Renaissance DIY science: People tested, tweaked home remedy recipes

In the 16th century, individuals took on the role of DIY scientists, crafting home remedies for ailments ranging from hair loss to kidney stones, much like the famed characters in Shakespeare's works. According to Stefan Hanss, a historian from the University of Manchester, medical manuals aimed at everyday people were widely circulated during this period. These 'reader-practitioners' modified the various concoctions, making personalized adjustments and jotting down notes in the margins. A groundbreaking study conducted by a team of archaeologists, chemists, historians, conservators, and materials scientists has shed light on this fascinating aspect of history. They examined trace proteins left behind on the pages of medical manuals, marking the first time proteomics has been applied to Renaissance recipes. Published in The American Historical Review, their findings reveal how intertwined scientific inquiry and practical knowledge were during this era. Hanss emphasized the abundance of recipes from this time, which included not only medical and cosmetic formulations but also culinary traditions. The manuscripts were often adorned with scribbled notes from users, indicating a vibrant culture of experimentation. This period marked a significant shift in knowledge construction, blending theoretical learning with hands-on practice. Additionally, modern analytical techniques have emerged that allow historians to create molecular records of the cultural context surrounding various artworks. For instance, research conducted in 2020 on Leonardo da Vinci’s drawings utilized advanced sequencing methods to identify distinct microbial communities present on the artworks, showcasing how science continues to unlock the mysteries of the past.
