Modello

Oil sketch modello by Tiepolo, 69 x 55 cm, for this five-metre-high (16 ft) altarpiece

A modello [moˈdɛllo] (plural modelli), from Italian, is a preparatory study or model, usually at a smaller scale, for a work of art or architecture, especially one produced for the approval of the commissioning patron. The term gained currency in art circles in Tuscany in the fourteenth century. Modern definitions in reference works vary somewhat. Alternative and overlapping terms are "oil sketch" (schizzo) and cartoon for paintings, tapestry, or stained glass; maquette, plastico or bozzetto for sculpture or architecture; and architectural model.
