Oswy faithfully kept his word. He set apart twelve estates to be thenceforward monastic property--six in the north, and six in the south of his double kingdom. He then took his daughter Elfleda, who was but yet a year old, and consecrated her to God by the vow of perpetual virginity. Her mother, the daughter of Edwin, first Christian king of Northumbria, had been also dedicated to God from her birth, but only by baptism, and as a token of the gratitude of a still pagan father for the protection of the Christian's God. The daughter of Oswy was to be the price of a yet higher gift of heaven--the conclusive victory of his race, and of the Christian faith in his country; the sacrifice reminds us of that of Jepthah's daughter; but she, far from desiring to escape her vow, showed herself, during a long life, always worthy of her heavenly Bridegroom. The king took her from the caresses of her mother, to intrust her to the abbess Hilda of Hartlepool, who nearly ten years before had been initiated into the monastic life by S. Aidan. In 658, when Elfleda was three years old, S. Hilda founded her monastery of Streaneshalch, now called Whitby, and moved thither with her little spiritual daughter. Elfleda was scarcely twenty-five years of age, when S. Hilda died, and she was called to succeed her as abbess of Whitby. She is described by Bede as a most pious mistress of spiritual life. But like all the Anglo-Saxon princesses whom we meet within the cloister at this epoch, she did not cease to take a passionate interest in the affairs of her race and her country, and to exercise that extraordinary and salutary influence which was so willingly yielded by the Anglo-Saxon kings and people to those princesses of their sovereign races who became the brides of Christ. She maintained that reverent and affectionate relation with S. Cuthbert which had been maintained by S. Hilda.
