A scarce book containing the English version of French architect, Viollet-le-Duc's 'Restauration' article, translated by Benjamin Bucknall from 'Dictionnaire Raisonne de l'Architecture Francaise' in which he proposed that 'To restore a building is not to preserve it, to repair, or rebuild it; it is to reinstate it in a condition of completeness which could never have existed at any given time'. Wethered's work followed his visit to various French buildings, including Notre-Dame, the Abbey Church of St. Denis and the Chateau of Pierrefonds, to study Viollet-le-Duc's restorations. He was obviously impressed - 'Individually Viollet-le-Duc is an intellectual king among men, with personal attractions of dignity and grace befitting a descendent of the old noblesse. I have never seen a noble head or a countenance more expressive of mental power. He comprises in himself the seriousness and solidity of the English character with the verve and esprit of the French temperament.'
