The three articles in this “In Focus” section originated as papers delivered at Material Matters, the tenth annual conference of the Atlantic Mediaeval Association held at Dalhousie University and the Art Gallery of Nova Scotia, September 22–23, 2017. The conference itself was inspired by, and timed to coincide with, a major exhibition at the Art Gallery of Nova Scotia — Centuries of Silence: the Discovery of the Salzinnes Antiphonal, which ran from May 2017 to January 2018 and was curated by Judith Dietz. The three papers, by Marianne Gillion, Annaliese Renck and Sébastien Rossignol, situate the Salzinnes Antiphonal in myriad ways, by focusing on books from the decades stretching across the turn of the sixteenth century, from the 1490s to the 1510s.
