John Grandisson,
bishop of Exeter from 1327 to 1369, was a man of education, culture, and capital. This example of medieval English ivory carving is unusual because it is carved with the bishop's emblems. Grandisson changed his family's coat of arms by substituting a
mitre for the normal central eaglet, making the arms unique to him. The coat of arms almost certainly means that this work of art was commissioned by Bishop Grandisson during his tenure. There is a second ivory triptych in the British Museum and two leaves divided between the British Museum and
the Louvre. They are carved with the same arms. The Grandisson ivories in the Louvre and British Museum demonstrate
iconographic features that suggest Italian influence and the style of paintings from the
province of Siena in Tuscany. Saltykov bought the artefact in Paris from Louis Fidel Debruge-Duménil. ==References==
