The Druids[26] were the interpreters of divine things to the Celtic conscience. They shared with the knights the administration of public affairs, expounded the ceremonial law and determined the times and modes of its application. Cæsar states, but not on good authority, that Druidism originated in Britain, and Tacitus, who lived towards the end of the first century of the Christian era, that Anglesey was its religious centre. An impressive picture is given of the scene (A.D. 60) which was presented to the army of Suetonius Paulinus preparing to attack that venerable sanctuary. “Along the shore was seen a dense line of armed warriors, while women were rushing about between the ranks garbed like the Furies, in black gowns, their hair flowing loose, and torches in their hands. The Druids were visible in the rear offering sacrifices to their gods, raising their hands to heaven, and calling down dire imprecations upon the head of the invader.”[27] Of Druidical worship in Cornwall there is no direct evidence.[28] The kinship and intercourse and close relations, however, which subsisted between Cornwall, Wales and Ireland leave no room for doubt that Druidism was its religious system. It should be needless to observe that its megalithic remains, dolmens, circles, and the like, which were erected many centuries before the Celts appeared in Britain, had originally no connection with Druidism and that there is no evidence to show that they ever became identified with it. Without stopping to compare Irish and Gaulish Druidism with that of Britain there is one point which claims attention and which, whether Druidical or essentially primitive and sporadic, bears witness to the existence of a cult which, occurring in Ireland, could not have been introduced by the Romans.
