Proceedings of the Harvard Celtic Colloquium, 39 includes the 2019 J. V. Kelleher lecture by Máire Ní Mhaonaigh which centered on medieval Irish chroniclers' conceptions of past and present events in the wider world. Other papers expand the scope of this volume from the medieval into the early modern period, and into the early twentieth century.

This volume of Proceedings of the Harvard Celtic Colloquium is graced with two J. V. Kelleher lectures: the 2019 lecture by Máire Ní Mhaonaigh on Irish chronicles and the 2021 presentation by Ruairí Ó hUiginn assessing the Irish genealogical corpus in its sociological context. It also includes Georgia Henley's 2021 keynote on the differing literary receptions in Norman Ireland and Wales of Geoffrey of Monmouth's history of Britain and related prophecies. Other articles in Volume 40 survey a wide array of topics in Celtic Studies, centering on Irish and Welsh material with the smaller language areas appearing as well, and ranging from medieval to modern times. While most are literary or linguistic in their focus, some historical context is also provided.

This is a selection of papers on all facets of Celtic studies from the Harvard Celtic Colloquium conference in 2011.

Kelleher Lecture "The Red Sword, the Sickle and the Author's Revenge: Welsh Literature and Conflict in the Seventeenth Century."
