A method of producing a sculpture from a full-scale model, allowing dimensions and surface points to be transferred directly at the same scale.
Scultura da modello in scala 1:1 means sculpture made from a full-scale model. Le voci del marmo explicitly contrasts this model-based approach with scultura libera.
Because model and marble are the same scale, pointing systems can transfer locations without proportional enlargement or reduction.
Etymology
Italian workshop phrase: “sculpture from a model at 1:1 scale.”
Sculptor Notes
A 1:1 model can separate invention from execution: composition and anatomy may be resolved in clay or plaster before the marble is approached. The stone stage then becomes interpretation, transfer, and refinement rather than pure discovery.
