"The fire-altars of Kalibangan and Lothal are so far without parallels at Mohenjo-daro and Harappa. Indeed, it has been asked [by Raymond and Bridget Allchin]: "Fire- worship being considered a distinctly Indo-Aryan trait, do these {ritual hearths of Kalibangan] carry with them an indication of an Indo-Aryan presence even from so early a date?" This hypothesis new seems quite plausible to me, if "Indo-Aryan" here is understood to refer to carriers of the Bronze Age culture of Greater Iran, who had become quickly absorbed into the Indus Civilization, culturally and linguistically. It is supported further by the cylinder shape of the famous Kalibangan seal showing a Durga-like goddess of war, who is associated with the tiger. The goddess on the Kalibangan cylinder seal is said to be similar in style, especially the headdress, to one depicted on a cylinder seal from Shahdad [in Kerman on the desert of Lut in Iran, a major centre of the Bronze Age cultural tradition]. Seated lions attend to a goddess of fertility on a metal flag found at Shahdad."
