Liber generationis Jesu Christi
“Lo, it is nearly 350 years that we and our fathers have inhabited this most lovely land, and never before has such terror appeared in Britain as we have now suffered from a pagan race, nor was it thought that such an inroad from the sea could be made. Behold, the church of St. Cuthbert spattered with the blood of the priests of God, despoiled of all its ornaments; a place more venerable than all in Britain is given as a prey to pagan peoples.”
