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.
