At Oxford the attitude of the Jewry towards the national religion showed a marked consciousness of this royal protection. Prior Philip of St. Frideswide complains bitterly of a certain Hebrew with the odd name of "Deus-cum-crescat," who stood at his door as the procession of the saint passed by, mocking at the miracles wrought at her shrine. Halting and then walking firmly on his feet, showing his hands clenched as if with palsy and then flinging open his fingers, the mocking Jew claimed gifts and oblations from the crowd who flocked to St. Frideswide's on the ground that such recoveries of limb and strength were quite as real as any Frideswide had wrought. But though sickness and death, in the prior's story, avenge the insult to his shrine, no earthly power, ecclesiastical or civil, seems to have ventured to meddle with "Deus-cum-crescat." The feud between the priory and the Jewry went on unchecked for a century more to culminate in a daring act of fanaticism on the Ascension-day of 1268. As the usual procession of scholars and citizens returned from St. Frideswide's, a Jew suddenly burst from the group of his comrades in front of the synagogue, and snatching the crucifix from its bearer trod it under foot. But even in presence of such an outrage as this the terror of the Crown shielded the Jewry from any burst of popular indignation. The sentence of the king condemned the Jews of Oxford to erect a cross of marble on the spot where the crime was committed; but even this was remitted in part, and a less offensive place was allotted for the cross in an open plot by Merton College. With the Jewish settlement began the cultivation of physical science in Oxford. The Hebrew instruction, the Hebrew books which he found among its rabbis, were the means by which Roger Bacon penetrated to the older world of material research. A medical school which we find established there and in high repute during the twelfth century can hardly have been other than Jewish: in the operation for the stone, which one of the stories in the 'Miracles of St. Frideswide' preserves for us, we trace the traditional surgery which is still common in the East. But it is perhaps in a more purely material way that the Jewry at Oxford most directly influenced our academical history. There as elsewhere the Jew brought with him something more than the art or science which he had gathered at Cordova or Bagdad; he brought with him the new power of wealth. The erection of stately castles, of yet statelier abbeys, which followed the Conquest, the rebuilding of almost every cathedral or conventual church, marks the advent of the Jewish capitalist. No one can study the earlier history of our great monastic houses without finding the secret of that sudden outburst of industrial activity to which we owe the noblest of our minsters in the loans of the Jew. The bonds of many a great baron, the relics of many an abbey, lay pledged for security in the "Star-chamber" of the Jew.
