Reconstructing the Dent du Requin
Viollet-le-Duc’s orthographic drawing of the Dent du Requin demonstrates the geometric order that he found underlying geology. However, the limits of this geometric rationalisation become evident in the incongruous relationship between the peak and the rhombohedral prism in his drawing of the Dent du Requin.
As drawn, the Dent du Requin appears perfectly circumscribed by the form of the rhombohedron, when in fact, this apparent coherence is only possible by means of visual trickery in a convincingly drawn projection. The misalignment between the peaks and idealised prism becomes clear through the process of reconstructing the architect’s drawing as both drawing and model.
