Classical Order - Nonce Orders

Nonce Orders

Several orders, usually based upon the composite order and only varying in the design of the capitals, have been invented under the inspiration of specific occasions, but have not been used again. Thus they may be termed "nonce orders" on the analogy of nonce words. Robert Adam's brother James was in Rome in 1762, drawing antiquities under the direction of Clérisseau; he invented a British Order, of which his ink-and-wash rendering with red highlighting, is at the Avery Library, Columbia University. Adam published an engraving of it. In its capital the heraldic lion and unicorn take the place of the Composite's volutes, a Byzantine/Romanesque conception, but expressed in terms of neoclassical realism. In 1789 George Dance invented an Ammonite Order, a variant of Ionic substituting volutes in the form of fossil ammonites for John Boydell's Shakespeare Gallery in Pall Mall, London.

In the United States Benjamin Latrobe, the architect of the Capitol building in Washington DC, designed a series of botanically American orders. Most famous is the order substituting corncobs and their husks, which was executed by Giuseppe Franzoni and employed in the small domed Vestibule of the Supreme Court. Only the Supreme Court survived the fire of August 24, 1814, nearly intact. With peace restored, Latrobe designed an American order that substituted for the acanthus tobacco leaves, of which he sent a sketch to Thomas Jefferson in a letter, November 5, 1816. He was encouraged to send a model of it, which remains at Monticello. In the 1830s Alexander Jackson Davis admired it enough to make a drawing of it. In 1809 Latrobe invented a second American order, employing magnolia flowers constrained within the profile of classical mouldings, as his drawing demonstrates. It was intended for "the Upper Columns in the Gallery of the Entrance of the Chamber of the Senate" (United States Capitol exhibit).

These nonce orders all express the "speaking architecture" (architecture parlante) that was taught in the Paris courses, most explicitly by Étienne-Louis Boullée, in which sculptural details of classical architecture could be enlisted to speak symbolically, the better to express the purpose of the structure and enrich its visual meaning with specific appropriateness. This idea was taken up strongly in the training of Beaux-Arts architecture, ca 1875-1915: see architecture parlante.
