Eleanor Giraud is a tenured lecturer in ritual chant and song at the Irish World Academy of Music and Dance at the University of Limerick. She will use three Processionals made for use by Dominican nuns held in the Beinecke’s collections as a case study to explore the extent to which the liturgical practices of Dominican sisters followed the norms of their brothers, analyzing these against the authoritative exemplar of the Domincan Processional in Rome to define the types of alterations and adjustments (if any) found in the nuns’ liturgical practices.
