Chapter 1: The Legacy of Vlad the Impaler

For over a century, readers have been captivated—some might say haunted—by a literary figure that has transcended time. While the name Bram Stoker may not resonate with everyone, his creation, Dracula, certainly does. Many are familiar with the concept of vampires, but the true origins of this myth are more complex.

Some scholars trace the vampire legend back to Vlad III Drăculea, born in Transylvania and later the military governor of Wallachia (modern-day Romania). The name Dracula translates to “son of Dracul,” stemming from the Latin word “draco,” meaning dragon. This title was linked to a chivalric order established by the Holy Roman Emperor in the 15th century to defend against Ottoman invasions.

It is thought that Stoker incorporated Vlad’s infamous brutality into his narrative, drawing from local folklore. Regardless of the accuracy of this assumption, Vlad “The Impaler” was indeed a historical figure, leaving behind three remarkably preserved letters.

Recently, researchers utilized cutting-edge technology to analyze these letters, uncovering centuries-old proteins and peptides that shed light on Vlad’s era and possibly a specific health condition related to blood loss.

Chapter 2: Advanced Techniques in Analysis

The scientists employed high-resolution mass spectrometry (MS), an analytical method that identifies the components of a substance. This technique is particularly adept at detecting proteins and peptides, which can provide insights into the individual who penned the letters. Modern advancements have made it possible to conduct this analysis without damaging historical artifacts.

Using a specialized plastic film (ethylene-vinyl acetate), researchers were able to extract proteins without harming the surface of the letters. Two of the letters were written by Vlad in 1475, while the third dates back to 1457. The letters were largely intact, with the older one having undergone professional restoration, and the newer ones having been preserved in the city of Sibiu's archives.

The research team also utilized UV light to identify areas rich in protein before applying the EVA film, further ensuring the integrity of the letters during the study.

Section 2.1: Findings and Implications

Through a process called deamidation, the scientists differentiated between older and more contemporary proteins and peptides, helping to rule out contamination. While many proteins related to skin were identified, the analysis also revealed associations with respiratory issues and potential eye diseases. Notably, proteins linked to blood and tears were found, leading researchers to speculate that Vlad may have experienced hemolacria, a condition causing bloody tears—a detail echoed in certain folklore.

Interestingly, the analysis did not solely reveal human proteins; several peptides associated with bacteria were also present, including those linked to infections. The presence of Yersinia pestis, the bacteria responsible for the Black Plague, adds another layer to the historical context of Vlad's time.
