Archaeology
By far the most exquisite and obscure artefacts unearthed to date are the small, square steatite (soapstone) seals engraved with human or animal motifs. A large number of seals have been found at such sites as Mohenjo-Daro and Harappa. Many bear pictographic inscriptions generally thought to be a form of writing or script. Despite the efforts of philologists from all parts of the world, and despite the use of modern cryptographic analysis, the signs remain undeciphered. It is also unknown if they reflect proto-Dravidian or other non-Vedic language(s). The ascription of Indus Valley Civilization iconography and epigraphy to historically known cultures is extremely problematic, in part due to the rather tenuous archaeological evidence of such claims, as well as the projection of modern South Asian political concerns onto the archaeological record of the area. This is especially evident in the radically varying interpretations of Harappan material culture as seen from both Pakistan and India-based scholars.
