er's at Rome,
which exercised such an influence over Wren. This immense building
has, in the exterior, only one Order and an Attic. All three have the
round arch.

[70] Fergusson, "Modern Architecture," p. 390.

[71] An _Attic_ is a small story above the cornice, or principal
elevation of a building. [The same would read better by substituting
"story" for "elevation".] An _Attic order_ is an inferior order of
architecture, used over the principal order of a building. It never
has columns, but, sometimes, small pilasters. (Longman, note, p. 164.)
Very common in Roman and Italian, but unknown in Greek.

[72] "At St. Paul's the Surveyor was cautious not to exceed Columns of
four Feet, which had been tried by _Inigo Jones_ in his Portico; the
Quarries of the Isle of _Portland_ would just afford for that
proportion, but not readily for the Artificers were forced sometimes to
stay some Months for one necessary Stone to be raised for their
Purpose, and the farther the Quarry-men pierced into the Rock, the
Quarry produced less Stone than near the Sea. All the most eminent
Masons were of Opinion, that Stones of the largest Scantlings were
there to be found, or nowhere. An Enquiry was made after all the good
Stone that England afforded. Next to _Portland_, _Rock-abbey_ Stone,
and some others in Yorkshire seemed the best and most durable; but
large Stone for the _Paul's_ Works was not easily to be had even there.
For these Reasons the _Surveyor_ concluded upon _Portland-stone_, and
also to use two Orders, and by that Means to keep the just Proportions
of his Cornices; otherwise he must have fallen short of the Height of
the Fabrick.... At the _Vatican Church_ [St. Peter's], Bramante was
ambitious to exceed the ancient _Greek_ and _Roman_ Temples ... and
although by Necessity he failed in the due Proportions of the proper
Members of his Cornice, because the _Tivoli_ stone would not hold out
for the Purpose; yet (as far as we can find) he succeeded in the
Diameter of his Columns, viz., nine Feet."--_Parentalia_, p. 288.

[75] Tracts in "Parentalia," pp. 352-353. Stephen Wren (p. 269)
explains how his grandfather departed from the conventional
arrangement of architrave, frieze, and cornice in his entablatures,
omitting one or other of these whenever he thought good. Here, above
