Depending on their size, these projectiles would have functioned either as spear points or atlatl dart tips. As Chinese metallurgy led to different grades of bronze, so did Roman metallurgy develop new and varying grades of brass alloys that had varying ratios of copper and zinc for particular applications. Several thousand years before the Christian era a flourishing civilization existed in Hindustan, and sites on the Indus are now being systematically examined.
