 There is virtually no evidence to shed light on the practice of religion in Wales during the Roman era, save the anecdotal account of the strange appearance and bloodthirsty customs of the druids of Anglesey by Tacitus during the conquest of Wales.It is fortunate for Rome's reputation that Tacitus described the druids as horrible, else it would be a story of the Roman massacre of defenceless, unarmed men and women.The likelihood of partisan propaganda and an appeal to salacious interests combine to suggest that the account merits suspicion.
