when the ancient man discovered the use of these metals. It is
not to be supposed, however, that these three different periods of
early human civilization were divided by any hard and fast line of
division. They represent only a rough classification, the passage
from one period into another being slow and gradual. Thus the
implements of stone must have continued to be used for a long time
after the use of bronze became known to the ancient man, and the
same thing must have occurred as he passed from the Bronze to the
Iron age. The age of bronze, which is a compound of copper and
tin in a definite proportion, requires an antecedent age of copper;
but sufficient evidence is not yet found to prove the separate
existence of copper and tin ages, and hence it is considered pro-
bable that the art of making bronze was not invented in Europe,
but was introduced there from other countries either by com-
merce or by the Indo-European race going there from outside.*
Another fact which requires to be noted in connection with these
ages is that the Stone or the Bronze age in one country was
not necessarily synchronous with the same age in another country.
Thus we find a high state of civilization in Egypt at about 6000
B. C., when the inhabitants of Europe were in the early stages
of the Stone age. Similarly Greece had advanced to the Iron
age, while Italy was still in the Bronze period, and the West
of Europe in the age of Stone. This shows that the progress of
civilization was slow in some and rapid in other places, the rate
of progress varying according to the local circumstances of each
place. Broadly speaking, however, the three periods of Stone,
Bronze and Iron may be taken to represent the three stages of
civilization anterior to the historic period.
Of these three different ages, the oldest or the Stone
age is further divided into the Palæolithic and the Neolithic
period, or the old and the new Stone age. The distinction is
