On October 23, the Clark Library welcomed Professor Thiago Sevilhano Puglieri (Art History, UCLA) for an engaging lecture that illuminated the scientific and ethical dimensions of cultural heritage research. Drawing on his interdisciplinary expertise in art history, chemistry, and conservation, Puglieri guided attendees through the analytical methods chemists use to study cultural objects and the nuanced ethical considerations that shape this work, offering insight into the questions conservators ask, the tools they rely on, and the decision-making frameworks that guide responsible analysis. Puglieri then turned to the investigation of Indigenous cultural heritage, highlighting the unique protocols, community relationships, and cultural responsibilities essential to this work. Thoughtful and engaging questions from the audience provided a lively discussion.
The session concluded with a demonstration of chemical analysis techniques, giving participants a rare opportunity to observe scientific investigation in real time. A metal box with gold details, from the Clark collection, surprised everyone as we discovered that the gold detailing was actually copper. Realizing the necessity of asking questions about the materials, technologies, and collaborative practices are what define this interdisciplinary field.
This thought-provoking event offered attendees a deeper appreciation of the complexities—and responsibilities—at the heart of heritage science today.
Professor Puglieri kindly allowed his lecture to be posted on the Center’s YouTube channel, and it is now available for viewing.
