 This approach was determined in part by the chronic lack of funds at the Comité's disposal, which did not allow complete restoration on a large scale.At a very early stage the Comité decided that its foremost task was to secure the survival of the greatest possible number of monuments, which children of a happier and richer age would subject to complete restoration.In Herz's practice "stylistic purity" meant that in the case of periods whose architecture was well known owing to the existence of numerous monuments, he regarded as permissible the analogical reconstruction of structures whose original shape was unknown.
