A good view of the Nave may be obtained as it is unobstructed through its whole length. A band of treble billet moulding runs under the lower windows; a double hatched moulding under the second tier; and immediately below the parapet is the ornament called the corbel table; these with the billet moulding round the clerestory windows, are in excellent preservation. The parapet on the wall of the aisle is embattled, that above the clerestory windows is plain. Although at one time battlements ran the whole length on both sides, those on the north were removed nearly one hundred years ago. The windows in the clerestory retain their original form, but those of the two lower tiers have been altered. Over one of the lower windows there appears a date (1662), probably referring to the period of some important repairs or alterations on this side. The removal of the ruins of the old Church of St. Cross, which stood near this spot, took place in the reign of Elizabeth, when the use of the Lady Chapel was granted to the parish of Holy Trinity. We next turn our attention to the Octagon, which forms a grand central point from which radiate the four principal parts of the church--the Nave, the Choir, and the north and south arms of the Transept. Here originally stood a large square Norman Tower, which fell down in 1322, and was replaced by the present building; it is not an exact octagon, having four longer sides adjoining the four main portions of the building, and four shorter sides at the angles. The design was a grand one, but whether it was ever fully carried out is somewhat doubtful, the stone-work is carried up to a height a little above the roof of the Nave, &c., but the Lantern above is of English oak covered with lead. From a strong buttress, surmounted by a pinnacle, at each of the angles formed by the walls of the Nave and Choir aisles with those of the Transept spring two massive flying buttresses, abutting octagonal turrets at each angle of the Octagon; these turrets were probably originally designed to be finished with pinnacles, and thus form a corona; between them runs a pierced parapet formerly surmounted by a bold cresting of leaves and other ornaments; and there are bases of pillars at the cardinal points. These pinnacles with the cresting have just been completed in Clipsham stone, by Mr. Wood, of Ely, in a manner highly creditable to his skill, and greatly to the improvement of the appearance of the building. Beneath the parapet, instead of a corbel table, there is a deep hollow, with running leaves, and small ball flowers at intervals. The sides of the Octagon are adorned with an arcade of pointed arches, some of which are pierced and glazed to admit light; the longer sides have six, and the shorter three, of these arches. In each of the turrets is a winding stair communicating respectively with the main parts of the building. The Lantern above is of two stories, the lower, (which is open to the interior of the
