This very small picture is on the ceiling of the Cappella Palatina. It was a palace originally built for the emirs, but had been abandoned. After the Norman invasion, it was rebuilt by Roger the II, who was crowned King of Sicily there.
Unfortunately I could not find a better picture of the dancer. If you have one, please let me know. Taken from the site Dancing in Art by Betty Eyer.
