The brothers Gaspard (born 1624 or 1625, died 10 December 1681) and Balthazar Marsy (baptised 6 January 1628, died May 1674) were French sculptors. Originally from Cambrai, they moved to Paris and were employed by King Louis XIV, particularly for the decoration of the palace and gardens at Versailles.
Their sister Jeanne was married to the sculptor Pierre Le Gros the Elder and was the mother of the sculptor Pierre Le Gros the Younger.
Stucco or render is a construction material made of aggregates, a binder, and water. Stucco is applied wet and hardens to a very dense solid. It is used as a decorative coating for walls and ceilings, exterior walls, and as a sculptural and artistic material in architecture. Stucco can be applied on construction materials such as metal, expanded metal lath, concrete, cinder block, or clay brick and adobe for decorative and structural purposes.
In English, "stucco" sometimes refers to a coating for the outside of a building and "plaster" to a coating for interiors. As described below, however, the materials themselves often have little or no difference. Other European languages, notably Italian, do not have the same distinction: In Italian, stucco means plaster, and serves for both.
