Gothic sculptures independent of architectural ornament were primarily created as devotional objects for the home or intended as donations for local churches, although small reliefs in ivory, bone and wood cover both religious and secular subjects, and were for church and domestic use. Such sculptures were the work of urban artisans, and the most typical subject for three dimensional small statues is the Virgin Mary alone or with child. Paris was the main centre of ivory workshops, and exported to most of northern Europe, though Italy also had a considerable production. An exemplar of these independent sculptures is among the collections of the Abbey Church of St Denis; the silver-gilt "Virgin and Child" dates to 1339 and features Mary enveloped in a flowing cloak holding an infantile Christ figure. Both the simplicity of the cloak and the youth of the child presage other sculptures found in northern Europe dating to the 14th century and early 15th century. Such sculpture shows an evolution from an earlier stiff and elongated style, still partly Romanesque, into a spatial and naturalistic feel in the late 12th and early 13th century. Other French Gothic sculptural subjects included figures and scenes from popular literature of the time. Imagery from the poetry of the troubadours was particularly popular among artisans of mirror-cases and small boxes presumably for use by women. The Casket with Scenes of Romances (Walters 71264) of 1330–50 is an unusually large example with space for a number of scenes from different literary sources.
