he south a cloister added
in 1376; and at the end of the north transept a chapel built at the end
of the fifteenth century and entered by a large archway well carved with
rich early renaissance ornament. If there is no advance from the
romanesque plan of older churches, there is none in construction. All
the arches are pointed, but that is the only direction in which any
change has been made. The piers are all cross-shaped with a large
half-shaft on each of the four main faces and a smaller round shaft in
each angle. The capitals have square moulded abaci, and are rather
rudely carved with budlike curled leaves; the pointed arches of the
arcade are well moulded, and above them runs a continuous triforium
gallery like that in the nave at Lisbon, but with small pointed arches.
The main vault is a pointed barrel with bold ribs; it is held up by a
half-barrel over the aisles, which have groined vaults with very large
transverse arches. The galleries over the aisles are lit by small
pointed windows of two lights with a cusped circle between, but except
in the lantern which has similar windows, in the transept ends and the
west front, these are the only original openings which survive. (Fig.
20.) Both transepts have large rose windows, the northern filled with
tracery, like that, common in Champagne, radiating towards and not from
the centre. The southern is more interesting. The whole, well moulded,
is enclosed in a curious square framing. In the centre a doubly cusped
circle is surrounded by twelve radiating openings, whose trefoiled heads
abut against twelve other broad trefoils, which are rather curiously run
into the mouldings of the containing circle. Over the west porch is a
curious eight-light window. There are four equal two-light openings
below; on the two in the centre rests a large plain circle, and the
space between it and the enclosing arch is very clumsily filled by a rib
which, springing from the apex of either light, runs concentrically with
the enclosing arch till it meets the larger circle. The whole building
is surmounted by brick battlements, everything else being of granite,
resting on a good trefoil corbel table, and, as the roofs are perfectly
flat, there are no gables.

The two western towers are very picturesque. The northern, without
buttresses, has its several windows arranged without any regard to
symmetry, and finishes in a round spire covered with green and white
glazed tiles. In the southern pl
