A model-independent approach in which the sculptor works the stone without transferring a full-scale model through a formal pointing system.
Scultura libera is the term used by Le voci del marmo in contrast with sculpture executed from a 1:1 model. It describes carving that is not governed by systematic point transfer from a full-size model.
Etymology
Italian: scultura, “sculpture,” + libera, “free.”
Sculptor Notes
Scultura libera should not be confused with lack of planning. A sculptor may work from drawings, a small bozzetto, measurements, anatomical knowledge, or direct judgment while still allowing decisions to emerge within the stone itself.
