Prehistoric art had its beginning, as far as we know, in the last Ice
Age, archaeologically in the Later Paleolithic.
This last Ice Age had two cold high points each of which, if one
may mix metaphors, must have had a long duration. When we con-

The Diluvial Period consists
of four Ice Ages interspersed
with three warmer periods or
Interglacials. According to the
results of the most recent geo-
logical and paleontological re-
search, man appeared in Europe
during the first Interglacial, that
is, many hundreds of thousands
of years ago, something which
is indicated by the presence of
certain stone artifacts in early
diluvial strata. In the course of
time he developed a series of
what we call stone industries

haps “sequential” structure would be a better word, since we cannot
yet be very sure of dates. This begins with the Old Stone Age (the
Paleolithic: Chellean to Magdalenian) and goes through the Mid-
dle Stone Age (the Mesolithic: Azilian, Tardenoisean and early
Campignian, etc.) into the New Stone Age (the Neolithic: begin-
ning around 4000 B. C.).
