This is the right leaf on an ivory diptych, made in France, probably Paris, in about 1340-1350. Ivory was used all over Europe for religious works of art. It was often combined with precious metals and usually took the form of relief panels, for book covers, portable altars and caskets. An almost unbroken tradition of ivory carving extends from the Roman and Byzantine empires until the end of the 14th century. From about 1250, Paris became the centre of production for figures and reliefs intended for private devotion. Other workshops emerged in Italy and Germany. Venice was one of the centres of ivory carving in Italy.
Ivory plaques such as this were normally arranged in diptychs or triptychs. Diptychs consisted of two tablets hinged together, while triptychs were two tablets hinged on either side of a central tablet. The smaller ones were probably held in the hand and opened like a small book, while the larger ones would have stood open on a table or altar.

The devotional diptych is in many ways the object type most associated with the notion of Gothic ivory carving. The earliest examples probably date to the 1240s; these are complex, large and ambitious works that emerged, somewhat surprisingly, with no obvious precursors. The owners of ivory diptychs sometimes appear within their images. Such portraits indicate that they were special requests on the part of their commissioners, and they parallel the similar figures that appear in manuscripts and panel paintings of the period. The iconography of Gothic diptychs oscillated between two poles. The first of which is the desire to present narratives (Life of Christ and Virgin Mary) for envisaging. The second was the use of non-narrative images to form the focus of devotion.
