He therefore resolved to make such a blow at the head as must of course disable all the inferior members.
The island then called Mona, now Anglesey, at that time was the principal residence of the Druids.

Here their councils were held, and their commands from hence were dispersed among all the British nations.
Paulinus proposed, in reducing this their favorite and sacred seat, to destroy, or at least greatly to weaken, the body of the Druids, and thereby to extinguish the great actuating principle of all the Celtic people, and that which was alone capable of communicating order and energy to their operations.
