Written and presented by renowned novelist and broadcaster Frank Delaney, 'The Celts' is the landmark BBC documentary series that explores the origins, growth and cultural legacy of this most fascinating group of tribal societies, living around two thousand years ago across many areas of Europe. From the earliest archaeological finds, through the Iron Age and Roman eras, right up to their lasting influence on popular culture in modern times, Delaney's in depth investigation is detailed, wide-ranging and always accessible. Featuring interviews with leading academics including Barry Cunliffe and Proinsias Mac Cana, the programme also consults contemporary cultural figures aware of the Celtic influence in their work, such as comedian Dave Allen. This unique and engaging series is also notable for launching the solo career of musician Enya. The ex-Clannad singer was commissioned to compose the score for the series, writing and singing the haunting theme song, while two episodes include the music videos for 'I Want Tomorrow' and 'Aldebaran'.
