Islamic art in museums
A more serious omission is the obscuring of the fact that some of the art actually displayed is not of Muslim origin but is at best "Islamicate," being made by Christian and Jewish craftspeople. As everyone knows, or should know, the Jews have been expelled from the Arab Islamic countries, with the Christians now following them in the current program of ethnic cleansing.
While figural arts were not forbidden by Islam (except in mosques and other sacred spaces) artists were assigned a low status. Hence the task fell largely to people of other heritages - just as wine, for example continued to be made and sold by Christians. Moreover, it is not always realized that there was a vibrant Jewish art tradition that flourished in figural mosaics and frescoes executed in synagogues right up to the time of the Islamic conquest.
