I want to know the answer to the following question:
In Syria and Egypt, other than early Christians, who influenced their mosaic work?
All the background I'm provided with is that "During the Umayyad Dynasty mosaic making remained a flourishing art form in Islamic culture and it is continued in the art of zellige and azulejo in various parts of the Arab world, although tile was to become the main Islamic form of wall decoration.". Is that enough to answer the question?
