There is no external polychromy of glass or tile here, and the frescoed colour used on the court walls has suffered such serious deterioration that it is difficult to know what it was like originally. On the other hand, Gaudí’s detail was never more carefully studied nor more consistent; there are no straight lines at all, and in the forms of the piers rising from the ground to support the balconies of the first storey he suggested natural formations with real success (Plate [135B]). These elements look as if they had been produced by the action of sea and weather rather than by the chisel, quite as does much of the mid-twentieth-century sculpture of Henry Moore.

The marine note is seen at its strongest and most naturalistic in the ironwork however. Strewn over the balcony parapets and across various openings, like seaweed over the rocks and sand of the seashore, the railings and grilles are full of intense organic vitality with none of the graceful droopiness of Guimard’s Métro entrances. Gaudí’s metalwork frequently suggests the work of various mid-twentieth-century sculptors in welded metal, quite as his handling of masonry does later sculpture in stone. Indeed, his iron grilles often exceed such sculptors’ metalwork in richness and variety of form, as also in the fine hand-craftsmanship of the execution.

The detailing on the Casa Milá, whether of the masonry or the ironwork, avoids the nightmarish overscaling of the somewhat similar elements at the Parc Güell, and also the coarseness of the broken faience mosaic surfaces that he used so much there and elsewhere but here restricted to the roof-tops. As regards the masonry, moreover, it is really wrong to speak of detailing, for the very fabric of the structure, not just its edges and its trimmings as on the Casa Batlló, has been completely moulded to the architect’s plastic will. Whether or not it be correct to consider the Casa Milá an example of the Art Nouveau—and technically it is not—La Pedrera remains one of the greatest masterpieces of the curvilinear mode of 1900, rivalled in quality only by the finest of Sullivan’s skyscrapers (Plate [119]), which it does not, of course, resemble visually at all.

Despite the esteem in which his work has always been held by his fellow-citizens of Barcelona, Gaudí had few local imitators of consequence. However, such detailing on early twentieth-century buildings there as may appear at first to be conventionally Art Nouveau is often in fact a bit Gaudian. Only his assistants Francisc Berenguer (1866-1914) and J. M. Jujol Gibert (1879-1949) seem to have understood Gaudí’s mature style. At least the house by Jujol at 335 Diagonal in Barcelona, though quite small and simple, and the Bodega Güell at Garraf of 1913 by Berenguer are of a quality worthy of comparison with Gaudí’s own best work.[[393]] The big Palau de la Musica Catalana, built by Luis Domenech Montaner (1850-1923) in 1908, is a very extravagant example of the architecture of the period, bold and coarse and rich, but with none of Gaudí’s personal flair and integrity.

In Glasgow Mackintosh after 1908 was a prophet with far less honour than ‘Greek’ Thomson had received there in an earlier day. But the countercurrent that he had helped to set going on the Continent was in full swing, particularly in Austria and in Germany (see Chapters [20] and [21]). Even in Horta’s own Brussels, Josef Hoffmann had been called from Vienna as early as 1905 to build the suburban Stoclet mansion (Plate [154A]) at 373 Avenue de Tervueren (see Chapter [21]).

Despite the ephemeral nature of much of its production and the completeness with which it was ultimately rejected everywhere, the Art Nouveau has very great historical importance. The Art Nouveau offered the first international programme for a basic renewal of architecture that the nineteenth century actually set out to realize. Most earlier programmes, moreover, even if not primarily revivalistic, aimed chiefly at the reform of architecture; this was still true of Voysey and his English contemporaries in these very years, though not, of course, of Sullivan and Wright, working in isolation in the American Middle West. Thus the Art Nouveau was actually the first stage of modern architecture in Europe, if modern architecture be understood as implying, before anything else, the total rejection of historicism.

The proto-modernity of earlier stages of nineteenth-century architectural development is almost always ambiguous, since the leaders of the various successive movements rarely intended to break with the past entirely. The characteristic ideal of nineteenth-century architects, as of their late eighteenth-century predecessors, had been to react against what they considered the decadence of the building arts current in their day by returning to the principles of some earlier and supposedly purer or more vital age. The very considerable amount of innovation that many European architects before Horta introduced in their work was not exactly unconscious; but it was rather a matter of achieving personal expression by adapting old forms to new needs, new materials, and new methods of construction than of creating a wholly original modern style.

Well before the nineties a very few men had consciously sought absolute originality and total freedom from the disciplines of the past. But such architects found little or no public support for their programmes of architectural revolution nor even fellow-artists to share in their highly individualistic campaigns. After the relatively universal acceptance of the doctrines of Romantic Classicism there had followed chiefly a succession and a multiplication of divergences; now, in the nineties, a real pattern of convergence appeared. But this convergence was premature. The renewal of ornament and of the accessories of architecture outran the renewal of the more basic elements of the art of building towards which the technical developments of the nineteenth century had been so inevitably leading.

Thus the Art Nouveau stands apart both from the architecture of the preceding hundred years and from the modern architecture of the following sixty which extends down to the present. It did not bring the one to an end, as the profusion of so-called ‘traditional’ buildings of the early twentieth century makes very evident (see Chapter [24]), nor did it provide much more than a preface to the major new developments that mark the early decades of the present century (see Chapters [18]-[21]). That the Art Nouveau was completely rejected on principle by ‘traditionalists’ is not surprising: it was the first serious attack on the position they continued to maintain. But the very rapidity with which the Art Nouveau rose to popularity and descended to vulgarization encouraged its denigration in the name of ‘taste’ by almost all other architects soon after it reached its climax around 1900. In recompense, interest in the Art Nouveau began to revive early, by the early thirties, after a much shorter period of neglect than other phases of nineteenth-century architectural development have undergone and are still undergoing.

The place of the Art Nouveau in the story of modern architecture, if only as an episode of youthful wild-oat-sowing, is now well established. Most of its exponents actually lived long enough to receive in their later years embarrassing praise for youthful work they had quite disowned if not forgotten. It is a curious paradox that although most of the leaders of the Art Nouveau survived for decades—and Van de Velde died only in 1957—not one except Gaudí[[394]] maintained after 1910 the position of relative pre-eminence that had been his in 1900. A wholly new cast of characters, many of them no younger, came to the fore in the first decade of the twentieth century; they constitute the first generation of modern architects, properly speaking.
