After the fall of Rome in 476 A.D., there was an immensely long period of relatively little progress. Of course the confusion had already begun in the third century A.D., when economic hardship and political confusion was growing. History teaches us that, in such circumstances, most people have little time for abstract speculation and scientific research. Instead, as is usually the case, the people of Europe turned toward religion, to the new cults of Christianity, to Serpis, and to Mithraism. To add to this confusion, there were at least three civilizations ready to fill in the power gap caused by Rome’s fall: the Byzantine civilization, western Christianity, and the new religion of Islam.
