The existence of this extraordinary edifice in a minor European capital prepares one a little for the important part that Brussels was to play in the nineties, even though there could hardly be two architects further apart in spirit than Poelaert and Victor Horta, who initiated there the Art Nouveau (see Chapter 16). So also in Glasgow, the originality of Thomson’s Queen’s Park Church of the sixties at least opened the way for the notable international contribution to be made by the Glaswegian C. R. Mackintosh in the nineties. But it was Alphonse Balat (1818-95), not Poelaert, who was Horta’s master and also in these decades professor of architecture at the local Academy. Balat’s Musée Royale des Beaux Arts of 1875-81 already represents a reversion to a more restrained and academic classicism with none of Poelaert’s force and vitality. Yet this building is not without a certain correct elegance of detail and conventional skill in composition for which his houses of the sixties, with their Barry-like handling of the High Renaissance _palazzo_ theme, prepared the way. The real eclecticism of this period lies less significantly in the variety of nominal styles employed than in the variety of ways of employing them. It is this, rather than the concurrent multiplication of fashionable modes, that makes it so difficult to characterize broadly the production of the period between the mid century and the nineties. In several other European countries the situation was made even more complicated than in Belgium by a very considerable cultural lag such as has already been noted in Scandinavia. While the Rütschi-Bleuler House in Zurich of 1869-70 by Theodor Geiger (1832-82) had the fashionable Second Empire mansard, here high and concave, at nearby Winterthur Semper’s Town Hall of precisely the same date, with its dominating temple portico, might at first sight be taken for a provincial French public edifice of the second quarter of the century. At the Zurich Polytechnic School, where Semper became a professor in 1855,[211] the large building begun in 1859 that he erected with the local architect Wolff is equally retardataire in style. His Observatory there of 1861-4 is a delicate and rather picturesquely composed exercise in the _quattrocento_ version of the _Rundbogenstil_, rather like his Hamburg houses of twenty years earlier.
