This Indus motif is a pictograph of a bull. The bull is depicted with one horn. The single horn draws attention to the head, which gives us a link with the Latin word capitalis, which means 'of the head', and thence to the word chattel.

Variations on the chattel motif are the most common motifs found on the Indus seals. I haven't been able to check every instance of this motif against the associated inscription, but I would expect all of the inscriptions to refer to movable property.
