Note 520 — Chapter VII · THE CASTLES OF THE NORMANS IN ENGLAND (continued 2)
Reading edition
“Condidit castellum in excelso preruptæ rupis super Twedam flumen, ut inde latronum incursus inhiberet, et Scottorum irruptiones. Ibi enim utpote in confinia regni Anglorum et Scottorum creber prædantibus ante patebat excursus, nullo enim quo hujusmodi impetus repelleretur præsidio locato.” Symeon of Durham, R. S., i., 140.
