A graduate of theUniversity of California, Berkeley, where he received his higher degrees (B.A. in English, 1967; PhD in Comparative Literature, 1972), Niles taught for an initial four years as Assistant Professor of English atBrandeis University. He then was invited to join the faculty of the Department of English at the University of California, Berkeley, where he remained for twenty-six years until taking early retirement. In 2001 he joined the faculty of theUniversity of Wisconsin–Madison, where he taught for ten years in the Department of English, was named the Frederic G. Cassidy Professor of Humanities, and was a Senior Fellow at the UW Institute for the Humanities. After his retirement from UW-Madison in 2011 he has remained active in research as Professor Emeritus at both UC Berkeley and UW-Madison.
Niles is the author of nine books on Old English literature and related topics. He has edited or co-edited another eight books, in addition to upwards of sixty scholarly articles and other publications. His first book,Beowulf: The Poem and Its Tradition (1983), ascribes the poem's strengths to its grounding inGermanic heroic legend and the oral traditions ofalliterative verse cultivated in early medieval England.[1]
During the 1980s he conducted fieldwork into singing and storytelling traditions inScotland, particularly amongScottish Traveller groups, including the noted storytellerDuncan Williamson. This research led first to his bookHomo Narrans: The Poetics and Anthropology of Oral Literature (1997)[2] which argues forstorytelling as a defining characteristic of the human species, and later to his bookWebspinner: Songs, Stories and Reflections of Duncan Williamson, Scottish Traveller (2022), a portrait of a single gifted tradition-bearer.[3][4] In 2005 he taught a seminar at theNewberry Library, Chicago, on the early history of Old English studies. This became the kernel of his 2015 bookThe Idea of Anglo-Saxon England 1066-1901,a sustained account of the evolution of the study ofOld English literature, theOld English language, and theAnglo-Saxons from its beginnings to the death of Queen Victoria in 1901;[5][6] and to his bookOld English Literature: A Guide to Criticism (2016), which carries the literary side of the investigation into the twenty-first century.[7]
His researches into the archaeology and prehistory of early Northwest Europe led to the jointly-authored publicationBeowulf and Lejre (2007), which centers on the prehistoric Danish site at the present-day hamlet ofLejre, Zealand, where much of the imagined action of the Old English poemBeowulf is set.[8] Niles argues that the origins of theBeowulf story can be traced to the topography andlegends associated with this monumental landscape.
His 2019 bookGod’s Exiles and English Verse: On the Exeter Anthology of Old English Poetry is the first integrative book-length critical study of the earliest anthology of English-language poetry, theExeter Book, a late-tenth-century collection that includes such Old English poems asThe Wanderer andThe Seafarer.[9] Niles argues for the structural and thematic coherence of this anthology as a product of the late-tenth-centuryEnglish Benedictine Reform.[10]
Beowulf and Lejre (2007), with its important contributions byMarijane Osborn and the Danish archaeologist Tom Christensen, has been called "a monumental, provocative, and often delightful book."
Klaeber's Beowulf, 4th edition (2008), which Niles co-edited withRobert D. Fulk and Robert E. Bjork, has been called "a triumph for a triumverate."[11]Medical Writings from Early Medieval England, Volume I (2023), co-edited with Maria A. D'Aronco, has been characterized as "nothing short of a monumental feat."[12]
In 2022, Niles was the honorand of a collection of articles, first published as a special issue of the journalHumanities, and subsequently as the bookOld English Poetry and Its Legacy.
