Comment:
It is interesting to note that Asko Parpola lists 29 Indus signs that he classifies as variants of this Indus character¹. However, it should not be assumed that all of the symbols in Parpola's list carry the same meaning. An analysis of the symbols in Parpola's list is beyond the scope of this dictionary.
