Prof. Louisa Matthew

When art historian Louisa Matthew finished the only economics class she ever took in college, she thought she was done with things like supply and demand. “If you had told me I'd be studying economics after that,” she said, “I would have fainted.”


But Matthew finds herself immersed in economics – the business of art – for her research on paints used by Venetian Renaissance artists.


Her research is chronicled in a recent issue of Science News.


Renaissance paintings from 15th- and 16th-century Venice have long been known for their vivid and glowing colors. But what makes them so?


Matthew had been trying to answer that question in the dusty state archives of Venice, where she pores over nearly-illegible documents handwritten in archaic Italian. One piece of paper, a store inventory from 1534, confirmed her long-held suspicion that the color vendors of the day sold painting supplies to a wide variety of craftspeople who used colorants and related supplies – not just to easel painters but to anonymous painters of furniture, masks, textiles and even the inside and outside walls of houses.


The discovered document spurred Matthew's colleague Barbara Berrie, a conservation scientist at the National Gallery in Washington, to take another look at some paint samples from works by Venetian artists. She discovered glass particles mixed with the paint, which seem to have been used for a variety of purposes: as paint extender, dryer and perhaps to add luster to paint colors.


 “I hypothesized from the beginning that shops were patronized by all sorts of craftspeople – glassmakers, dyers, masons and gondola painters,” Matthew said. “Now we can talk about Venice as a nexus for sharing ideas and teaching across professions.”


Teaching across professions is nothing new to Matthew. She has long called on colleagues from across campus to help in her work. “I understand how exciting these connections are,” she said. “That's what's great about teaching here.”


Matthew has team taught a course — and hike — on the Camino de Santiago, a 1,000-year-old pilgrimage route in Spain, with Prof. Victoria Martinez of modern languages; and a course on Renaissance Florence with Prof. Steve Sargent of history. She is planning a new GenEd course on the science of art conservation with colleagues in the chemistry department.
