The Celts: Rich Traditions and Ancient Myths is a 1987 documentary series that examines the origins, growth, and influence of Celtic culture in Great Britain and throughout Europe.

Delaney also wrote a six-chapter companion book, extended with four tales from Irish mythology.

The series introduced the music of Irish singer Enya to a wider audience.

Enya, formerly a member of the Celtic music group Clannad, was commissioned by David Richardson to compose the score for the series.

The soundtrack album for The Celts was first released in 1987 by BBC Records under the title Enya.
