One other circumstance in the history of this man, whose life was a series of bold undertakings, serves to illustrate the superstitions of the times. When King William had besieged the island of Ely, which was the headquarters of Hereward and his large following of Saxon warriors, and had failed to subdue them, he gave heed to the counsel of one of his courtiers, to have recourse to a celebrated witch for aid in the destruction of his foes. Hereward, to spy upon his adversary and discover his plans, disguised himself as a potter, and stopped at the house of the old woman whose magic was to be used against him; that night he followed her and another crone out into the fields, where they engaged in their curious rites. From their conversation he learned of the scheme against him, which was to have a platform erected in the marshes surrounding the island; the hag was to repeat thrice her charm, when he and his followers would be destroyed. Accordingly, when the platform was erected and the besiegers drew as near as they could, expectantly awaiting Hereward's destruction, he and his companions, under the cover of the brush, crept close to the platform and, taking advantage of the favorable direction of the wind, set fire to the reeds. The witch, who was about to repeat her charm for the third time, leaped from the platform in terror, and was killed, while in the panic many of the soldiers lost their lives by fire or by water. The scene here depicted bears a remarkable similarity to the weird rites of the ancient British Druidesses, and doubtless represents a continuance of the mysteries of that order, which came down in forms of magic and witchcraft through many centuries. This glimpse of the witchcraft that was to become more prominent, or at least with which we become more familiar at a later period, will suffice to show that the plane of general intelligence was not yet high. Education was limited to subjects that have no special interest for us to-day. Such as it was, it was accessible to the lower classes as well as to the upper. There were schools connected with the churches and the monasteries. Apparently, there was no distinction in the subjects pursued by the sexes, excepting in the case of the nobility, whose sons were trained for the positions they were to occupy. It would appear that some priests were so zealous for the prosperity of their schools that they sought to entice scholars from other schools to their own. A law to correct the practice provided "that no priest receive another's scholar without leave of him whom he had previously followed." Latin was in the list of the studies pursued by the ladies, but few could read in the vernacular.
