In 2012, Cornelison published her first single-authored book, “Art and the Relic of St. Antoninus in Renaissance Florence,” an interdisciplinary examination of the history and visual culture of the relic cult devoted to Florence’s sainted archbishop, Antoninus Pierozzi. This book demonstrated for the first time that popular and civic devotions to the saint’s remains, which were entombed in the Florentine church of San Marco, were key elements of Florence’s sacred cityscape and generated a significant visual tradition.
