In the diffusion of the sciences of the Saracens throughout Western Europe in the twelfth century, says Professor Haskins in one of his valuable contributions to the English Historical Review, “ England occupies a position of considerable importance. An English scholar, Adelard of Bath, seems to have been the chief pioneer in this movement of study and translation, while the existence of a certain number of dated treatises of his contemporaries and successors makes it possible to follow the spread of the new learning in England with greater definiteness than has so far been attempted elsewhere.” That these Arabian sciences played an important part in the intellectual awakening of England, there cannot be much doubt. Mathematical sciences especially attained a height with the Arabs which had never been reached before in Western Europe.
