According to Roscoe, definite stages are well defined and can be definitely traced in their paintings. At first the themes were things and later they were men and the human body as a design for the artist is clearly portrayed. There was a "breast and furrow" type of painting that marked almost every object with which they had to do. The piano with iron keys was very much like such instruments found in Egypt. The Jews' harp was found in many quarters. There can be no doubt that music had its place in the life of the Mashonaland. But music is a fine art and its value lies largely if not wholly in its appeal to our aesthetic natures. What can be the meaning of such evidences of love of music among the African tribes? Can it not be interpreted as their response to the appeal of the beautiful? Of the great defensive walls of Zimbabwe Bent says: "The fort is a marvel with its tortuous and well-guarded approaches; its walls bristling with monoliths and round towers, its temple decorated with tall weird-looking birds, its huge decorated bowls. The only parallel that I have seen were the long avenues of menhirs near Carnac in Brittany. One cannot fail to recognize the vastness and power of this ancient race, their greatness of constructive ingenuity and their strategic skill."[14] Of course, there is evidence that the present inhabitants of those ruined cities were not the tribes that once ruled mightily in these regions. Bent himself holds that such high culture must have come from another people. The very fact that the present population seems so far below the level of culture that once prevailed there is the only evidence upon which Bent predicates his argument that another race than the Negroes were the bearers of this great culture. However, it is hardly probable that the level of culture was foreign to the Negroes who lived in the palmy days of Zimbabwe. There must have been an overlapping of cultures even if we grant that another race produced the culture of this region. It is hardly probable that a dominant race would have wholly abdicated in favor of the natives and it is still less probable that the natives could have dislodged a race so strongly fortified. It is highly probable that the same race of people could have produced the peoples who occupied the level of these two very different cultures. No one supposes that the inhabitants of Athens today are equal to the Greeks of the days of Pericles. Yet they are connected with the same great race.
