It must be said at the outset that today reconstruction remains a sad necessity which can be applied only in certain cases, but not as a permanent element of conservation. The simplest differentiation of the supplementation of gaps is to describe lesser tasks as partial restoration and larger ones as reconstruction. The intention of conservation supplementation should be primarily to make the given object more legible, and not to restore its original appearance (a task which it is impossible to achieve anyway). Supplementation should mask gaps sufficiently to create the illusion of a uniform work, and to make it feasible to decipher its artistic merits. The opponents of such operations claim that supplementation must not be applied since a work of art should, as a document, remain in the state in which it has survived. The limits and manner of reconstruction, and even the purposefulness of supplementation, are controversial. The principles of conduct are to a considerable measure defined by the type of artwork, its value, the nature of the devastation, the legibility of the gaps, and the function of the object itself. It is necessary, therefore, to treat each work of art on an individual basis. Rigorous and strict rules cannot be observed in reconstruction owing to the unique and individual nature of every object. This means that the supplementation of gaps and reconstruction are not chosen without complete justification. They also cannot be performed according to the individual creative conceptions cherished by the conservator. General principles, applicable to all mobile monuments, recommend the treatment of the artwork as a document, and its reconstruction only in highly justified situations, without falsification of the original, and as reversibly as possible, without inflicting harm upon the monument.
