MILAN ST AMBROZIO
Vaulting. from pier to pier is as wide as the of the
pier: similar sub-arches are thrown under the Roman
vaulting across the aisle; but these are narrower
than the main arches; and are carried by the
smaller shaft of the pier on the side of the aisle,
whose semicircle a b fig 2 p 34 1 N is exactly the
breadth of sub-arch. The relations of the whole pier
to its opposite archivolt pier B are marked in fig 2
and anove in fig 1 this disposition of the vaulting
and sub-arch on main pier: the breadtns a and b
in this figure are the a and b of fig 1 opposite
when c and d are respectively the first order and
cornice shaft. By comparing the section A fig 2 - p 34 1
with the section in No 1 of the main pier, it is seen
that A. is a shaft in front of pilasters: B a pilatste r
in front of shafts: while the breadth a b of A
being still further dimishiehd to the eye by its
curvature; so as to appear almost a slender shaft,
note further the angular portions of A carry bc
the vaulting cd a narrow sub arch run on the wall
as a facing c d being in fact a edge shaft, it is no
so deep as the sub arch of B. and the whole
capital narrower therefore, as above by dotted line
The vaulting itself is so far domical or rather conical
for it is little curved, that the intersection of the
four cells is hardly perceived.
