Again, in the first bays of the aisles there are windows in the Early English style, but they look only into the aisles of the transepts; showing, as has before been stated, that the transept aisles were not originally contemplated, and certainly did not take the place of earlier Norman aisles. [Illustration: THE CHOIR, LOOKING WEST.] The arch at the west end of the north choir aisle is decorated with a double chevron moulding--evidence that it is one of the oldest pieces of work left in the cathedral. This arch has at a more recent date been lined with another arch of the Decorated period, probably in order to strengthen it. The arcading in the aisles is very interesting. In the first three western bays in both aisles the large arcading, with its plain trefoiled arches, is clearly Early English. The arcading in the other bays is equally clearly of the Decorated period, and is considerably smaller. In the four eastern bays in each aisle the arches go right up to the course which forms the top of the arcading, and the triangular spandrels thus formed are ornamented each with a curious little head, having queer headgear; the rest of the spandrel is carved with foliage, and in the plates of the foliated arches are quaint animals. The arcading in the remaining bay is similar, but angels' heads with wings take up the whole spandrel. Some of the arcading, notably that in the three easterly bays of the south aisle, is unrestored. The inferiority of the modern work in the next bay is only too patent. In the south choir aisle the third window from the east has very beautiful carved work, the splays being covered with two bands of richly-carved foliage. Under the window is now the tomb of Bishop Hacket, and Dean Heywood's monument is said to have also been in this place.
