We had to put together as complete as possible a table of the events in the ancient and medieval history of Europe, the Mediterranean, Egypt, and the Middle East - of course, in the traditional chronology. To do this we combined the information from 15 chronological tables and 228 primary sources. Together these chronicles describe practically all important events between 4000 B.C. and 1800 A.D. In this way we constructed a table, which we call "global chronological diagram" (GCD):

\**IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII#III
** K TH T TP TC C[4]

Our statistical methods for dating events and recognizing duplicates were applied to the large quantity of historical data in the table GCD. After performing a vast computer experiment, involving the analysis of hundreds of texts, we unexpectedly discovered pairs of periods which in traditional history are assumed to be independent (in all senses of the word) but which have statistical characteristics which are extremely close.

Let us give an example. The chapter-volume graph for the primary sources which describe ancient Roman history from 753 B.C. to 236 B.C. has its local maxima at essentially "the same points" as the analogous graph for medieval Roman history from 300 A.D. to 816 A.D. Of course, here we must first align the two 500-year time intervals. This same statistical parallelism was also revealed by other methods.

Global chronological diagram represents modern version of traditional "textbook" of ancient and medieval history and chronology (based on Scaliger's chronology). We investigate the inner hidden structure of this "textbook". Our calculations show that "modern textbook" contains an extremely interesting system of statistical duplicates.

Speaking loosely, we might say that the commonly accepted "textbook" of ancient and medieval European, Mediterranean, Egyptian and Middle Eastern history is a fibred (layered) chronicle obtained by gluing together four nearly identical copies of a shorter chronicle A. The chronicle-original A describes the events from 9th c.A.D. to 17th c.A.D. The other three chronicles are obtained from A by redating and renaming the events described in them; we rigidly move A in its entirety backwards in time by 333, 1053 and 1778 years (approximately). Thus, the "textbook" was obtained (many years ago) by duplication its smaller part, namely - from the chronicle A. Almost all of the information in the original chronicle A is concentrated to the right of 960 A.D. In reality we have extensive historical records only starting from 960 A.D. Thus, the currently accepted global chronology before the 13th century A.D. is in need of radical changes. Conjecture: we have to redate certain blocks of ancient events which until now have been placed in very ancient times. To do this we must take out large parts from textbook (namely, the part before 10th c.A.D.) and move forward in time, as indicated above. After this procedure, one finds that the known written history of Europe, the Mediterranean, etc. becomes much shorter: most of the events which are traditionally dated today earlier that the 10th century A.D. (ancient Rome, ancient Greece et cetera) turn out to be in the time interval from 10th century A.D. to 17th century A.D. Revising chronology in this way, one finds that many of the old paradoxes in traditional dating disappear.
