This small ivory casket has carved decoration of stylised plants. It covers the sides of the base and the top of the lid. Around the sides of the lid there is an Arabic inscription composed in a decorative style of script known as 'floriated Kufic'. The silver hinges and hasp may well be original. They are decorated in niello. This is a technique in which the decorator uses black inlay to fill the hollow design in a metal surface.

Ivories of this kind were produced in Spain during the 10th and 11th centuries. At this time most of the country was ruled by Muslim Arabs of the Umayyad dynasty. The inscription tells us that this casket was made for the daughter of the Umayyad caliph 'Abd al-Rahman III. His name is followed by a short prayer said only for the deceased. We can therefore date the casket to the period after the caliph's death in 961.

One theory suggests that this type of decoration consisting entirely of plants, with its associations with fertility, was suitable for objects owned by women. Yet the same type of decoration appears in the carved marble wall panels of the reception hall in Madinat al-Zahra. This hall was used only by men and was part of the huge palace complex 'Abd al-Rahman built near Cordoba. Designers therefore used the same style of decoration in different media. This suggests at the very least that there was some central control in the production of all the decorative arts at this time.

This casket is probably a pair with A.580-1910, which was made at the same time for the same daughter of 'Abd al-Rahman III. The commission may have commemorated a significant event in her life, such as a marriage or birth of a son.
