What happened to him anyways? FLG is still very big and in the news but their godman isn't.
The globe in the fake painting depicts parts of the Earth that were not known to medieval Arabs during the so-called Islamic Golden Age. During the time of Galileo, the main technologically advanced states in the Islamic world were the Ottoman and Mughal empires, both of which had extensive contact with the West, but the painting style quite obviously does not resemble that of either country. BTW I find it hard to believe that you have not heard of Muslims trumpeting how much advanced they were a thousand years ago, and extremist Muslims claiming the Quran as an basis for all STEM. or that science proves Quranic miracles.
