Jean Gimpel, in The Medieval Machine (the English translation of La Revolution Industrielle du Moyen Age), points out that the Chinese and Muslims used only human and animal force. Gimpel goes on to say : "This is convincing evidence of how technologically minded the Europeans of that era were. Paper had traveled nearly halfway around the world, but no culture or civilization on its route had tried to mechanize its manufacture."'
