A. They are very plain, and consist of a single sweep or soffit only, without any sub-arch, as in the Norman style; and they spring from square piers; with a plain abacus impost on each intervening, which impost has sometimes the under edge chamfered, and sometimes left quite plain. Arches of this description occur at Brixworth Church, between the nave and chancel of Clapham Church, and between the nave and chancel of Wyckham Church. The arches in St. Michael’s Church, St. Alban’s, which divide the nave from the aisles, have their edges slightly chamfered. There are also arches with single soffits, which have over them a kind of hood, similar to that over doorways of square-edged rib-work, projecting a few inches from the face of the wall, carried round the arch, and either dying into the impost or continued straight down to the ground. The chancel arch of Worth Church, and arches in the churches of Brigstock and Barnack, and of St. Benedict, Cambridge, and the chancel arch, Barrow Church, Salop, are of this description. Some arches have round or semicylindrical mouldings rudely worked on the face, as in the chancel arch, Wittering Church; or under or attached to the soffit, as at the churches of Sompting and St. Botulph, Sussex. Rudely sculptured impost blocks also sometimes occur, as at Sompting and at St. Botulph; and animals sculptured in low relief appear at the springing of the hood over the arch in the tower of St. Benedict’s Church, Cambridge.

How are some of the doorways, windows, arched recesses, and panels of Anglo-Saxon architecture constructed? [Illustration: Doorway in the Tower of Brigstock Church.] A. In a very rude manner, of two or more long blocks of stone, placed slantingly or inclined one towards the other, thus forming a straight line, or triangular-headed arch; the lower ends of these sometimes rest on plain projecting imposts, which surmount other blocks composing the jambs. We find a doorway of this description on the west side of the tower of Brigstock Church, forming the entrance into the curious circular-shaped turret attached and designed for a staircase to the belfry; an arched recess of this description occurs in the tower of Barnack Church, and a panel on the exterior of the same tower, and in windows in the tower of the old church, Barton-upon-Humber, and in the tower of Sompting Church, and St. Michael’s Church, Oxford. The arch thus shaped is not, however, peculiar to the Anglo-Saxon style, but may occasionally be traced in most if not all of the subsequent styles, but not of such rude or plain construction.
