1750 and 1790 the new style that is called ‘Romantic Classicism’[1] took form, producing by the eighties its most remarkable projects, and even before that some executed work of consequence in France and in England. Thus the nineteenth century could inherit the tradition of a completed architectural revolution, and at its very outset was in possession of a style that had been fully mature for more than a decade. The most effective reaction against the Baroque in the second, and even to some extent the third, quarter of the eighteenth century had taken place in England; the later architectural revolution that actually initiated Romantic Classicism centred in France. Yet Paris was not the original locus of the new style’s gestation but rather Rome.[2] From the early sixteenth century Rome had provided the international headquarters from which new ideas in the arts, by no means necessarily originated there, were distributed to the Western world. To Rome came generation after generation of young artists, connoisseurs, and collectors to form their taste and to formulate their aesthetic ideals. Some even settled there for life. From the time of Colbert the French State maintained an academic establishment in Rome for the post-graduate training of artists. Thus French hegemony in the arts of the late seventeenth and early eighteenth centuries was based on a tradition maintained and renewed at Rome. The nationals of other countries came to Rome more informally, and were for the most part supported by their own funds or by private patrons; only in the seventies were young English architects of promise first awarded travelling studentships by George III. In the fifties the number of northern architects studying in Rome notably increased; some of them, beginning with the Scot Robert Mylne (1734-1811) in 1758, won prizes in the competitions held by the Roman Academy of St Luke.[3]
