"What white, what purple fritillaries The grassy harvest of the river-fields, Above by Ensham, down by Sandford, yields, And what sedged brooks are Thames's tributaries." Whichever way you choose you will turn now and again to look back upon the spires and towers of Oxford and Radcliffe's dome, clustering together among rich gardens and noble trees, watered by the winding, willow-fringed Cherwell and the silver stream of Isis, "rivulets," as Wood quaintly phrases it, "which seem to the prying spectator as so many snakes sporting themselves therein." And so gazing you will let your fancy roam and think of her past history and her future influence on thought and the affairs of State. * * * * * Within fifty years of their first landing the Northern hordes had conquered the greater part of Britain. Mercia, the border kingdom of the marches, had been formed, embracing the site of Oxford; its heathen King Penda had lived and died, the Mercians had embraced Christianity, and Dorchester had become the seat of a Christian bishop. But it was not till the eighth century A.D. that the vill of Oxford, an unfortified border town on the confines of the kingdoms of Mercia and Wessex, came into existence; it was not till the year 727, one hundred and thirty years after S. Augustine's mission to England, that a religious community settled there. The history of that settlement is bound up with the story of S. Frideswide--Fritheswithe, "the Bond of Peace." For although the details of the legend are evidently in part due to the imagination of the monastic chroniclers, yet there is no reason to doubt the main facts of time and place.
