Comment:
Note the similarity of the way in which the symbols for the noun tent and the noun house are constructed. In fact, there are two groups of Indus symbols which follow the same logical pattern. They are:
Permanent Housing: perimeter wall; house; city, and;
Transient Housing: contour; tent; caravanserai.
