+THE CLASSIC REVIVAL.+ The influence of the classic revivals of Europe began to appear before the close of this period, and reached its culmination about 1830-40. It left its impress most strongly on our Federal architecture, although it invaded domestic architecture, producing countless imitations, in brick and wooden houses, of Grecian colonnades and porticos. One of its first-fruits was the White House, or Executive Mansion, at Washington, by _Hoban_ (1792), recalling the large English country houses of the time. The +Treasury+ and +Patent Office+ buildings at Washington, the Philadelphia Mint, the +Sub-treasury+ and +Custom House+ at New York (the latter erected originally for a bank; Fig. 221), and the +Boston Custom House+ are among the important Federal buildings of this period. Several State capitols were also erected under the same influence; and the Marine Exchange and +Girard College+ at Philadelphia should also be mentioned as conspicuous examples of the pseudo-Greek style. The last-named building is a Corinthian dormitory, its tiers of small windows contrasting strangely with its white marble columns. These classic buildings were solidly and carefully constructed, but lacked the grace, cheerfulness, and appropriateness of earlier buildings. The Capitol at Washington was during this period greatly enlarged by terminal wings with fine Corinthian porticos, of Roman rather than Greek design. The +Dome+, by _Walters_, was not added until 1858-73; it is a successful and harmonious composition, nobly completing the building. Unfortunately, it is an afterthought, built of iron painted to simulate marble, the substructure being inadequate to support a dome of masonry. The Italian or Roman style which it exemplified, in time superseded the less tractable Greek style.
