example of Arban, who entered upon the neighbouring see of Llandaff in 1107, and reared a mother church for his diocese. Finally, Ripon also saw the masons busily at work almost through the century. First Thurstan, Archbishop of York in 1114, began the enlargement of the Abbey Church, and after him Archbishop Roger (1154-1181) entirely rebuilt it. But the record of the churches re-built during this century by no means exhausts the tale of work performed during that time. At Winchester, for example, in 1107 the central tower fell, necessitating the building of a new one. Lucy, bishop here from 1189 to 1205, erected a new Lady Chapel and made other alterations. At Hereford, too, operations were going forward almost throughout the century, the bishops Reynelm (1107-1115) and Betun (1131-1148) being especially energetic in pressing them on; and the closing years of this period saw the rearing of the eastern transepts. At this time also the beautiful Galilee Chapel was added to Durham Cathedral; Ely was consecrated in 1106, and towards the end of the century received its central tower and other additions; and S. Albans, moreover, had a facade built on its western front by John de Cella. The chronicle of the damages by fire during the twelfth century is not complete without mentioning that S. Paul's, London, which was re-building during a large portion of that time, was injured by it in 1136; and the same foe destroyed the roof of Worcester Cathedral in the early days of the century. The period which our rapid survey has so far covered embraces broadly the eras of the Norman and of the so-called Early English architecture. In the thirteenth century the Decorated Style came into being, and with its rise arose also the desire for greater richness of ornament even in those churches which had already, to all appearances, been completed. On all hands, therefore, in this new century, we find the pulling down of portions of the stern Norman work and the substitution of lighter and more graceful designs. The great work of the thirteenth century, however, was begun before the birth of the more florid style, and shows little trace of the dawning of its influence. Salisbury Cathedral was begun in 1220, the work commencing, as was usual, at the eastern end and advancing westward. The whole was proceeded with continuously, and since its completion no alteration of any importance has been made in it. Other cathedrals in England exhibit in almost every case a conglomerate of several orders of architecture, blended generally with great skill, but necessarily lacking to some extent in unity of design in consequence. In Salisbury we have one complete and splendid example of English architecture of the best period, carried out from beginning to end with unbroken unity of purpose.
