capitals, on a line with the base of the clerestory. This
upper story has, in each bay of the vaulting, simple lancet windows
grouped in threes. The arches here, as in almost every instance
throughout the building, are supported by Purbeck marble shafts. The
nave aisles are lighted by double lancet-windows in each bay. The most
noticeable feature of these aisles is the stone bench which extends
the whole length of the building on both the north and south sides.

The west wall is panelled in three main arches, with an upper story
reaching to the height of the triforium base, and containing an arcade
of four arches, subdivided each into two smaller trefoiled ones, with
cinquefoil heads. Above these is the triplet lancet of the great west
window. The effect of the nave looking west is clearly shown in the
photograph here reproduced.

Of the chapels and altars once existing we have records in various
documents. In the "Sarum Processional" twelve altars are mentioned,
dedicated respectively to SS. Andrew, Nicholas, John the Baptist,
Margaret, Mary Magdalene, Laurence, Michael, Martin, Catherine,
Edward, Edmund the King, and Edmund, Archbishop of Canterbury. The
sites of these so far as they can be traced appears to have been: St.
Catherine and St. Martin in the north choir transept, St. Nicholas and
St. Mary Magdalene in the south, and St. Edmund of Canterbury and St.
Margaret respectively in the north and south great transepts.

Throughout the nave it is evident that the first plans were rigidly
obeyed, although the severity of the early years of the style had
become much modified before the work was finished. The absence of
ornate decoration, the simplicity of the mouldings, and the
plate-tracery of the triforium all indicate the first period of "Early
English."

The dimensions of the nave are: 229 feet 6 inches long, 82 feet wide,
and 81 feet high. The aisles are 17 feet 6 inches wide, and 39 feet 9
inches high.

=The Nave Transepts= are in three stories, with eastern aisles
divided into three bays. The screens inclosing chapels in these were
demolished by Wyatt. Above the entrances to the great transepts are
arches inserted by Bishop Beauchamp (1450-1481) to withstand the side
thrust of the great tower. These are of perpendicular work, with their
spandrils panelled and their cornices battlemented, as shown in the
engraving. Canterbury and Wells
