The Celts (usually pronounced  /ˈkɛlts/ but sometimes /ˈsɛlts/, see pronunciation of Celtic) or Kelts were an ethno-linguistic group of tribal societies in Iron Age and Medieval Europe who spoke Celtic languages and had a similar culture.

The earliest archaeological culture that may justifiably be considered as Proto-Celtic is the Late Bronze Age Urnfield culture of central Europe from the last quarter of the second millennium BC. Their fully Celtic descendants in central Europe were the people of the Iron Age Hallstatt culture (c. 800-450 BC) named for the rich grave finds in Hallstatt, Austria. By the later La Tène period (c. 450 BC up to the Roman conquest), this Celtic culture had expanded over a wide range of regions, whether by diffusion or migration: to the British Isles (Insular Celts), France and The Low Countries (Gauls), much of Central Europe, the Iberian Peninsula (Celtiberians, Celtici and Gallaeci) and northern Italy (Golaseccans and Cisalpine Gauls) and following the Gallic invasion of the Balkans in 279 BC as far east as central Anatolia (Galatians).

Frank Delaney (born October 24, 1942) is an Irish novelist, journalist and broadcaster. He's the author of New York Times best-seller "Ireland", the non-fiction book "Simple Courage: A True Story of Peril on the Sea", and many other works of fiction, non-fiction and collections. He was born in Tipperary, Ireland.

In 1970, Delaney began working as a newsreader for the Irish state radio and television network RTE. In the early 1970s he became a news reporter for the BBC in Dublin, and covered an intense period of violence known as The Troubles. After 5 years of reporting on the violence, he moved to London to work in Arts broadcasting. In 1978, he created the award-winning weekly show "Bookshelf" for BBC Radio Four, which covered books, writers and the business of publishing. Over the next five and a half years, he interviewed over 1400 authors including Anthony Burgess, John Updike, Margaret Atwood, Christopher Isherwood and Stephen King. On television, Delaney wrote and presented for Omnibus, the BBC weekly arts series. He served as the Literature Director of the Edinburgh Festival in 1980, and he hosted his own talk show "Frank Delaney" in the early 1980s, featuring an array of cultural and literary personalities. Afterward, he created and presented "Word of Mouth", the BBC's award winning show about language, as well as a variety of radio and television documentaries including specials on James Joyce, Robert Graves, Hemingway in Paris, and the Shakespeare Industry. He presented "The Book Show" on the Sky News satellite channel for many years.

Sir Barrington Windsor Cunliffe, CBE, known professionally as Barry Cunliffe (born 10 December 1939) is a former Professor of European Archaeology at the University of Oxford, a position held from 1972 to 2007. He is now Emeritus Professor of European Archaeology.

Cunliffe's decision to become an archaeologist was sparked off at the age of nine by the discovery of Roman remains on his uncle's farm in Somerset. After studying at Portsmouth Northern Grammar School (now the Mayfield School) and reading archaeology and anthropology at the University of Cambridge, he became a lecturer at the University of Bristol in 1963. Fascinated by the Roman remains in nearby Bath he threw himself into a programme of excavation and publication.

In 1966 he became an unusually young professor when he took the chair at the newly-founded Department of Archaeology at the University of Southampton. There he became involved in the excavation (1961–68) of the Fishbourne Roman Palace in Sussex. Another site in southern England led him away from the Roman period. He began a long series of summer excavations (1969–88) of the Iron Age hill fort at Danebury, Hampshire and was subsequently involved in the Danebury Environs Programme (1989–95). His interest in Iron Age Britain and Europe generated a number of publications and he became an acknowledged authority on the Celts,
