Lisa Ellis, conservator at the Art Gallery of Ontario, joins us to share her international investigation into the Boxwood micro-sculptures. Crafted 500 years ago, little is known about who made the astonishingly detailed wooden items that often bear a religious theme, and Lisa is working with NASA, the MET, the Rijksmuseum, and other institutions to use X-rays, Micro-CT Scanners, and other technologies to unlock the mystery in time for an exhibition that will debut in Toronto Nov. 5th and then travel to New York and Amsterdam.
