The iconography of its figures is very similar to that on the Palmer Cup, in the design of their robes, in the headgear (sharbūsh) and in the way that walking figures are rendered, with one leg straight and the other slightly bent, with a slim foot slightly raised from the ground. Although the candlestick does not have a date, it is securely datable to the early 13th century, as it clearly belongs to a group of metalwork that has now been established as of that period and coming from the Mosul or North Jaziran area. These elements also confirm the early 13th-century date of the Palmer Cup and further support the region of provenance.
