This is a pictograph of an adult person with the addition of what may be two wings or two quivers on the shoulders. It resembles depictions of Ishtar or Venus from western Asia. The Indus inscriptions indicate that the being is of some importance because it possesses both a domain or realm, and goods. Hence, my conclusion is that Mahadevan's sign number 1339 depicts a god or goddess, which may have been Ishtar.
