the Past As we have seen, it is not the Harappan script that helps in understanding the ancient civilisation. Rather, it is material evidence that allows archaeologists to better reconstruct Harappan life. This material could be pottery, tools, ornaments, household objects, etc. Organic materials such as cloth, leather, wood and reeds generally decompose, especially in tropical regions.
What survive are stone, burnt clay (or terracotta), metal, etc. It is also important to remember that only broken or useless objects would have been thrown away. Other things would probably have been recycled. Consequently, valuable artefacts that are found intact were either lost in the past or hoarded and never retrieved.
In other words, such finds are accidental rather than typical. . Classifying finds Recovering artefacts is just the beginning of the archaeological enterprise. Archaeologists then classify their finds.
One simple principle of classification is in terms of material, such as stone, clay, metal, bone, ivory, etc. The second, and more complicated, is in terms of function: archaeologists have to decide whether, for instance, an artefact is a tool or an ornament, or both, or something meant for ritual use. An understanding of the function of an artefact is often shaped by its resemblance with present-day things – beads, querns, stone blades and pots are obvious examples. Archaeologists also try to identify the function of an artefact by investigating the context in which it was found: was it found in a house, in a drain, in a grave, in a kiln?
Sometimes, archaeologists have to take recourse to indirect evidence. For instance, though there are traces of cotton at some Harappan sites, to find out about clothing we have to depend on indirect evidence including depictions in sculpture. Archaeologists have to develop frames of reference. We have seen that the first Harappan seal that was found could not be understood till archaeologists had a context in which to place it – both in terms of the cultural sequence in which it was found, and in terms of a comparison with finds in Mesopotamia.
