The Indus Dictionary Project
Numerals are some of the most difficult symbols to decipher in Indus script, because counting rods are portrayed as lines, and lines are also used to represent concepts such as the duality of light and dark, and things such as tracks. Please bear this in mind when you are trying to identify an Indus sign.
I have chosen the numeral three to head up this section.
