In the 1790s Iolo Morganwg produced a set of “ancient texts” that presented the lineage, organization, cosmology, and rituals of Druidry. He was part of a movement that was asserting the vitality of Welsh language and culture as a contribution to the contemporary form of British multiculturalism. Or rather, perhaps this was the first modern attempt to counter the hegemony of English language and culture over the peoples of the British Isles, and the first experiment in celebrating the plurality of British identity and culture. Rituals were performed on Primrose Hill in London as well as at other locations of alleged significance to ancient Druids and their descendants in every generation, especially in Wales. Some of these rituals (re)claimed for Druidry the henge monuments and stone circles that decorate the land; others required the erection of new standing stones and the construction of new venues for the performance, display, and improvement of bardic arts. Iolo was not alone; his traditions and liturgies found ready acceptance not only among Welsh groups but also among English, Cornish, and Breton celebrants of antique and noble rites and poetry. Perhaps the acceptance of his texts and his Druidry was facilitated (among the Welsh at least) by their fit with the pervasive nonconformist Christianity of Wales, and (among some of the English at least) by their intersections with aspects of contemporary esotericism.
