According to their earliest records, the Picts of the British Isles claim a Thracian origin. Herodotus tells that the nobles of the Agathyrsi tattooed themselves, and the claim of the Picts to be Agathyrsi is on record, and shows their acquaintance with Thracian tradition. Orpheus, the bard who made trees dance to his music, was a Thracian, and early Irish story says that the children of Nemed were almost the earliest invaders of Ireland. A dancing grove can only apply to those worshippers who frequented such localities. These topics and many, many more can be found in this work on the traditions of the Scots, Picts and Cymry.
