A very elegant pointed arch, now forming the entrance from the tower to the interior of the church, of which we have given a representation on a preceding page, appears to be of the reign of Henry III.; the defects observed in the upper part of its ornaments were caused by some barbarous hand, which cut away part of the sculptured stone, in order to introduce a new erection, with which the workman appears to have proceeded no farther. The <g>Principal Entrance</g>, which is also an elegant sharply-pointed arch, is supposed to date from the reign of Edward III. At the south-east extremity of the present building is a chapel, which bears evident marks of the age of the Tudors, although much defaced and altered. Nearly the whole of the church itself, with the exception of the modern alterations which it has undergone, is the erection of King Harold, and formed perhaps the principal part of the church as he left it. The interior, which in modern times has been miserably disfigured by thick coats of plaster and whitewash, possesses still an appearance of solemn grandeur, although its groined roof has been taken down, and its place supplied by a lower flat ceiling. The close resemblance between this interior and the interior of the nave of Durham Cathedral (built a few years after the Conquest) has frequently been noticed. The body of the nave is separated from the side aisles by two rows of large and massive cylindrical pillars, ornamented with spiral and zig-zag grooves, like the similar pillars in the nave at Durham. These pillars support large circular arches, with zig-zag mouldings. Above these on each side is a second row of large arches, supported by short columns; and above these is a third series of treble arches, each consisting of one large arch, with a smaller one on each side. These latter front the principal windows by which the interior of the church is lighted. In the second or middle tier of arches there were once central columns, with arched mouldings, dividing each of the large arches into two. Between each series of arches a three-quarter pilaster moulding rises to the ceiling, and appears formerly to have sustained the groined roof. Two of the circular arches of the lower row have been altered, probably at the time [Illustration] when the present steeple was erected, to pointed arches, and carried up to the string course of the clerestory. The only remnant of the furniture and utensils of this old church is its ancient <g>Font</g>. The east end of the nave has been railed in to form a chancel. The whole length of the nave is a hundred and six feet; and its breadth fifty-three feet, including the aisles. The interior height is at present forty-six feet. The most interesting monument in Waltham Abbey Church is that of Sir Edward Denny and his lady, which is situated near the eastern extremity of the south aisle. Near the altar rails is a defaced grey slab, which once bore a mitred figure, probably one of the abbots.
