 The scholar of religion Graham Harvey believed that these specific instruments were preferred by modern Druids because many of them were Irish in origin, and therefore gave a "Celtic flavour, seemingly invoking the Iron Age", the period during which the ancient druids lived.Groups like the British Druid Order have established their own "gorseddau".Unlike the Welsh cultural gorseddau, these Druidic events often allow anyone to perform as a bard if they are inspired to do so.
