Seals and sealings
Concept First
Seals and sealings were the Harappan equivalent of a tamper-proof courier label. They served two purposes: security (ensuring a package wasn't opened) and identification (showing who sent it). The key physical idea is that a sealing is a clay impression that, if broken, proves the package was tampered with.
How It Worked
- The Package: A bag of goods was tied shut with a rope.
- The Seal: A small, carved stone (the seal) was pressed into wet clay placed over the knot.
- The Sealing: The clay hardened, leaving a raised impression of the seal's design. This hardened clay is the sealing. …
This figure shows a sealing — a lump of clay — from the site of Ropar (in present-day Punjab, India). A sealing is not a seal itself; it is the clay impression left after a seal was pressed onto wet clay.
The image likely depicts a small, irregularly shaped piece of clay. On its surface, you can see one or more impressions — the marks left by the engraved face of a seal. These impressions might show a motif (like an animal or a symbol) and possibly a short inscription in the Harappan script. The clay would have originally been wrapped around the knot of a rope tied around a bag or container.
What this teaches about the topic:
- Long-distance trade and communication: The sealing was a practical tool for sending goods. The sender would press their seal onto wet clay over the knot of a bag. If the sealing arrived intact, the receiver knew the bag had not been opened in transit.
- Identity and security: The impression on the sealing acted like a modern signature or stamp — it identified the sender (or the merchant) and guaranteed the contents were untouched.
- Material evidence: Because clay sealings survive well in dry conditions, they are one of the most common artefacts found at Harappan sites. Ropar, like many other Harappan settlements, was part of a vast network of exchange, and this sealing is a direct piece of evidence for that system. …
