Unveiling the Secrets of Renaissance DIY Science: A Proteomics Journey
The Renaissance DIY Revolution
Imagine a time when people were more like DIY scientists than witches from Macbeth. In the 16th century, home remedies were all the rage, and medical manuals were incredibly popular. Stefan Hanss, an early modern historian, reveals that these manuals were not just theoretical books but practical guides filled with tinkering and experimentation. And the proof is in the protein traces left behind by these reader-practitioners.
A Multispectral Imaging and Proteomics Adventure
Hanss and his interdisciplinary team of archaeologists, chemists, historians, conservators, and materials scientists have embarked on a fascinating journey. They've analyzed trace proteins from the fingerprints of Renaissance people who rifled through medical manuals, revealing a treasure trove of insights. This groundbreaking research, published in The American Historical Review, marks the first time proteomics has been used to analyze Renaissance recipes, enhanced by in-depth archival research.
The Renaissance Experimentation Culture
Hanss highlights the key element of Renaissance culture: experimentation. It wasn't just about book-learned knowledge but hands-on practical knowledge. The manuscripts are filled with scribbled marginalia, indicating that people were actively engaging with the recipes and making personalized notes. This DIY approach to science is a significant shift in how knowledge was constructed during that era.
Analytical Techniques: Unlocking Historical Secrets
The team's work builds upon a growing trend of using analytical techniques to create historical molecular records. For instance, studying microbial species on artworks can help preserve aging art. In a previous study, scientists analyzed microbes on Leonardo da Vinci's drawings using Nanopore sequencing, revealing unique microbiomes for each drawing.
Mass Spectrometry-Based Proteomics: A Powerful Tool
Mass spectrometry-based proteomics is a relatively new technique that provides detailed characterizations of protein residues and accumulated damage. It's so sensitive that it requires less sample material and can characterize all proteins in a sample, not just predefined ones. This approach has been used to discover beer byproducts as canvas primers for Danish Golden Age artists.
The Microscopic Records Event and the Milan Discovery
Hanss's interest in proteomics began with an event called 'Microscopic Records,' where experts in various fields and historians gathered. Researchers had extracted proteins from archived manuscripts in Milan, and Hanss envisioned applying this to Renaissance recipes. This sparked the idea of sampling and identifying biochemical traces of materials, a groundbreaking approach.
Analyzing Renaissance Medical Manuals
Hanss and his team focused on two 1531 German medical manuals by Bartholomäus Vogtherr. These manuals, bound together, are part of Manchester's John Rylands Research Institute and Library collection. The recipes include domestic remedies for various illnesses, written in the vernacular and targeted at the common populace.
High-Resolution Photography and Multispectral Imaging
The first step was high-resolution photography, followed by multispectral imaging (including infrared and UV wavelengths) to recover faded handwriting. One scribbled note revealed a treatment for ulcers using a mixture of viola and scorpion oil. They then sampled pages for proteomics analysis, focusing on areas where users would leave fingerprints.
Proteomics Results: A Window into Renaissance DIY Science
The proteomics results confirmed the presence of popular ingredients and provided insights into how people responded to remedies. Traces of immunoglobulin, lipocalin, and lysozyme indicated an active immune response. One remarkable finding was the recovery of collagen peptides from hippopotamus teeth, suggesting the global circulation of exotic ingredients.
Antimicrobial Proteins and Renaissance Health
The team also discovered antimicrobial proteins like dermcidin, which kills E. coli and yeast infections. These findings offer a fascinating glimpse into the medical practices and responses of Renaissance people.
Expanding the Interdisciplinary Approach
Hanss is thrilled with the initial results and plans to extend this interdisciplinary approach to other medical manual collections. He aims to improve dating methodologies and asks new questions, building upon the success of this project. The ingredients for success are there, and the team is ready to unlock more secrets of Renaissance DIY science.
