Those who find pleasure in inquiries of this description, will join in the regret, that an undertaking like the present was so long delayed. Incalculable had been the advantages, had it but commenced previously to the period of the French revolution. That fearful storm burst with tremendous violence upon the castles of barons, the palaces of kings, and the temples of religion. Many of the most sumptuous edifices, which had mocked the hand of time, and had been respected amidst the ravages of foreign or domestic warfare, were then swept from the face of the earth. Others, degraded, deserted, neglected, and dilapidated, are at this moment hastening fast to their decay. Yet no small portion of what is valuable has been happily left. The two royal abbeys of Caen, though shorn of much of their former grandeur, are still nearly entire. Château Gaillard, the pride of Richard's lion heart, and the noble castles of Arques and of Falaise, retain sufficient of their ancient magnificence, to testify what they must have been in the days of their splendor: the towns and châteaus, which were the cradles of the Harcourts, Vernons, Tancarvilles, Gurneys, Bruces, Bohuns, Grenvilles, St. Johns, and many others of the most illustrious English families, are still in existence; and, of more modern date, when the British Edwards and Henrys resumed the Norman sceptre, numerous buildings of the highest beauty are every where to be met with. In his researches after these, Mr. Cotman had the advantage of being assisted by the kindness of three of the most distinguished antiquaries of the present day, M. le Prevost, M. Rondeau, and M. de Gerville, but particularly by the last, whose friendly help has likewise extended towards the preparing of the letter-press for many of the articles from the western part of the province. It were ungrateful not to acknowledge the assistance derived from Mr. Cohen, in the same department. The value of his aid, which has been most freely contributed, can be duly appreciated by those alone who have had opportunities of judging of the accuracy and extent of his knowledge.
