A. There are some subterranean vaults, not easily accessible, the presumed remains of Bishop Wilfrid’s work, at Ripon and Hexham, of the latter part of the seventh century; but the crypt beneath the chancel of Repton Church, Derbyshire, the walls of which are constructed of _hewn_ stone, is perhaps the most perfect specimen existing of a crypt in the Anglo-Saxon style, and of a stone vaulted roof sustained by piers, which are of singular character; the vaulting is without diagonal groins, and bears a greater similarity to Roman than to Norman vaulting. [Illustration: Crypt, Repton Church, Derbyshire.] Q. Are mouldings, or is any kind of sculptured ornament, to be met with in Anglo-Saxon work? A. Although the remains of this style are for the most part plain and devoid of ornamental detail, we occasionally meet with mouldings of a semicylindrical or roll-like form, on the face or under the soffit of an arch, and these are sometimes continued down the sides of the jambs or piers. Foliage, knot-work, and other rudely sculptured detail occur on the tower of Barnack Church, and some rude sculptures appear in St. Benedict’s Church, Cambridge; and the plain and simple cross of the Greek form, is represented in relief over a doorway at Stanton Lacey Church, and over windows in the tower of Earls Barton Church. Q. What was the general plan of the Anglo-Saxon churches? A. We have now but few instances in which the complete ground plan of an Anglo-Saxon church can be traced: that of Worth Church, Sussex, is perhaps the most perfect, as the original foundation walls do not appear to have been disturbed, although insertions of windows of later date have been made in the walls of the superstructure. This church is planned in the form of a cross, and consists of a nave with transepts, and a chancel, terminating at the east end with a semicircular apsis--a rare instance in the Anglo-Saxon style, as in general the east end of the chancel is rectangular in plan. The towers of Anglo-Saxon churches are generally placed at the west end, though sometimes, as at Wotten Wawen, they occur between the chancel and nave. No original staircase has yet been found in the interior of any. The church at Brixworth, an edifice of the seventh century, and that of St. Michael, at St. Alban’s, of the tenth century, have aisles. Sometimes the church appears to have consisted of a nave and chancel only. Q. Why have we so few ecclesiastical remains of known or presumed Anglo-Saxon architecture now existing? A. There are probably many examples of this style preserved in churches which have hitherto escaped observation[49-*]; still they are, comparatively speaking, rarely to be met with: and this may be accounted for by the recorded fact, that in the repeated incursions of the Danes in this island, during the ninth and tenth centuries, almost all the Anglo-Saxon monasteries and churches were set on fire and destroyed.
