During this episcopate occurred the trial of the Knights Templars in the chapter-house. A Bull of Pope Clement V., the creature of the French king, who feared the immense power of the knights, pronounced the suppression of the Order in the year 1309. The cruelties with which this was carried out abroad were avoided in this country. The English Templars were put under custody in London, Lincoln, and York. From Lincoln the larger number were transferred to the Tower of London, but Bishop Dalderby was reluctantly compelled to preside at the trial of the others. In order to trace the history of the walls and gatehouses protecting the close, it is necessary to go back a few years. Edward I. had, in 1285, received a petition from the canons, praying that the close might be fortified. Their plea was, that it had become positively dangerous to attend the midnight services of the church, owing to the number of evil-doers who thronged the precincts. The licence from the king in the year 1285 to the dean and chapter, giving them permission to erect the close wall, is still preserved at Lincoln. The wall was commenced, and in the thirteenth year of Edward II. (1319), permission was given for the addition of towers. Double gateways were erected to guard the approaches. Before we come to speak of the upper storeys of the western towers, a few less important matters may be recorded. It is not difficult to see that the tracery which fills the round window, "the Bishop's eye," of the southern limb of the great transept, does not accord in style with its surroundings. The flowing lines mark a period subsequent to the geometrical forms of the Angel Choir, and later by more than a century than the wall in which the window is placed. This window and that in the gable above, the latter only to be seen from the outside, must be assigned to about the middle of the fourteenth century. About this time, Lincoln received a treasurer, who has left abiding traces in the minster. John de Welburne has already been mentioned as having restored the precious shrine of St. Hugh. Perhaps the greatest of his benefactions are the present magnificent choir-stalls, the finest examples in the kingdom. He also constructed the vaulting of the central and western towers, and placed over the great west door the respectable row of royal statues. Welburne died in the year 1380; this we learn from a volume relating to his chantry and other foundations, written in 1382. The tracery of the three west windows has been assigned by some to him, and by others to a bishop who lived more than half-a-century later. They may be considered as belonging to the end of the fourteenth century, and mark the entrance into the next stage of Gothic architecture, the Perpendicular. The two western towers, St. Mary's and St. Hugh's, had been awaiting their completion for many years. They were now raised to a height of nearly 200 feet, by the addition of early Perpendicular storeys,
