The embroidery is carried out in silver-gilt thread and underside couching, as an early example of opus anglicanum.
Soon after his death on 29 December 1170, Thomas Becket was honoured in England as a martyr who had died for the freedom of the Church. Depictions of his martyrdom in gold embroidery, especially mitres elaborately embroidered in gold thread (opus anglicanum), acted to propagate the cult throughout the European continent.
This mitre originates from Kloster Selingenthal, near Langshut (Bavaria). It is said to have been donated by Duchess Ludmilla of Bavaria (c. 1170-1240), and it may thus show the early spread of Thomas Becket's cult across Europe.
