the Impaler may have suffered from a rare genetic disorder known as ciliopathy, a condition that can compromise various aspects of cell function and organ health. Additionally, evidence of inflammatory disease was detected, suggesting potential afflictions of the respiratory tract and skin.
Perhaps the most captivating revelation is the suggestion that Vlad the Impaler experienced hemolacria, a rare condition in which blood mingles with the fluid in tear ducts, leading to the emergence of blood-tinged tears. The startling detail could offer a new perspective on the historical accounts of the prince's demeanor and experiences.
The findings of the study were published in Analytical Chemistry journal.
