Indus Valley Seals
Thousands of inscribed clay seals from Mohenjo-Daro in Pakistan remain undeciphered, concealing vital details about this sophisticated urban civilization. Archaeologists have found these palm-sized square seals since the 1920s. They depict unicorns, bulls, and contain a script with approximately 400 symbols that might represent a complete writing system. These 4,500-year-old artifacts were likely used for trade or administration. Despite AI attempts to crack the code, their meaning remains a mystery.
