Nike was the ancient Greek goddess of Victory, being sister to Zelos (zeal), Kratos (strength) and Bia (force). She was typically depicted with outstretched wings and one foot forwards, at the moment of landing on the prow of a ship. (The Samothrace Nike in the Louvre providing the most well known example). A laurel wreath is usually held aloft in one hand, ready for crowning the victor.
This model is illustrated in the catalogue J.Chiurazzi & Fils, Fournisseurs de Cours et Musées..., Milan, 1900, and appears as item number 17, Victoire. The figure is represented as lacking her right arm and fingers of her left hand, the original in the Naples Museum having been excavated in this state. A later catalogue; Fonderie Artistiche Riunite, J. Chiurazzi & Fils - S. De Angelis & Fils, number 4997, p.210, describes the model as Victoire aux ailes tendues et dont le bras droit est perdu, confirming this.
