Earl Warren, who came into possession about 1068, found the place already well fortified. His son and grandson were the ones who, it is supposed, constructed the outer walls, with their various buildings for domestic purposes, comprising a hall, kitchen, chapel, etc. These cover a large area, but present no features of extraordinary interest. The inner tower, or keep, however, is one of the most remarkable structures in England. It is a huge cylindrical tower built of grey limestone on a base of solid natural rock. It formerly rose to a height of one hundred and twenty feet, and is now about ninety feet high. It is sixty-six feet in diameter at the base, and is supported by six massive buttresses, each fifteen and one half feet broad and extending outward about nine feet. The walls themselves are nearly fifteen feet in thickness. The only entrance is a door, twenty feet above the ground, originally reached by an outside stair connecting with a small drawbridge.

The rooms beneath the main floor were used for the storage of provisions and in the centre was a well, said to have been one hundred and five feet deep. There was then ample provision to resist a siege, lack of food and water being the only danger to be feared, inasmuch as the catapults and other engines of war of that period would be powerless against the massiveness of such a castle. The upper rooms are built within the walls and reached by narrow stairways. The main floor was probably used by the lord of the castle with his family and guests; the rooms above were occupied by the ladies of the household, and on the same floor was a small oratory or chapel, hexagonal in shape and about eight feet wide. The top floor contained the kitchen and the sleeping-rooms of the garrison. The six buttresses projected above the level of the parapet, forming turrets, convenient for defence. These have now disappeared. The parapet floor is still accessible, and from it a fine view is obtained of the surrounding country.

The Castle of York, where Prince John is supposed to have feasted the nobles and leaders after the exciting scenes of Torquilstone, and where De Bracy announced to him that Richard was really in England, was the Norman fortress built by William the Conqueror in 1068, some portions of which are now incorporated in the building known as Clifford's Tower. A substantial rectangular structure stands between two ancient and ruined turrets, which lean outward, looking as though the stronger building were trying to usurp the hill on which they stand and push his feebler brethren out of the way. This castle was the scene in 1190 of a terrible massacre of the Jews. Two rich Jewish bankers, Joses and Benedict, attended the coronation of Richard I. In a general attack upon the Jews, Benedict was killed, but Joses got back to York. The house of Benedict in York was plundered and his wife and children murdered. Joses rallied the other Jews, who took refuge, with their property, in the castle. The governor ordered an assault, and the Jews, finding themselves unable to hold the citadel, set fire to the buildings, put to death all their relatives, and killed themselves, over five hundred lives being sacrificed. This incident throws some light upon the state of mind of the wealthy Isaac, who was a resident of the city of York.

'Ivanhoe' closes with the wedding of Wilfred and Rowena, 'celebrated in the most august of temples, the noble minster of York.' The cathedral as it stands to-day is, indeed, noble. Perhaps it cannot properly be called the largest in England; Winchester Cathedral is longer, and Lincoln's towers are higher; but in the length of its choir and nave, the breadth of its transepts, the height of the great pointed arches supporting the roof, and the massive grandeur and dignity of the whole, whether viewed from the exterior or the interior, it is unsurpassed by any other cathedral in England and by few on the continent.

It was not in this magnificent temple, however, that the wedding took place, and perhaps if we could see a picture of the old Norman church which stood on the site in 1194, we might not think of it as 'a noble minster.' The church of that period was the structure built by the first Norman Archbishop of York, with the addition of the choir, erected a century later. In the crypt of the present cathedral some bits of the walls of these early buildings are still preserved. They replaced the first stone church, built about 633, which had superseded the original wooden church, built by Eadwine, King of Northumbria, then the most powerful monarch in England. The minster was, therefore, more than five centuries old even in the period of 'Ivanhoe.'

Of the characters in the novel, King Richard and his brother John were of course historical. Cedric and Athelstane were types of the Saxon nobles who still resented the intrusion of the Normans. Front-de-Boeuf represents a class of Norman noblemen who did not hesitate at any deed of villainy to accomplish their selfish purposes. Brian de Bois-Guilbert typifies the chivalry which professed great zeal for the Christian religion, but used it as a cloak to cover motives of vengeance or other base purposes. Prior Aymer stands for the wealthy churchman and Isaac of York for the Jewish banker, upon whom all classes, kings, barons, and churchmen, were obliged to depend for the accomplishment of their various plans. Robin Hood, Friar Tuck, and the men in Lincoln Green were borrowed from the ballad poetry of the Middle Ages. All of these were introduced to perfect the picture of the conditions of social and political life in the reign of King Richard.

One character only found a place in the novel for another reason. The story of Rebecca reveals an interesting incident in the life of Washington Irving. When the American author visited Sir Walter at Abbotsford a feeling of mutual respect and admiration quickly sprang up between them and developed into a friendly intimacy. In the course of their conversations, Irving told Sir Walter something of the character of Rebecca Gratz, a young woman of Jewish family, living in the city of Philadelphia. One of this lady's brothers was a warm personal friend of Irving's, who was always a welcome guest at their home. One of Rebecca's dearest friends was Matilda Hoffman, Irving's first and only love. This estimable young woman died at the early age of eighteen, tenderly nursed to the end by her friend Rebecca, in whose arms she expired.

Rebecca Gratz is described as a very beautiful girl. 'Her eyes were of exquisite shape, large, black, and lustrous; her figure was graceful and her carriage was marked by a quiet dignity,—attractions which were heightened by elegant and winning manners. Gentle, benevolent, with instinctive refinement and innate purity, she inspired affection among all who met her.'[[3]] Although a Jewess, Rebecca Gratz found many companions among the Christians by whom she was held in high esteem. She was interested in all kinds of benevolent work, founded an orphan asylum and a mission Sabbath-School for Hebrew children, and contributed to many charities.

A Christian gentleman of wealth and high social position fell in love with her and his feelings were reciprocated. But Rebecca conceived that duty demanded loyalty to her religion, and her lofty conscientiousness and remarkable moral courage enabled her to maintain her resolution. She refused to marry, in spite of the pain to herself and the bitter disappointment to her lover which the self-denial involved. Her life was devoted to 'a long chain of golden deeds,' until the end came at the good old age of eighty-eight.

Such a story could not fail to capture the sympathetic heart of Sir Walter, and as usual when anything appealed strongly to him, he wove it into a novel at the earliest opportunity, later writing to Irving, 'How do you like your Rebecca? Does the picture I have painted compare well with the pattern given?'
