This book written by a German and appeared in the 60s in Germany still seems to me to be especially topical events today ... I recommend it strongly to get an idea of the level of wealth and culture (in all literary, scientific, geographic, astro-physics, ...) of the Arab-Muslim civilization in order to reduce Amalgammes today. The book also talks about the legacy left by this civilization in the Western world and in our lives every day. To read at all costs !!!!
