Rush was, in truth, a spirit of darkness, whose mission it was to wander on the earth tempting and impelling people to do evil. Perceiving that the internal condition of a certain abbey was well suited to his purpose, he presented himself at its gates in the disguise of a youth who wanted employment, and was received as an assistant in the kitchen, but he pleased the monks best by the skill with which he furnished them all with fair companions. At length he quarrelled with the cook, and threw him into the boiling caldron, and the monks, assuming that his death was accidental, appointed Rush to be cook in his place. After a service of seven years in the kitchen--which appears to have been considered a fair apprenticeship for the new honour which was to be conferred upon him--the abbot and convent rewarded him by making him a monk. He now followed still more earnestly his design for the ruin of his brethren, both soul and body, and began by raising a quarrel about a woman, which led, through his contrivance, to a fight, in which the monks all suffered grievous bodily injuries, and in which Brother Rush was especially active. He went on in this way until at last his true character was accidentally discovered. A neighbouring farmer, overtaken by night, took shelter in a hollow tree. It happened to be the night appointed by Lucifer to meet his agents on earth, and hear from them the report of their several proceedings, and he had selected this very oak as the place of rendezvous. There Brother Rush appeared, and the farmer, in his hiding-place, heard his confession from his own lips, and told it to the abbot, who, being as it would appear a magician, conjured him into the form of a horse, and banished him. Rush hurried away to England, where he laid aside his equine form, and entered the body of the king's daughter, who suffered great torments from his possession. At length some of the great doctors from Paris came and obliged the spirit to confess that nobody but the abbot of the distant monastery had any power over him. The abbot came, called him out of the maiden, and conjured him more forcibly than ever into the form of a horse.
