Jill Magid is certainly dedicated to her artistic practice, going to rather insane extremes while trying to access the archives of Mexican architect Luis Barragáns. After being repeatedly refused permission to see them, Magid actually exhumed some of Barragán’s ashes, had them manufactured into a diamond ring, and offered the jewel to the keeper of the archive, the wife of the heir to the Vitra furniture company. (The stunt caused something of a kerfuffle in Barragán’s native Mexico, though Magid had his family’s full permission to exhume the ashes.) Winner of this year’s prestigious Calder Prize, Magid recently began screening The Proposal, a feature-length documentary about her attempts to see the Barragán archive. Her free public talk is part of the RISD photo department’s annual TC Colley lecture series.
