Les terrasses du donjon de Chambord: un projet de Léonard de Vinci ?

Résumé De En Fr

Die Terrassen des Donjons von Chambord - ein Projekt von Leonardo da Vinci ?, von Patrick Ponsot Die Aussicht von den Terrassen von Chambord ist unvergleichlich. Ganz so, wie die Schwierigkeit, sie abzudichten. Die Restaurierungsarbeiten haben zu drei Enrdeckungen geführt. Die kassettierten Gewölbe, die die Terrassen tragen, sind Flachtonnengewolbe ans Keilsteinen, was bis dahin in Frankreich beispiellos ist. Die Pflasterung der Terrasse wurde ursprünglich von grossen, von den Gewölben unabhangigen scheitrechten Bogen getragen. Unter der Terrasse schließlich waren bis zu den drastischen Umbaumafinahmen des 17. Jahrhunderts die Gewölbe mit glasierten tegulae ummantelt. Muss man nicht in diesen konnerschaftlichen Lösungen der Renaissance ein Echo der unermüdlichen Forschungen des Leonardo da Vinci sehen, den man heute als den Urheber des Entwurfes von Chambord ansieht ? Einige Zeichen in seiner Laufbahn und seinen Skizzenbüchern legen diesen Vorschlag nahe, trotz des Abstandes von 18 Jahren, der den Tod des großen Florentiners von den Arbeiten an den Terrassen trennt.

Were the terraces ofthe keep at Chambord designed by Leonardo da Vinci ?, by Patrick Ponsot The view from the terraces at Chambord is as incomparable as the difficulty in keeping them water-tight. Restoration work has led to three discoveries. The coffered vaults that carry the terraces are keyed barrel vaults, which hâve no comparison in France at that date. The pavement ofthe terrace was originally laid on large keyed beds that were independent from the vaults. Finally, under the terrace, before the drastic reconstruction in the seventeenth century, the vaults were covered with a mantle of varnished tegulae. Shouldn't these skilful Renaissance solutions be seen as an écho ofthe insatiable expérimentation of Leonardo da Vinci, whom we recognize today as the designer of Chambord ? Certain points of référence noted in his work and in his Carnets suggest the possibility, despite the eighteen years that separate the death of the great Florentine artist and the work on the terraces.
