Soufflot’s vast cruciform Panthéon provides no such simple paradigm as Stuart’s temple. No longer really Baroque, it is by no means thoroughly Romantic Classical. Like most of the work of the leading British architect of Soufflot’s generation, Robert Adam (1728-92),[8] the Panthéon must rather be considered stylistically transitional. For example, the purity of the temple portico at the front, in any case Roman not Grecian, is diminished by the breaks at its corners. The tall, hemispherical dome[9] over the crossing is even less antique in character, owing its form to Wren’s St Paul’s rather than to the Roman Pantheon, which was the favourite domical model for later Romantic Classicists. In the interior, up to the entablatures, the columniation is Classical enough and the structure entirely trabeated[10]—at least in appearance (Plate 1). Above, the domes in the four arms are perhaps Roman, but hardly the pendentives that carry them; these are, of course, a Byzantine structural device revived in the fifteenth century by Brunelleschi. Over the aisles the cutting away of the masonry and the general statical approach, while not producing anything that _looks_ very Gothic, illustrate the results of Soufflot’s long-pursued study of Gothic vaulting. Many aspects of nineteenth-century architectural development were thus presaged by Soufflot here, as will become very evident later (see Chapters 1-3, 6, and 7).[11] The Panthéon was finally finished in the decade after Soufflot’s death by his own pupil Maximilien Brébion (1716-_c._ 1792), J.-B. Rondelet (1743-1829), a pupil of J.-F. Blondel, and Soufflot’s nephew (François, ?-_c._ 1802). Well before that, a whole generation of French architects had developed a mode, similar to Adam’s in England, which is usually called, despite its initiation long before Louis XV’s death in 1774, the _style Louis XVI_. Whether or not this mode in its inception owed much to English inspiration is still controversial. In any case it was widely influential outside France from the seventies to the nineties, and in those decades both French-born and French-trained designers were in great demand all over Europe, except in England; and even in England French craftsmen were employed. With that completely eighteenth-century phase of architectural history this book cannot deal, even though most of the architects who after 1800 had first made their reputation under Louis XVI, or even earlier under Louis XV. The _style Louis XVI_ and the English ‘Adam Style’ were over, except in remote provinces and colonial dependencies, by 1800.
