VII. PERPENDICULAR (1360-1485).—In 1458 the southern and eastern sides of the central tower collapsed, greatly damaging the adjacent parts of the choir and transept, as well as the stalls. The eastern aisle of the south transept and much of the south side of the choir, as well as part of the tower, had to be rebuilt; and about 1490 the present choir-stalls were put up. In the choir the builders, with a conservatism which does them credit, both in the work of 1280 and in that of 1458, preserved all they could of the twelfth-century work, and both in the Geometrical and the Perpendicular bays of the triforium retained the semicircular arch of the older design. The result is a curious blend of styles. Starting from the east, the first pier on the north side is Geometrical, the rest Transitional. On the south side the first pier is Geometrical, the second Transitional, the third and fourth Perpendicular. To give more support to the tower, the north-east and south-west piers were cased; the south-east pier was rebuilt, and the southern and eastern arches were rebuilt. To strengthen the eastern piers of the tower, the two western bays of the arcade of the choir were blocked up, and a massive choir-screen was inserted _c._ 1480.

TUDOR.—Early in the sixteenth century the canons unhappily determined to give their unique church more of the look of a cathedral by adding aisles to the nave. It is pleasant to add that they were unsuccessful. The nave is exceedingly low in proportion to its exceptional span, and being, moreover, unprovided with a triforium, does not look in the least like a cathedral, but like a very inferior parish church. Externally, the buttresses are of fine composition, and if the pinnacles were completed, the nave would be very handsome externally. In 1593 the central spire—of timber and lead—was struck by lightning, and in 1660 it was removed. It was 120 feet high. In 1664, for fear of a similar catastrophe, the western spires also were removed. The result is that, seen from a distance, _minus_ spires and _minus_ pinnacles, Ripon Minster is stunted and squat.
