This seal from Mohenjo-daro contains, perhaps more compactly than any other, what we can tell of ancient Indus beliefs and traditions. Several script signs are interspersed with the figures along the top of the seal and a single sign is placed at the base of the tree. This scene may represent a special ritual sacrifice to a deity with seven figures in procession. The seal has a grooved and perforated boss and the edges are worn and rounded from repeated use.
It shows a deity with horned headdress and bangles on both arms, standing in a pipal (sacred fig) tree and looking down on a kneeling worshiper. A human head rests on a small stool. A giant ram and seven figures in procession complete the narrative. The figures wear a single plumed headdress, bangles on both arms and long skirts. Parpola writes of these: "The Pleiades hold a prominent place as the mothers or wet nurses of the newborn infant in one of the most ancient and central Hindu myths, that of the birth of the war-god Rudra/Skanda, who evidently represents, among other things, the victorious rising sun (and as vernal sun the new year). The Pleiades are said to have been the wives of the seven sages, who are identified with the seven stars of the Great Bear."
More of his interpretation can be found in Deciphering the Indus Script.
