During the first 30 years of this period we are in the warm phase of the
100-year cycle, but in this instance the cycle had shortened to 70 years.
Notice how the latter part of the warm period was considerably drier than
the former part. The drop in temperature and rainfall between 540 and 535 is
typical in that it breaks the warm period into two parts.
Notice particularly, however, how uniformly red are the entries for the
main events of the warm period and how quickly the pattern shifts as it
turned cold between 520 and 515.
While at the opening of the warm period strong government~ revived, and
while there was a revival of learning, this is not a major Golden Age
period. Golden Age periods, with their conspicuously good leadership and
great outcropping of geniuses, occur on the average of about every 200
Remember that this is near the opening of a 500-year cycle. Consequently,
we can expect profound events to be occurring, and they are. This period is
famous for its origin of rational thought in the history of human
intelligence. It was a small beginning, but a profound one. The human mind
is rising out of semi-barbarism. Here occurred the crude beginnings of
science and philosophy. Most of the early philosophers we know about only
indirectly or through fragments of their writings. Their views were a
mixture of rational thinking and superstition, but it was an important
beginning. All of their names, which would mean little to the general
reader, have not been included. Among them was Pythagoras, who founded a
famous school of thought.
The fact that Buddha and Confucius flourished at this time indicates that
the awakening was not confined to the region of the Meditertanean.
The great revolution that crowded the sixth century with important events
will reach a climax during the early part of the next century. It was one of
the great dynamic periods of history and the Golden Age of Greece.
Note the increase of despotism and atrocities, typical warm-dry events,
during the last half of the warm period. While the period between 550 and
520 B.C. is known as the Age of Tyrants, such a statement is misleading
because tyrants emerge universally during warm periods in history,
especially during the warm-dry phases of the cycle. This does not mean that
there are no tyrants during cold times, but it does mean that during the
latter parts of the warm periods they fit into the total pattern. Frequently
they are deliberately sought, even by the people at such times; while during
cold times they do not fit into the total pattern, and efforts, generally
successful sooner or later, are made by the people to oust them from office.
Notice the migrations toward the end of this period. The Gauls, Teutons,
and Celts were western European, north of the Mediterranean; and the Slavs
and Scythians were in western Asia. There were almost surely other
migrations than those that were recorded. The Scythians were Monngoloid
peoples like the Tartars who will be heard from many times. The Slavs were
ancestors of the present Slavs.
