Although the mode may be readily paralleled in other North European countries, the _Rundbogenstil_ is peculiarly German. It was, indeed, the favourite mode of the thirties and forties in most German states; certainly it is comparable in local importance to the mature Gothic Revival of these decades in England as the German Neo-Gothic is not (see Chapter 6). Deriving from the more utilitarian arcuated models provided by Durand (and ultimately from the projects of his master Boullée and other French architects of the 1780s), the _Rundbogenstil_ is still a phase of Romantic Classicism even if in it the Romantic element has risen close to dominance. But in its rigidity of composition, repetition of identical elements, and emphasis on direct structural expression it is wholly in the line of the earlier and more Classical rationalism. The changing taste of these decades usually demanded ever more and busier detail. Rivalry with the archaeological pretensions of the Greek Revival, moreover, called for a certain parade of stylistic erudition. But the archaeological sources drawn upon were very various and to varying degrees effectively documented. From the Early Christian to the _quattrocento_, most of them were more or less Italianate. However, there were some architects who succeeded—like Gärtner at the Wittelsbach Palace—in using pointed-arched precedent in a characteristically _Rundbogenstil_ way; others elaborated their detail with real originality rather than adhering closely to any past precedent at all. On its _quattrocento_ side the _Rundbogenstil_ was perhaps most notably represented in Germany by the Johanneum in Hamburg of 1836-9 (completely destroyed in the Second World War), a large building surrounding three sides of a court and incorporating two schools and a library (Plate 11B). This was by C. L. Wimmel (1786-1845), like Hübsch a pupil of Weinbrenner, and F. G. J. Forsmann (1795-1878). This particular _Rundbogenstil_ work can also be classified as belonging, like Klenze’s Königsbau, to the international Renaissance Revival of which Hamburg was rather a centre. For example, the extant Exchange there of 1836-41 by these same architects is of richer and more High Renaissance character and not at all _Rundbogenstil_.
