Personally, I believe that in the course of devising the past as ancient and antiquity and the Middle Ages, no will not be able to identify a single action. As always, there was chaos, which many have tried to bring some semblance of order. There was a collective creation, which involved writers followed, as far as possible, for the work of their colleagues and tried not to contradict them, at least too clearly. Of course, were interested forces and groups were the ideological inspirers and leaders who were the organizers of the mass production, was the movement of funds, but to an even greater extent than the ringing of filthy lucre than greed and legitimate search for material success, the writers of the past have moved the desire for fame, but and other motives. At least in the last century, religious, ideological, in particular nationalist or misconceived patriotism played a lesser role than the hope of getting at least some of the fee.
