## Works of N.A.Morozov

About fifty years ago, N.A.Morozov found three pairs of
ruling ancient dynasties for which the sequences of lengths
(periods) of reign, represented visually on the time line, bore a
striking resemblance to one another. He suggested that in each
case the two dynasties are actually reflections of a single real
dynasty which "became multiplied" as a result of a mistaken
dating of the different texts describing the same events. But it
is not enough to rely upon subjective impression. For this reason
we set about creating a formal quantitative method for
determining whether two dynasties are merely different
manifestation of a single dynasty ("dependent dynasties") or are
truly distinct ("independent dynasties"). The application of the
method to historical data traditionally believed to belong to
earlier than the 13th c.A.D. unexpectedly led to the discovery of
pairs of dynasties regarded as independent in all the senses, but
for which the special proximity coefficient is extremely small.
