shafts. The semicircular-headed single-light window of
this style may be distinguished from those of the Norman style by the
double splay of the jambs, the spaces between which spread or increase in
width outwardly as well as inwardly, the narrowest part of the window
being placed on the centre of the thickness of the wall; whereas the jambs
of windows in the Norman style have only a single splay, and the narrowest
part of the window is set even with the external face of the wall, or
nearly so. Single-light windows splayed externally occur in the west
walls of the towers of Wyckham Church, Berks, and of Stowe Church,
Northamptonshire, Caversfield Church, Oxfordshire, and on the north side
of the chancel of Clapham Church, Bedfordshire; but windows without a
splay occur in the tower of Lavendon Church, Buckinghamshire. Small square
or oblong-shaped apertures are sometimes met with, as in the tower of St.
Benedict's Church, Cambridge; and also triangular-headed windows, which,
with doorways of the same form, will be presently noticed.

Q. Of what description are the arches which separate the nave from the
chancel and aisles, and sustain the clerestory walls?

[Illustration: Anglo-Saxon Arches, St. Michael's Church, St. Alban's, A. D.
948.]

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
